Rum Cake from Scratch with Butter-Rum Syrup

Rum cake is a golden butter Bundt cake soaked with a warm butter-rum syrup after baking, giving it a moist, fine crumb and a distinctly fragrant rum flavor. This version starts with flour, butter, eggs, and milk, with a little cinnamon and nutmeg in the background. There is no cake mix or pudding mix, and the syrup supplies the finish without a thick layer of icing.

A cake like this suits the slower end of a holiday meal, when coffee is poured and a thin slice feels just right. The browned edges bring a little contrast to the tender middle, while the butter and vanilla soften the rum’s sharper notes. It looks generous on a platter without needing piped frosting or a separate filling.

Keep this rum cake recipe for a day when you can give the soaking and cooling their full time. The useful details are knowing when the center is baked, releasing the cake before the syrup makes the pan sticky, and waiting between each addition. You can also make it the day before serving, leaving only the slicing for the table.

    This is a golden butter cake with a rum soak, rather than a dried-fruit black cake or a yeast-raised baba. The rum cake contains alcohol, including rum stirred into the syrup after heating.

    Why This From-Scratch Rum Cake Works

    This rum cake is built to keep the character of a butter cake after soaking: a fine crumb, a defined slice, and rum flavor that reaches beyond the surface. The batter and syrup are prepared separately so the cake can develop its structure before taking on the extra liquid.

    • A cake crumb beneath the syrup. Creamed butter, eggs, and all-purpose flour create the base, while the milk supplies liquid for the batter itself. Unlike versions based on cake mix and instant pudding, this rum cake gets its crumb from the creamed butter batter, with the syrup adding moisture after baking.
    • Rum flavor in two places. The smaller quantity in the batter gives the cake its own rum note, while the larger quantity in the syrup adds aroma after baking. That division gives the finished slice a pronounced rum character without putting all of the spirit and its liquid into the unbaked batter.
    • Moisture beyond a surface glaze. Holes through the exposed underside and gradual application help the syrup enter the crumb instead of remaining only on the decorative crust. The aim is a moist interior that still holds a slice, rather than a dry center beneath a wet coating.
    • A release check before soaking. Unmolding the baked cake once before adding syrup lets you find any sticking while the crumb has not yet taken up the soak. Returning it to the pan gives the cake support during absorption, with the final release reserved for the cooled cake.

    Why You’ll Love This Butter-Rum Bundt Cake

    The practical appeal is a full-sized rum cake that needs no frosting session and can be finished before the day you plan to serve it. Most of the time is spent baking, soaking, and cooling rather than working at the mixer.

    • A familiar shopping list: The cake uses everyday baking ingredients alongside the rum, with no specialty pudding powder to find.
    • No elaborate decorating: The Bundt shape and a simple syrup finish do the work.
    • Room for a gathering: Sixteen dessert slices make portioning straightforward when other dishes are on the table.
    • A day-ahead option: Bake, soak, and cool the cake before your serving day.
    • Useful leftovers: Wrap individual slices for the freezer so you can take out only what you need.

    Who This Rum Cake Is Perfect For

    Choose this rum cake for the way you want dessert to taste and feel, and for the kind of baking you enjoy. It suits a deliberate baking session and a preference for a moist, substantial slice with a clearly recognizable spirit flavor.

    • For people who want to taste the rum. The aroma is part of the attraction, especially in the syrup added after baking. This is a good match for someone who enjoys rum-flavored desserts; it is not a suitable choice when an alcohol-free dessert is needed.
    • For a moist cake with some body. If you like a slice that yields easily to a fork but stays together on the plate, this is closer to that preference than a very airy sponge. The soak is part of the eating experience, so it also suits someone who finds plain butter cakes a little too dry for their taste.
    • For a centerpiece where the cake is the attraction. The fluted shape gives the table something generous to cut into, while the inside remains a single, uninterrupted crumb. It suits a preference for cake itself over stacked layers of filling and frosting.
    • For bakers who enjoy judging texture. There is hands-on work beyond mixing: handling the warm cake, noticing how the syrup absorbs, and allowing the final rest to take as long as it needs. It is a satisfying choice if those small decisions appeal to you and you can leave room in the day for them.

    The Baking Science Behind a Moist Rum Cake

    The texture of rum cake comes from two separate changes: heat turns the batter into a porous cake, then the syrup adds liquid to that structure. Understanding the air, starch, proteins, and butter explains why a cake can be fully soaked yet still need time before it is ready to slice.

    Soft Butter Holds the Air That Gives the Cake Lift

    During creaming, sugar crystals help incorporate air into the butter. Butter that is soft but still holds its shape can retain those small pockets; melted butter cannot hold them in the same way. In the oven, expanding gases enlarge the spaces in the batter while baking powder supplies additional carbon dioxide. This is why a pale, aerated mixture matters more than simply making the butter and sugar look combined.

    Heat Builds the Framework for the Soak

    As the cake heats, flour starch absorbs water and swells, while proteins in the eggs and flour help form the framework around the expanding air spaces. The Exploratorium describes this structure-setting process in butter cakes. A browned crust and a set center are different events: the outside can look finished while the middle is still batter. Syrup can moisten the framework once it exists, but it cannot replace the changes that baking must complete.

    Why Syrup Needs More Than a Wet Surface

    A baked rum cake contains many small spaces within its crumb. The skewer holes give liquid additional entry points, while gradual pouring gives it time to move beyond the surface. A pool means liquid is arriving faster than it is being taken in at that point; it is not proof that the entire cake is saturated. This explains why an evenly moistened slice depends on absorption, not simply on how glossy the cake looks.

    Cooling Changes Firmness, Not Just Temperature

    Warm butter is softer than cool butter, so the same soaked crumb can feel more fragile while warm and more cohesive after resting. Absorbing syrup and losing heat therefore answer different questions: one concerns where the liquid has gone, and the other concerns how well the cake can support itself. A slice that firms up as it cools has not necessarily dried out; temperature alone changes the way its butter-rich crumb feels.

    Ingredients for the Cake and Butter-Rum Syrup

    Use all-purpose flour, softened unsalted butter, and dark or aged rum at 40% ABV for this rum cake. Measure the cake and syrup ingredients separately so the two quantities of butter, sugar, rum, and vanilla stay in their intended places.

    Ingredients for a from-scratch rum cake and butter-rum syrup.

    Ingredient List

    Set out the pan coating first, then measure one group for the batter and a second for the syrup. The butter, sugar, rum, and vanilla in the syrup are additional to the amounts used in the cake.

    For the Pan

    • Baking spray with flour, enough for a thin, complete coating of the Bundt pan

    For the Cake

    • 2 1/2 cups (300 g) all-purpose flour, weighed or spooned into the cup and leveled
    • 2 1/2 teaspoons (10 g) double-acting baking powder
    • 1/2 teaspoon (3 g) fine salt
    • 1/2 teaspoon ground cinnamon
    • 1/4 teaspoon ground nutmeg
    • 1 cup (227 g) unsalted butter, softened to about 65–68°F (18–20°C), not melted
    • 1 1/4 cups (250 g) granulated sugar
    • 4 large eggs, about 200 g without shells, at room temperature
    • 2 teaspoons (10 ml) vanilla extract
    • 3/4 cup (180 ml) whole milk, at room temperature
    • 1/4 cup (60 ml) dark or aged rum, 40% ABV (80 proof)

    For the Butter-Rum Syrup

    • 1/2 cup (113 g) unsalted butter
    • 3/4 cup (150 g) granulated sugar
    • 1/4 cup (60 ml) water
    • 1/8 teaspoon fine salt
    • 1/2 cup (120 ml) dark or aged rum, 40% ABV (80 proof), added off the heat
    • 1 teaspoon (5 ml) vanilla extract, added after heating

    Choosing Dark or Aged Rum

    Choose dark or aged rum labeled 40% ABV, also called 80 proof. Different bottles bring different flavor notes, so pick a rum whose aroma you enjoy, but keep the amount and strength the same. Overproof rum is not a direct substitute here.

    Cooking does not guarantee that all alcohol evaporates, as the USDA’s alcohol-retention data show. This rum cake also receives rum after the syrup comes off the heat, so it contains alcohol. Those general data cannot tell you the exact amount remaining in a slice; choose a dessert made without alcohol when that is required.

    Flour, Butter, and Ingredient Temperature

    Weigh the flour at 300 g if possible. For this rum cake, if using cups, spoon the flour into the cup and level the top rather than packing it down. Use fine salt for the measured volume, since a coarse kosher salt can occupy the spoon differently.

    The butter should be soft at about 65–68°F (18–20°C), not melted. Bring the eggs and milk to room temperature before mixing so very cold additions do not abruptly firm up the butter. A little graininess after the eggs can smooth out when the flour is added; a greasy mixture with melted butter is a different problem.

    The Bundt Pan and Tools You’ll Need

    The 12-cup metal Bundt pan is the most important equipment choice for this rum cake. Its capacity gives the batter room to rise, while a rack, platter, and clean pan let you complete the first release before the sticky syrup is added.

    • Bundt pan and oven: A 12-cup metal Bundt pan, with the oven rack in the center and the oven set to 325°F (165°C). Keep the batter below three-quarters of the pan’s capacity.
    • Measuring tools: A digital scale, US measuring cups, and measuring spoons for the flour, sugar, butter, and liquids.
    • Mixing tools: Mixing bowls, a stand mixer fitted with the paddle attachment or a hand mixer, and a flexible spatula for scraping the bowl.
    • Checking, cooling, and serving: A thin skewer, wire cooling rack, nonmetal tool for gently loosening the edges, serving platter, and slicing knife.
    • Syrup tools: A saucepan holding at least 1.5 liters, a whisk or spoon, and a heatproof measuring cup so the rum is ready to add away from the burner.

    Before You Start Mixing the Batter

    For the rum cake batter, have the softened butter, room-temperature eggs and milk, prepared pan, and cooling rack ready before you begin. Measure the syrup ingredients into a separate group so you can concentrate on releasing the cake when it comes out of the oven.

    I’ve learned to slow down when soaking a cake. It’s tempting to pour on the syrup and move straight to the next step, but a little patience makes the process easier to judge. For this rum cake, I add the syrup in four stages, letting each addition soak in before pouring the next. If syrup is still sitting on the surface, that’s my cue to pause.

    • Check the pan’s 12-cup capacity rather than judging by its width alone.
    • Coat the narrow grooves and center tube, not just the broad bottom surface.
    • Clear a stable surface for the rack and platter before handling the warm cake.
    • Set aside at least two hours after the final syrup addition, with extra time available if the cake remains warm.

    What to Expect from the Batter, Syrup, and Finished Cake

    The rum cake batter will be thick and fall from the spatula in broad ribbons, while the syrup should be fluid rather than thick like icing. Before soaking, the baked surface should be golden and stable; after the rest, the crumb should be moist without free syrup collecting around it.

    A few damp crumbs on the skewer can be normal when checking the baked cake. Raw, paste-like batter is not. The final slice will feel more tender after soaking, but cooling is still important because a warm cake is harder to handle neatly.

    How to Make Rum Cake from Scratch

    Make the rum cake in this order: mix and bake the batter, check that it releases from the pan, then return it for gradual soaking. The first release comes before the syrup; the final release comes after absorption and complete cooling.

    1. Prepare the Oven and Bundt Pan

    Heat the conventional oven to 325°F (165°C) with a rack in the center. Coat a 12-cup metal Bundt pan with a thin, complete layer of baking spray containing flour, reaching into the grooves and around the center tube. Avoid leaving pools of spray in the bottom.

    What you should see: Every part that will touch batter has an even coating, including the narrow details around the tube.

    2. Combine the Dry and Liquid Ingredients

    Whisk the flour, baking powder, fine salt, cinnamon, and nutmeg together in a bowl. In a separate measuring cup or bowl, combine the milk with the 1/4 cup (60 ml) rum reserved for the cake. Keep the larger rum quantity for the syrup separate.

    What you should see: The dry mixture has an even color with no obvious pockets of baking powder or spice.

    3. Cream the Butter and Add the Eggs

    Beat the softened butter and granulated sugar on medium speed for 3–4 minutes, scraping the sides and bottom of the bowl. Add the eggs one at a time, beating about 20–30 seconds after each addition, then mix in the vanilla.

    Butter and sugar creamed until pale and fluffy.

    What you should see: The butter and sugar look lighter and aerated before the eggs go in. The mixture may look slightly grainy after the eggs, but it should not look melted or oily.

    4. Mix the Batter Gently

    On low speed, add the dry ingredients in three additions and the milk-rum mixture in two, alternating them and beginning and ending with the dry ingredients. Stop when the flour streaks disappear. Use a spatula to check the bottom of the bowl for unmixed batter.

    What you should see: The batter is thick and cohesive, falling in broad ribbons, with no dry flour left at the bottom.

    5. Bake Until the Center Is Set

    Transfer the rum cake batter to the pan, smooth the surface, and tap the pan very gently on the counter. Do not fill it beyond three-quarters of its capacity. Bake for about 55–70 minutes, beginning the first check at 50 minutes.

    Insert a thin skewer into the thickest part of the ring, away from the metal tube. If it carries raw batter, continue baking. If the top is already well browned, cover it loosely with foil while the center finishes.

    What you should see: The surface is golden, the cake springs back with a light touch, and the skewer has no raw batter. A few moist crumbs are fine.

    6. Release the Cake and Return It to the Pan

    Let the baked rum cake rest in its pan on a rack for 10 minutes. Gently loosen the outer edge and the area around the center tube with a suitable nonmetal tool, then invert it onto the rack. Clean and dry the pan, and gently place the cake back inside in its original baking orientation.

    Support the cake while turning it, and do not force it into the pan. If it resists the first release, work gently around the edges rather than pulling on the crumb. Releasing it now checks the shape before syrup makes the contact surfaces sticky.

    What you should see: The cake has released as one piece and sits back in the clean pan without being pushed down or compressed.

    7. Make the Butter-Rum Syrup

    In a saucepan holding at least 1.5 liters, heat the syrup butter, sugar, water, and salt over medium heat, stirring until the butter has melted and the sugar has dissolved. Bring to a gentle boil and boil for 2 minutes. Remove the saucepan from the heat and move it away from any flame.

    Slowly stir in the 1/2 cup (120 ml) rum, then the vanilla. Measure the rum before adding it, and do not pour directly from the bottle over a burner. The syrup may bubble as the rum goes in.

    What you should see: The syrup is fluid with no noticeable sugar granules and no caramel coloring.

    8. Add the Syrup in Four Stages

    With the rum cake back in the pan, use a thin skewer to make evenly distributed holes through the exposed surface, going almost to the bottom without puncturing the decorative crust. Pour the warm syrup over the cake in four roughly equal additions, waiting for each to absorb before continuing.

    Allow about 15 minutes for preparing and applying the syrup, but take longer if needed. If liquid is sitting on the surface, stop pouring and let it soak in. Do not add another portion over a pool or invert the cake simply to hide unabsorbed syrup.

    What you should see: The exposed surface takes in each portion before the next is added; you are watching absorption rather than trying to finish pouring by the clock.

    9. Cool Completely, Unmold, and Slice

    Leave the rum cake for at least 2 hours after the final syrup addition, allowing it to absorb the liquid and cool completely. Gently loosen the edges and invert onto a serving platter. Slice only when the cake is cool and there is no free syrup remaining.

    If making it for the next day, cover only after it has cooled completely. If it still feels warm after two hours, give it more time before the final release and slicing.

    What you should see: The cake feels cool, holds its shape on the platter, and cuts into a moist slice without a pool of syrup around it.

    Rum Cake Doneness: Baked, Soaked, and Ready to Slice

    Rum cake has three separate readiness checks. A baked center tells you it can leave the oven; absorbed syrup tells you the soak is progressing; complete cooling tells you it is ready for the final release and a cleaner slice.

    Expert Tips for Even Soaking and Neat Rum Cake Slices

    A level pan, a gentle touch with the skewer, and a clean knife help the rum cake absorb its syrup evenly and keep its shape when cut.

    • Keep the pan level during the soak. A rack that rocks or rests on a folded towel can tilt the cake and send syrup toward one edge; set it on a stable, level surface so one side does not receive most of the liquid.
    • Stir any butter back through the syrup. If a buttery sheen gathers on top while the saucepan stands, stir gently off the heat just before the next addition; this redistributes the butter instead of leaving one pour mostly fat and another mostly sweet liquid.
    • Draw the skewer straight back out. Dragging it sideways can tear channels through the warm crumb; withdraw it along the path it entered so the small holes stay separate and the cake keeps its structure.
    • Wipe the blade between slices. Sticky syrup and crumbs left on the knife can pull at the next cut; wiping them away and using a light sawing motion helps preserve the ridged edge without pressing down on the soft center.

    Rum Cake Mistakes: Sticking, Dense Crumb, and Pooled Syrup

    When troubleshooting rum cake, identify whether the problem began in mixing, baking, release, or soaking before trying to fix it. Some issues can be corrected at that stage; a torn cake or a soaked cake with a raw center cannot be restored simply by adding more syrup.

    ProblemPossible causePreventionWhat to do now
    Cake sticks or tearsUncoated grooves or sticky contact after syrupCoat every groove and check the first release before soakingLoosen the edges gently with a nonmetal tool; do not pull at the crumb. A broken section will not regain its structure with syrup
    Crumb is excessively densePacked flour, poorly aerated butter, or prolonged mixing after flourWeigh the flour, cream softened butter, and stop when combinedDistinguish a close but cooked crumb from raw batter; change the mixing or measurement issue on the next bake

    Beautiful Ways to Serve Rum Cake

    Serve rum cake at room temperature, when the buttery crumb is tender. Choose a finish that adds a little contrast while leaving the golden ridges and the cut face visible.

    A Glossy Slice on a Simple Plate

    Set a slice upright on a small white plate, with its cut face turned outward. For the glossy finish pictured here, prepare extra butter-rum syrup separately and spoon a little along the ridged edge just before serving, letting a small ribbon reach the plate. Use the full measured soaking syrup in the cake; the finishing syrup is additional.

    Soft Cream Beside the Golden Crust

    A loose spoonful of homemade whipped cream gives the rich cake a lighter, softer companion. Place it beside the slice so each forkful can pick up as much or as little as you like, and leave the amber crust uncovered. Add the cream at serving time and refrigerate it separately until then.

    Vanilla Ice Cream for a Cool Contrast

    Pair a room-temperature slice with a small scoop of vanilla ice cream. Keep the scoop to one side, where the melting cream can meet the cake at the edge instead of soaking the entire slice. Assemble each plate when it is ready to be eaten, so the contrast between cool ice cream and tender cake remains noticeable.

    A Bundt Platter with the First Slices Cut

    For a shared dessert table, arrange two or three slices slightly apart beside the remaining cake. The open spaces show the crumb and make it easy to lift a portion without crowding the platter. Put any cream or extra syrup in separate dishes so guests can choose their own finish.

    Keeping Rum Cake Moist: Storage and Make-Ahead

    Cover plain rum cake once it has cooled completely and keep it for up to 3 days in a cool room. If the room is warm, refrigerate it and let individual slices temper before serving. Add cream or other perishable garnishes only at serving time.

    Storing the Whole Cake or Leftover Slices

    Use a covered cake container for the whole rum cake, or wrap the cut portions to protect the exposed crumb. For a day-ahead dessert, finish the soaking and full cooling before covering it. Prepare the cake itself in advance rather than leaving the mixed raw batter overnight.

    Freezing, Thawing, and Serving Again

    Wrap cooled rum cake slices individually and freeze for up to 1 month for best quality. Thaw them while still wrapped in the refrigerator, then let the portions temper before serving. Keep any cream or ice cream separate; warming a slice does not make the cake alcohol-free.

    Plan Your Rum Cake Around Serving Time

    Start about four hours before serving, with extra room for slower absorption or cooling. For a less time-sensitive plan, make the rum cake the day before and leave only portioning and garnishes for the meal.

    From the startDependency
    0–25 minutesPrepare the pan and mix the batter
    25–80/95 minutesBake for about 55–70 minutes, using the center checks
    Next 10 minutesRest in the pan before the first release; allow extra handling time if needed
    Next approximately 15 minutesMake and apply the syrup gradually
    At least the next 2 hoursCount from the final syrup addition; continue resting until completely cool
    About 3 hours 45 minutes to 4 hours or longerUnmold and slice only when the cake is cool and no free syrup remains

    Choosing Rum and Understanding Recipe Changes

    For this rum cake, the straightforward flavor choice is another dark or aged rum at the same 40% ABV. Keep the quantities unchanged so you are changing the rum’s character rather than the amount of liquid in the cake or syrup.

    Rum extract, extra milk, and overproof rum are not interchangeable with the rum used here. Adding cocoa changes the dry ingredients, and gluten-free flour or a smaller pan changes how the batter behaves. For mini Bundts, loaf pans, or a chocolate version, use a recipe written for that format rather than carrying over this cake’s baking time.

    Do not double the rum cake batter into one pan. The 12-cup Bundt and its three-quarter-full limit remain important even when you want more servings. If nuts are served alongside the cake, keep them as a separate garnish rather than adding an unmeasured layer to the pan.

    Rum Cake Questions, Answered

    The rum, pan size, and soaking time are the choices that matter most when planning this rum cake. Keep the measured rum strength and the full-sized Bundt format in mind before making a change.

    Why does rum cake stick to the pan?

    Uncoated grooves or sticky syrup against the pan can make the cake cling. Coat every groove and the center tube with baking spray containing flour, then make the first release after the 10-minute rest, before soaking. If the cake resists either release, gently loosen the edges with a nonmetal tool rather than pulling at the crumb.

    Why isn’t the syrup soaking into my rum cake?

    Pause before adding any more. Give the portion already on the surface time to enter through the holes and crumb, then continue only when it has absorbed. A visible pool is a reason to wait, not to pour the next portion.

    What kind of rum should I use for rum cake?

    Use dark or aged rum at 40% ABV (80 proof). Keep both the strength and measured amounts the same; a stronger overproof rum or a small amount of extract changes more than the flavor.

    How much alcohol is in rum cake?

    This recipe uses 3/4 cup (180 ml) of 40% ABV rum in total: 1/4 cup (60 ml) in the cake and 1/2 cup (120 ml) in the syrup. The amount of alcohol remaining per slice is unknown. Because the syrup rum is added off the heat, this is not an alcohol-free dessert.

    Can I bake this rum cake in mini Bundt pans or a loaf pan?

    The quantities and baking window here are for one 12-cup metal Bundt pan. Smaller molds and loaf pans need their own portioning and baking guidance, so do not use the 55–70-minute window as a direct conversion.

    Can I make rum cake the day before serving?

    Yes. Finish baking and soaking it, let it cool completely, then cover it for the next day. Keep it in a cool room, or refrigerate it if the room is warm, and add perishable garnishes only when serving.

    Can you freeze rum cake?

    Yes. Cool the cake completely, wrap slices individually, and place them in an airtight container. Freeze for up to 1 month for best quality. Thaw the slices while still wrapped in the refrigerator, then let them lose their chill before serving. Add cream or ice cream only when serving.

    Rum cake gives a bottle usually brought out for a drink a different place at the table. Here, its familiar aroma belongs to a dessert meant to be cut and shared, becoming part of the occasion itself. There is something generous about choosing a cake with such a clear character.

    Return to it when you want to make something for someone who particularly enjoys rum, or when an ordinary weekend leaves room for a favorite dessert. The invitation can be as simple as a message to a friend: there is cake, if you have time.

    At the end, there may be only a curved slice left on the platter. That small remainder has its own appeal: a reminder of the cake you made, and the pleasure of another bite still to come.

    Ingredients

    For the Pan

    • Baking spray with flour, enough for a thin, complete coating of the Bundt pan

    For the Cake

    • 2 1/2 cups (300 g) all-purpose flour, weighed or spooned into the cup and leveled
    • 2 1/2 teaspoons (10 g) double-acting baking powder
    • 1/2 teaspoon (3 g) fine salt
    • 1/2 teaspoon ground cinnamon
    • 1/4 teaspoon ground nutmeg
    • 1 cup (227 g) unsalted butter, softened to about 65–68°F (18–20°C), not melted
    • 1 1/4 cups (250 g) granulated sugar
    • 4 large eggs, about 200 g without shells, at room temperature
    • 2 teaspoons (10 ml) vanilla extract
    • 3/4 cup (180 ml) whole milk, at room temperature
    • 1/4 cup (60 ml) dark or aged rum, 40% ABV (80 proof)

    For the Butter-Rum Syrup

    • 1/2 cup (113 g) unsalted butter
    • 3/4 cup (150 g) granulated sugar
    • 1/4 cup (60 ml) water
    • 1/8 teaspoon fine salt
    • 1/2 cup (120 ml) dark or aged rum, 40% ABV (80 proof), added off the heat
    • 1 teaspoon (5 ml) vanilla extract, added after heating

    Instructions

    1. Prepare the pan and oven: Heat a conventional oven to 325°F (165°C), with a rack in the center. Coat a 12-cup metal Bundt pan with a thin, complete layer of baking spray containing flour, reaching every groove and the center tube.
    2. Combine the dry and liquid ingredients: Whisk together the flour, baking powder, salt, cinnamon, and nutmeg. In a separate jug, combine the whole milk and the 1/4 cup (60 ml) rum for the cake. Use room-temperature milk and eggs.
    3. Cream the butter and sugar: Beat the softened 1 cup (227 g) butter and 1 1/4 cups (250 g) sugar on medium speed for 3–4 minutes, scraping the bowl, until lighter and aerated. Beat in the eggs one at a time, about 20–30 seconds each, then the 2 teaspoons vanilla. The butter should be soft, not melted or oily.
    4. Finish the batter: On low speed, add the dry ingredients in three additions, alternating with the milk-rum mixture in two additions, beginning and ending with the dry ingredients. Stop when no dry streaks remain; scrape the bottom of the bowl with a spatula. The batter should be thick and fall in broad ribbons.
    5. Bake the cake: Transfer the batter to the prepared pan, smooth the top, and tap the pan very gently on the counter. Do not fill above three-quarters of its capacity. Bake for 55–70 minutes, checking from 50 minutes. The top should be golden, the center should spring back gently, and a skewer in the thickest part should show no raw batter. A few moist crumbs are fine.
    6. Release the cake before soaking: Rest the cake in its pan on a rack for 10 minutes. Gently loosen the edges with a nonmetal tool, then invert onto the rack. Clean and dry the pan. Carefully return the cake to the pan in its original baking orientation, with the flat side exposed. Do not force or pull a stuck cake.
    7. Make the butter-rum syrup: In a saucepan holding at least 1.5 liters, heat the syrup butter, sugar, water, and salt over medium heat, stirring until the butter has melted and the sugar has dissolved. Bring to a gentle boil for 2 minutes. Remove the saucepan from the heat and away from any flame. Slowly stir in the 1/2 cup (120 ml) rum, then the 1 teaspoon vanilla. The syrup should be fluid, without perceptible sugar grains or caramel coloring. Never pour rum from the bottle over a burner.
    8. Soak in four additions: Poke evenly spaced holes in the exposed cake with a thin skewer, almost to the bottom but without piercing the decorative crust. Add the warm syrup in four roughly equal portions, allowing each to absorb before adding the next. If syrup pools, pause until it absorbs. Allow about 15 minutes in total for preparing and applying the syrup.
    9. Cool completely and serve: Leave the cake in the pan for at least 2 hours after the final syrup addition, and longer if needed to cool completely. Once fully cool with no free syrup remaining, gently loosen and invert onto a platter. Cut into 16 slices. For next-day serving, cover only after the cake is completely cool.

    Notes

    • Timing: Plan on about 3 hours 45 minutes to 4 hours, with extra time if cooling or absorption takes longer. The displayed 4-hour total uses the upper end of the 55–70-minute bake range. Additional time includes the 10-minute pan rest, about 15 minutes for syrup preparation and application, and at least 2 hours for absorption and cooling.
    • Pan size: Use a 12-cup metal Bundt pan and keep it no more than three-quarters full. A smaller pan, mini Bundts, or loaf pans need different filling and baking times; do not use the full batch in a smaller pan.
    • Rum and alcohol: Use dark or aged rum at 40% ABV (80 proof), not overproof rum. This cake contains alcohol, including rum added after the syrup leaves the heat. Baking and resting do not make it alcohol-free. Rum extract or a nonalcoholic liquid is not an equivalent substitution for this formula.
    • Texture and release: Weigh the flour when possible. Cream soft butter, stop mixing once the flour disappears, and check the baked center before soaking. Syrup cannot correct an underbaked center. If syrup pools, wait rather than adding the next portion.
    • Make ahead and storage: For next-day serving, cool completely before covering. Keep covered for up to 3 days in a cool room for best quality; refrigerate if the room is warm, and let slices lose their chill before serving. Freeze individually wrapped slices in an airtight container for up to 1 month for best quality. Thaw wrapped in the refrigerator, then let the slices lose their chill.
    • Serving: Add whipped cream, ice cream, fruit, or nuts only when serving. The plain cake has no nuts in the batter; toppings are optional and are not included in the nutrition estimate. For the glossy finish, make extra butter-rum syrup separately and spoon it over the slices just before serving. The nutrition estimate covers the cake and the soaking syrup.
    • Nutrition estimate: Nutrition is estimated for 1 of 16 equal slices, including all the syrup and the full amount of rum added, without an adjustment for alcohol evaporation. Pan spray and optional toppings are excluded. Actual values vary with brands, syrup left behind, and slice size.
