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 unsweetened cocoa powder
- 2 large eggs
- ½ cup buttermilk
- 1 teaspoon vanilla extract
For the Fudgy Icing:
- ½ cup unsalted butter
- ¼ cup milk
- ¼ cup unsweetened cocoa powder
- 3 ½ cups powdered sugar
- 1 teaspoon vanilla extract
- ½ cup chopped walnuts or pecans (optional)
Step-by-Step Instructions
Preheat your oven to 375°F (190°C). Grease a 15×10-inch baking sheet or jelly roll pan.
In a large mixing bowl, whisk together flour, sugar, baking soda, and salt. Set aside.
In a medium saucepan, combine butter, water, and cocoa powder. Heat over medium heat until butter melts and mixture comes to a boil. Remove from heat and pour this hot mixture into the dry ingredients. Stir until well combined.
In a separate bowl, whisk together eggs, buttermilk, and vanilla extract. Add this to the chocolate mixture and stir until smooth. Pour the batter into the prepared baking sheet and spread evenly.
Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean. While the cake bakes, prepare the icing.
For the icing, combine butter, milk, and cocoa powder in a saucepan. Bring to a boil, then remove from heat. Whisk in powdered sugar and vanilla until smooth. Stir in nuts if using.
Pour the warm icing over the hot cake immediately after it comes out of the oven. Spread evenly and allow to cool completely before slicing.
Expert Tips
For the best results, use room temperature ingredients – this helps create a smoother batter and more even baking. Don’t overmix the batter once you add the wet ingredients to avoid developing gluten and making the cake tough. The secret to that signature Texas sheet cake texture is pouring the warm icing over the hot cake – this creates a fudgy layer that melts into the cake.
This recipe pairs beautifully with other easy chocolate sheet cakes for larger gatherings. If you’re looking for more sheet pan desserts, try our dark chocolate sheet cake for a slightly less sweet alternative.
