Grandma's Chocolate Texas Sheet Cake

Ingredients

• 1 cup salted butter
• 1 cup water
• 3 tablespoons cocoa powder
• 2 cups all-purpose flour
• 2 cups white sugar
• 0.5 teaspoons salt
• 0.5 cups buttermilk
• 2 large eggs
• 1 teaspoon baking soda
• 1 teaspoon vanilla extract

Instructions

1. 1

   Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 10x15-inch cake pan.

2. 2

   Prepare the cake: Combine butter, water, and cocoa powder in a saucepan over medium heat. Cook until butter has melted and mixture comes to a boil. Remove from the heat and cool slightly.

3. 3

   Meanwhile, mix flour, sugar, and salt together in a large bowl. Beat buttermilk, eggs, baking soda, and vanilla extract together in a separate bowl.

4. 4

   Add melted butter mixture to flour mixture, then add buttermilk-egg mixture and beat until thoroughly combined. Pour into the prepared cake pan.

5. 5

   Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 20 minutes. Remove cake from the oven and cool on a wire rack for 5 minutes.

6. 6

   While the cake bakes, make the frosting: Combine butter, milk, cocoa powder, and vanilla extract in a saucepan over medium heat. Stir until butter melts, then stir in powdered sugar.

7. 7

   Spread frosting over the warm cake.
