Why This Recipe Works
This Texas Sheet Cake recipe isn’t just easy; it’s engineered for success. Here’s why it consistently delivers a perfect cake:
- Melted Butter and Cocoa: Melting the butter and cocoa together right at the start infuses the cake with a deep, rich chocolate flavor that permeates every crumb. This crucial step also helps prevent the cocoa from clumping, ensuring a smooth and even batter.
- Buttermilk Power: Buttermilk is the secret ingredient to a supremely moist and tender cake. Its acidity tenderizes the gluten in the flour, resulting in a delicate crumb that practically melts in your mouth.
- Boiling Frosting: The hot frosting, poured directly onto the warm cake, creates a unique texture. It seeps into the cake’s surface, creating a fudgy, almost brownie-like top layer that’s simply irresistible. The heat also helps the frosting set evenly and quickly.
- One-Pan Wonder: Baking and frosting the cake in the same sheet pan minimizes cleanup and makes serving a breeze. Plus, the large surface area allows for even baking and maximum frosting coverage.
- Simple Ingredients, Big Flavor: We focus on using common pantry staples, proving that you don’t need fancy ingredients to create a truly exceptional dessert.

Ingredients
- For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1/4 teaspoon salt
- 1 teaspoon baking soda
- 1 cup (2 sticks) unsalted butter
- 1/4 cup unsweetened cocoa powder
- 1 cup water
- 1/2 cup buttermilk
- 2 large eggs, lightly beaten
- 1 teaspoon vanilla extract
- For the Frosting:
- 1 cup (2 sticks) unsalted butter
- 1/4 cup unsweetened cocoa powder
- 6 tablespoons milk
- 3 3/4 cups powdered sugar
- 1 teaspoon vanilla extract
- 1 cup chopped pecans or walnuts (optional)

Instructions
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 13×18 inch sheet pan. This is crucial to prevent sticking.
- Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, salt, and baking soda. Make sure everything is evenly distributed.
- Melt Butter and Cocoa: In a medium saucepan, melt the butter over medium heat. Stir in the cocoa powder and water. Bring to a simmer, stirring constantly, until smooth. This mixture should be hot.
- Combine Wet and Dry: Pour the hot butter-cocoa mixture over the dry ingredients in the large bowl. Mix until just combined. Be careful not to overmix.
- Add Buttermilk, Eggs, and Vanilla: Stir in the buttermilk, beaten eggs, and vanilla extract. Mix until the batter is smooth. The batter will be thin, which is perfectly normal.
- Bake the Cake: Pour the batter into the prepared sheet pan and spread evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Prepare the Frosting (While Cake Bakes): While the cake is baking, prepare the frosting. In a medium saucepan, melt the butter over medium heat. Stir in the cocoa powder and milk. Bring to a simmer, stirring constantly, until smooth.
- Add Powdered Sugar and Vanilla: Remove the saucepan from the heat and whisk in the powdered sugar and vanilla extract until smooth and creamy.
- Add Nuts (Optional): If using, stir in the chopped pecans or walnuts.
- Frost the Cake: As soon as the cake comes out of the oven, pour the hot frosting evenly over the warm cake. Spread with a spatula to ensure complete coverage.
- Let Cool: Let the cake cool completely before cutting and serving. This allows the frosting to set and the flavors to meld together.
Tips for Success
Here are a few extra tips to ensure your Texas Sheet Cake is a resounding success:
- Don’t Overbake: Overbaking will result in a dry cake. Start checking for doneness around 20 minutes. The cake is ready when a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
- Use Good Quality Cocoa: The quality of your cocoa powder will significantly impact the flavor of the cake and frosting. Use a good quality unsweetened cocoa powder for the best results.
- Measure Accurately: Accurate measurements are crucial for baking. Use measuring cups and spoons specifically designed for baking.
- Don’t Skip the Buttermilk: Buttermilk is essential for the cake’s moist and tender texture. If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of white vinegar or lemon juice to 1/2 cup of milk. Let it sit for 5 minutes before using.
- Adjust Sweetness: If you prefer a less sweet frosting, reduce the amount of powdered sugar by 1/4 to 1/2 cup.
- Variations: Feel free to experiment with different flavors. Add a teaspoon of cinnamon to the cake batter or frosting for a warm, spicy twist. You can also use different types of nuts, such as almonds or hazelnuts.
