• 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

Step 2: In a large mixing bowl, whisk together flour, sugar, baking soda, and salt. Set aside.

Step 6: Pour the batter into the prepared pan and spread evenly. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: While the cake bakes, prepare the icing. In a saucepan, combine butter, cocoa powder, and milk. Bring to a boil, then remove from heat.

Step 8: Whisk in vanilla extract and powdered sugar until smooth. Stir in nuts if using.

Step 9: Pour the warm icing over the hot cake as soon as it comes out of the oven. Spread evenly with a spatula.

Step 10: Allow the cake to cool completely before cutting into squares and serving.

Expert Tips

Perfect Texture: Don’t overmix the batter – just combine until the ingredients are incorporated. Overmixing can make the cake tough.

Timing is Key: Pour the icing over the hot cake so it soaks in slightly, creating that signature Texas sheet cake texture.

Buttermilk Substitute: If you don’t have buttermilk, mix 1/2 cup milk with 1 1/2 teaspoons lemon juice or vinegar and let it sit for 5 minutes.

Storage: This cake keeps well at room temperature for 2-3 days. Cover tightly to maintain freshness. For longer storage, refrigerate for up to a week.
