Blondie Recipe (Chewy Chocolate Chip Bars)

This blondies recipe makes chewy chocolate chip bars with golden edges, a soft, fully baked center, and the warm flavor of brown sugar and vanilla. Melted butter brings the batter together, and small pockets of semisweet chocolate punctuate each square.

A plain square beside a cup of coffee has an easy, familiar appeal. These are the kind of bars that suit a quiet afternoon as comfortably as a shared dessert plate, with no frosting or elaborate finishing needed.

Keep this recipe for the moments when you want a modest pan of bars and clear guidance on the center. The baking cues help distinguish moist crumbs from melted chocolate, while the cooling instructions tell you when the blondies are ready to slice.

Chocolate Chip Blondies at a Glance

One 8-inch square pan makes nine portions. Mixing is brief, but plan the bake around complete cooling so the bars can be lifted and cut neatly.

Servings	9 squares, cut in a 3 × 3 grid
Method	Whisk the wet ingredients, fold in the dry ingredients, spread, bake, and cool
Best For	An afternoon treat, a dessert plate, or baking ahead for sharing

In short: A single pan of chocolate chip blondies with a short mixing stage and a full cooling wait before cutting.

Why This Blondie Recipe Delivers a Chewy Center

The recipe is built around a dense bar: melted butter, a generous measure of brown sugar, and just enough flour to hold a slice. Gentle mixing and a cue-led bake preserve a soft center without relying on a wet middle.

• A measured base: The gram weights keep packing and scooping differences from changing the butter, sugar, and flour balance.
• Restrained aeration: A whisk and spatula combine the ingredients without an extended creaming stage.
• A deliberate finish: Baking until the center sets, then cooling fully, separates oven readiness from slicing readiness.

Why You’ll Love These Classic Blondies

Seven familiar ingredients and two hand tools make these approachable for a small home bake. The work is concentrated at the beginning, leaving time for other things while the pan bakes and cools.

There is no dough to portion or second tray to rotate, and the nine-square yield is convenient for sharing. Bake them ahead when you want dessert ready before guests arrive, rather than trying to squeeze cooling into the last few minutes.

The Science Behind Dense, Chewy Blondies

Blondie texture depends on moisture, the amount of air mixed into the batter, and how the flour and egg set during baking. Each of these has a practical consequence for this simple pan of bars.

Brown Sugar and Moisture

Brown sugar contributes moisture and a denser texture to cookie dough, as Iowa State University Extension explains in its guide to how brown sugar affects cookie texture. Here, keeping the brown sugar helps support the intended chew; replacing it with white sugar changes more than the color.

Melted Butter and a Low Rise

Melted butter combines with sugar without the air pockets created by creaming softened butter. Whisk to blend rather than to build volume, keeping the batter suited to a compact bar.

Flour, Mixing, and the Chewy Bite

Flour supplies structure, but extra flour can push the bars toward a dry, firm result. Once it meets the wet mixture, prolonged mixing also develops more gluten. Measure the flour carefully and stop folding when its dry streaks disappear.

Heat Sets the Center; Cooling Firms the Slice

During baking, the egg proteins and flour help the center hold together. Cooling then firms the baked slab for cutting. These are separate stages: cooling can improve a baked bar’s slice, but it cannot finish cooking liquid batter.

Ingredients for Classic Chocolate Chip Blondies

Use the seven ingredients below for the base batch. Measure before mixing, and pay particular attention to the butter temperature and flour weight.

Ingredient List

These quantities fill one 8 × 8-inch pan. All of the chocolate chips go into the batter; no extra topping portion is needed.

• 1/2 cup unsalted butter (113 g), melted and cooled until warm
• 1 cup packed light brown sugar (200 g)
• 1 large egg, at room temperature (about 50 g without shell)
• 2 teaspoons vanilla extract (10 ml)
• 1 cup all-purpose flour (120 g), spooned and leveled
• 1/2 teaspoon fine sea salt (about 3 g)
• 1/2 cup semisweet chocolate chips (85 g)

Choosing the Brown Sugar

Light brown sugar gives the bars a gentle molasses flavor. Choose a soft, fresh bag so hard lumps do not remain in the batter. Dark brown sugar can be used at the same 200 g weight for a stronger molasses flavor and darker color.

Preparing the Butter and Egg

Use unsalted butter and melt it without browning. Let it cool until warm before adding the room-temperature egg; hot butter can begin setting the egg instead of blending smoothly with it.

Measuring Flour and Fine Salt

A scale makes the 120 g flour measure easy to repeat. For the cup measure, spoon flour into the cup and level it without packing. Choose fine sea salt; coarse or kosher crystals do not give the same salt amount by teaspoon.

Choosing the Chocolate Chips

Semisweet chips balance the sweet brown-sugar base. A different chip type can be used at the same 85 g weight, with a corresponding change in sweetness and flavor. Fold in the full portion rather than adding an unmeasured handful on top.

For a sweeter chocolate flavor in a cookie instead of a bar, white chocolate chip cookies offer another way to enjoy that pairing.

The Pan and Tools for Evenly Baked Blondies

Pan size and material matter because they affect batter depth and the way the edges bake. A parchment sling makes it easier to lift the cooled slab without prying at its sides.

• 8 × 8-inch light-colored metal pan, at least 2 inches deep, and parchment sling
• Digital scale, measuring cups and measuring spoons
• Large heatproof mixing bowl and a microwave-safe butter-melting vessel or small saucepan
• Whisk and flexible spatula
• Wire rack, cutting board, sharp knife and toothpick

Before You Begin Baking Blondies

A few checks before mixing prevent interruptions once the egg and flour are in the bowl. Include cooling time in your plan, especially if the bars are for an event.

• Set out the 8 × 8-inch light-colored metal pan and parchment sling.
• Preheat a conventional oven to 350°F (175°C), with the rack in the middle.
• Have the egg at room temperature and the melted butter warm, not hot.
• Measure the flour and sugar, and break up any hard sugar lumps.
• Allow roughly 60–90 minutes after baking for cooling, with extra time if the slab is still warm.

What to Expect from These Chocolate Chip Blondies

Expect a thick, sticky batter that needs spreading into the corners. The finished bars are low-profile and dense, with golden edges, a soft set middle, and chocolate chips throughout. They have a modest rise rather than a tall cake-like crumb, and the center should be baked rather than raw cookie dough.

How to Make Blondies, Step by Step

Combine the wet ingredients first, fold in the flour and chips, and spread the batter evenly. Check the center as the bake approaches its finishing window, then leave the slab in its pan until completely cool.

1. Prepare the oven and pan

Preheat the oven to 350°F (175°C) in conventional mode and position the rack in the middle. Line the 8 × 8-inch metal pan with parchment across the base and sides, leaving an overhang for lifting.

What you should see: Paper sits flat against the base, with an accessible overhang on opposite sides.

2. Combine butter and brown sugar

Melt the butter gently in a suitable vessel or small saucepan without browning it. Whisk in the brown sugar until evenly combined. If the mixture is hot, let it cool until warm before continuing.

What you should see: A damp, slightly grainy mixture with evenly distributed sugar and no darkened butter solids.

3. Add egg and vanilla

Whisk in the egg and vanilla until the mixture is cohesive. Stop when the egg is incorporated; there is no need to whip the mixture into a pale foam.

What you should see: A smoother mixture with no separate streaks of egg.

4. Fold in flour, salt and chips

Add the flour and salt, then fold with a flexible spatula until the dry streaks disappear. Scrape the bottom of the bowl to catch flour pockets, and fold in all of the chocolate chips.

What you should see: Thick, sticky, spreadable batter with chips distributed throughout and no patches of dry flour.

5. Spread and bake

Transfer the batter to the pan and spread it into an even layer, including the corners. Bake on the middle rack, starting checks at 20 minutes. Allow approximately 20–30 minutes, using the edges, center, and a tester placed clear of a chocolate chip to judge readiness.

What you should see: Golden, set edges and a center that holds its surface without liquid movement. A toothpick in the baked center should carry moist crumbs rather than wet batter.

6. Cool and cut

Set the pan on a wire rack and cool completely before lifting out the slab. Allow roughly 60–90 minutes for planning, but wait longer if it is still warm. Transfer to a cutting board and cut three rows in each direction to make nine squares.

What you should see: The pan and slab are at room temperature, and each cut holds an edge. Wipe the sharp knife between cuts if chocolate collects on the blade.

How to Tell When Blondies Are Baked and Ready to Slice

Use the edges, center surface, and toothpick together. A smear of melted chocolate can make a baked center look wetter on the tester than it is, so check where the tester entered the batter.

Read the Edges, Center, and Tester

The tester is most useful when it passes through the blondie itself. Compare what it carries with the center’s appearance before deciding whether to remove the pan.

Tester result	Check beside it	What to do
Moist crumbs	Golden set edges; the center holds its surface without liquid movement	Remove the pan when the cues agree, then cool completely.
Dark chocolate smear	The tester may have passed through a chip	Retest nearby, clear of a chip, before changing the baking time.
Pale wet batter	The center may still show liquid movement	Continue baking and recheck. Cooling will not cook a raw center.

Wait Until the Slab Is Ready to Slice

Bake completion is not the same as cutting readiness. Keep the slab in its pan on the rack until both have reached room temperature, then lift it with the sling. If the middle is still warm, give it more time before cutting.

I learned with brownies that cutting a pan while it is still warm can leave the edges messy. That is why I let bars cool completely before cutting them into squares.

Expert Tips for Better Blondie Texture

Small choices help the edges and center bake more evenly and make the cooled squares easier to cut. Focus on the pan, the depth of the batter, and what your tester actually touches.

• Use the specified light-colored metal pan. Material and color affect heating, so matching the pan keeps the bake window more useful for the center and edges.
• Check butter temperature before adding the egg. Warm butter blends readily; very hot butter can set small bits of egg and leave the mixture uneven.
• Level the batter into the corners. A mound in the middle makes that area deeper, so an even layer reduces the chance of baked edges surrounding a slower center.
• Choose a clear tester path. Passing through chocolate can obscure the crumb result, so a nearby chip-free check gives a more useful reading.
• Wipe the blade between cuts. Chocolate and crumbs on the knife drag across the next edge; a clean blade leaves neater squares.

Common Blondie Mistakes and How to Prevent Them

An unwanted texture often points to measurement, heat, or slicing. Some issues can be prevented in the next batch, while others simply need more time before you continue.

Mistake	Symptom	Likely cause	Prevention or realistic recovery
Adding too much flour	Dry, firm bars	A packed or heaped flour cup	Weigh 120 g, or spoon and level. Extra flour cannot be removed after mixing.
Overbaking	Dry edges and a firm center	Waiting for a completely clean tester	Start checking at 20 minutes. Serve dry bars with an optional accompaniment; added baking time cannot be reversed.
Changing the pan	Uneven timing or a different bar depth	Different dimensions, color, or material	Use the specified pan. Do not carry the same bake window unchanged to a different setup.
Adding egg to hot butter	Small set egg pieces or an uneven mixture	Butter was still too hot	Let the butter-sugar mixture become warm first. If the egg has visibly cooked, restart the wet mixture.
Overmixing after flour	A tougher bite	Working the hydrated flour too long	Fold only until dry streaks disappear; stop once the chips are distributed.
Cutting while warm	Ragged edges or a slab that bends	The baked bars have not firmed during cooling	Stop slicing and let the remaining slab cool completely before continuing.

Beautiful Ways to Serve Chocolate Chip Blondies

The fully cooled square is the starting point for serving. Keep accompaniments optional so the brown-sugar and chocolate flavor can stand on its own.

A Plain Square at Room Temperature

Place a square on a small plate with the cut face visible. Room temperature lets the dense crumb feel softer than a chilled bar, without adding a topping.

With Vanilla Ice Cream

Add a scoop of vanilla ice cream beside a cooled square for a simple plated dessert. The cold, creamy accompaniment contrasts with the chewy bar; add it just before serving.

With Coffee or Tea

Serve a plain square with coffee or black tea when you want a small afternoon treat. An unsweetened drink balances the bar’s brown sugar and chocolate without requiring another dessert component.

On a Dessert Plate to Share

Arrange the nine cooled squares in a single layer or slightly overlapping rows. Keeping the cut edges visible makes them easy to pick up and avoids compressing soft pieces beneath a tall stack.

Keeping Blondies Soft: Storage, Freezing, and Make-Ahead

Let the blondies cool completely before sealing them. Trapped warmth can create condensation, while exposure to air gradually dries the cut edges.

Storing at Room Temperature

Store in an airtight container in a cool room for up to three days. Separate layers with parchment if needed. In a warm room, refrigeration is an option; let a chilled square return to room temperature for a softer texture.

Freezing and Thawing Individual Squares

Wrap completely cooled squares individually, then place them in a sealed freezer container. Use within about three months for best quality. Thaw wrapped at room temperature until fully thawed before serving.

Baking Ahead and Packing for Sharing

Bake early enough to finish cooling before packing, or bake the day before and store airtight. For transport, use a snug container and parchment between layers so the squares do not slide into each other.

Questions About Baking and Storing Blondies

Pan changes affect batter depth and timing. If you need a different batch size, keep those changes separate from the measurements for this 8-inch pan.

Can I double this recipe?

For more squares, two separate 8 × 8-inch batches keep the batter depth consistent. Check each pan on its own. A doubled batch in a 9 × 13-inch pan has a different depth, so do not assume the same baking time.

Can I use a 9-inch square pan or a glass pan?

The 9-inch pan spreads the batter more thinly, while glass changes how the pan heats. For the result and timing described here, use the 8 × 8-inch light-colored metal pan. A different setup needs its own timing checks.
