How To Make

Creating this legendary cake is easier than you think once you follow the technique carefully. Let me guide you through making perfect Texas Sheet Cake every single time you bake it.

Prepare the Pan

Preheat your oven to 175 degrees Celsius or 350 degrees Fahrenheit. Make sure the oven is fully preheated before baking.

Grease an 18 by 13 inch jelly roll pan generously with nonstick cooking spray, Use the larger pan not a 9 by 13 inch pan to achieve the signature thin profile that defines this cake.

Make the Chocolate Mixture

In a medium saucepan over medium heat, combine the water, butter, and unsweetened cocoa powder. Bring the mixture to a boil, stirring occasionally to ensure even heating.

Mix Dry Ingredients

Meanwhile, in a large bowl whisk together the flour, sugar, baking soda, and salt. Make sure everything is fully combined with no lumps of baking soda.

Combine Wet Ingredients

In a separate small bowl, whisk together the sour cream, eggs, and vanilla extract until smooth. Mix just until blended with no egg streaks visible.

Make the Batter

Add the sour cream and egg mixture to the flour mixture and stir until combined. Mix gently until no dry flour remains.

Once the chocolate mixture in the saucepan reaches a boil, remove it from the heat immediately. Pour it into the batter and mix until fully combined with no lumps remaining. The batter will be thin and pourable, which is completely correct.

Bake the Cake

Pour the batter into the prepared pan and smooth it with a spatula. Create a perfectly even layer all the way to the edges of the pan.

Bake for 15 to 20 minutes until the cake is set. A toothpick inserted in the center should come out clean. At 15 minutes start checking so you don’t overbake this delicate cake.

Make the Frosting

When the cake is about halfway through baking, start the frosting. Add the milk, cocoa powder, and butter to a small saucepan over medium heat.

Bring the mixture to a boil, stirring constantly for frosting. This takes about 3 to 5 minutes of continuous stirring.

Once boiling, remove from heat immediately and stir in the powdered sugar. Beat with a handheld electric mixer to eliminate any lumps and create smooth glossy frosting. Beat for about 30 seconds until perfectly smooth.

Apply the Frosting

As soon as the cake comes out of the oven, pour the hot frosting directly over the hot cake. Timing is absolutely everything for that iconic fudgy layer.

Use a spatula to spread it quickly and evenly all the way to the edges before it begins to set. Work fast because the frosting sets quickly once it hits the air.

Allow the frosting to set for about 10 minutes before slicing and serving your Texas Sheet Cake. This gives it time to firm up into that iconic crackly fudgy layer.

How to Serve

This Texas Sheet Cake is perfect for potlucks, family gatherings, birthdays, church events, celebrations, or any time you need to feed a large crowd with incredible dessert. Serve at room temperature for best texture and flavor. The cake slices beautifully to show the thin moist crumb and fudgy frosting layer. Pair with cold milk, hot coffee, or vanilla ice cream for perfect combination. Store covered at room temperature for up to 3 days. The frosting acts as a seal keeping the cake underneath moist so refrigeration is not recommended. This makes 15 generous servings perfect for large celebrations.

Expert Tips

Common Questions

Why pour hot frosting on hot cake?

Hot frosting poured on hot cake soaks slightly into the surface and sets into that iconic thin fudgy crackly layer that defines Texas Sheet Cake. This is the key technique that makes this cake different from modern versions. Letting either one cool first ruins the texture completely and creates dense frosting instead.

Can I make Texas Sheet Cake ahead?

Yes! You can bake Texas Sheet Cake up to 2 days ahead and store it covered. Make the frosting fresh and apply it while both are hot. The cake improves as flavors meld together overnight in your Texas Sheet Cake.

Can I freeze Texas Sheet Cake?

Yes! Wrap unfrosted cake tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. Apply frosting after thawing for best results on your Texas Sheet Cake. The frosting doesn’t freeze well on the cake.

What if my cake is dry?

Dryness usually means overbaking for your Texas Sheet Cake. Start checking at 15 minutes and pull cake when just set. Sour cream is essential for moisture so don’t skip it in your Texas Sheet Cake recipe.
