What Is Texas Sheet Cake?

Texas Sheet Cake is a thin, moist chocolate cake baked in a sheet pan. It’s topped with a warm, poured-on frosting that soaks into the cake, making it extra rich. No stacking, no fuss—just a giant slab of happiness.

Ingredients

For the Cake

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1 cup unsalted butter
• 1 cup water
• ¼ cup cocoa powder
• 2 large eggs
• ½ cup sour cream
• 1 teaspoon vanilla extract

For the Frosting

• ½ cup unsalted butter
• ¼ cup cocoa powder
• 6 tablespoons milk
• 1 teaspoon vanilla extract
• 3 ½ cups powdered sugar
• ½ cup chopped pecans (optional)

How to Make Texas Sheet Cake

Step 1

Preheat your oven to 350°F. Grease a 12×17-inch sheet pan.

Step 2

In a large bowl, whisk flour, sugar, baking soda, and salt.

Step 3

In a saucepan, melt butter with water and cocoa powder. Bring to a boil, then remove from heat.

Step 4

Pour the chocolate mixture into the dry ingredients. Mix well.

Step 5

Add eggs, sour cream, and vanilla. Stir until smooth.

Step 6

Pour the batter into the sheet pan. Bake for 18-20 minutes, or until a toothpick comes out clean.

Step 7

While the cake bakes, make the frosting. Melt butter with cocoa powder and milk in a saucepan. Bring to a boil, then remove from heat.

Step 8

Whisk in vanilla and powdered sugar until smooth. Stir in pecans if using.

Step 9

Pour the warm frosting over the hot cake. Spread evenly. Let cool before slicing.

Can You Freeze Texas Sheet Cake?

Yes! Texas Sheet Cake freezes well, with a few tips to keep it fresh:

Best Way to Freeze:

1. Cool Completely – Let the frosted cake cool fully (so the frosting sets).
2. Slice First – Cut into portions for easy grab-and-thaw servings.
3. Wrap Tightly –
   • Option 1: Cling wrap (press directly onto frosting to prevent ice crystals).
   • Option 2: Aluminum foil + airtight container for extra protection.
4. Freeze Flat – Lay slices in a single layer to avoid squishing.

How Long?

• Up to 3 months (after that, quality declines).

Thawing:

• Overnight in the fridge (best for texture).
• Room temp (1-2 hours) if you’re impatient.
• Microwave? Only if desperate—10-second bursts!

Pro Tip: Freeze without nuts if possible—they get soggy.

Freeze now, enjoy later… because chocolate emergencies happen! 🍫❄️

Final Tip

This cake disappears fast. Hide a piece for yourself—trust us.

Now go forth and bake the biggest, chocolatiest cake Texas would approve of! 🤠🍫
