Ingredients
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup unsalted butter
- 1 cup water
- 1/4 cup unsweetened cocoa powder
- 2 large eggs
- 1/2 cup buttermilk
- 1 teaspoon vanilla extract
For the Fudgy Icing:
- 1/2 cup unsalted butter
- 1/4 cup unsweetened cocoa powder
- 6 tablespoons milk
- 1 teaspoon vanilla extract
- 3 1/2 cups powdered sugar
- 1 cup chopped pecans or walnuts (optional)
Step-by-Step Instructions
Preheat your oven to 350°F (175°C). Grease a 15x10x1-inch jelly roll pan or a similar sized baking sheet with sides.
In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt. Set aside.
In a medium saucepan, combine the butter, water, and cocoa powder. Heat over medium heat, stirring occasionally, until the butter melts and the mixture comes to a gentle boil. Remove from heat.
Pour the hot cocoa mixture over the dry ingredients and stir until just combined. The batter will be thick.
In a small bowl, whisk together the eggs, buttermilk, and vanilla extract. Add this to the batter and mix until smooth and well combined.
Pour the batter into the prepared pan and spread it evenly. Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean.
While the cake is baking, prepare the icing. In a medium saucepan, combine the butter, cocoa powder, and milk. Heat over medium heat, stirring constantly, until the butter melts and the mixture comes to a boil. Remove from heat.
Whisk in the vanilla extract, then gradually add the powdered sugar, stirring until smooth and glossy. If using nuts, stir them in at this point.
As soon as the cake comes out of the oven, pour the warm icing over the hot cake, spreading it evenly with a spatula. The icing will set as the cake cools.
Allow the cake to cool completely before cutting into squares and serving.
Expert Tips
For the best texture, make sure to measure your flour correctly by spooning it into the measuring cup and leveling it off. Too much flour can make the cake dry.
If you don’t have buttermilk, you can make a quick substitute by adding 1 1/2 teaspoons of lemon juice or vinegar to 1/2 cup of regular milk and letting it sit for 5 minutes.
The warm icing poured over the hot cake creates that signature crackly finish that Texas sheet cake is known for. Don’t skip this step!
This cake stores well at room temperature for up to 3 days when covered tightly. It also freezes beautifully for up to 3 months.
For an extra special touch, try adding a teaspoon of instant coffee granules to the cocoa mixture – it enhances the chocolate flavor without making the cake taste like coffee.

Frequently Asked Questions
Can I make this cake ahead of time?
Absolutely! This cake actually tastes even better the next day as the flavors have more time to develop. Just make sure to store it covered at room temperature.
Can I use a different pan size?
You can use a 9×13-inch pan, but you’ll need to increase the baking time to 25-30 minutes. The cake will be thicker, so adjust the icing quantity if needed.
What’s the secret to the moist texture?
The combination of buttermilk and the hot cocoa mixture creates a chemical reaction that results in an exceptionally moist and tender crumb.
Can I make this cake without nuts?
Yes, the nuts are optional. The icing will still be delicious without them, or you could substitute with sprinkles or chocolate chips for decoration.
