The Most Amazing Texas Sheet Cake

Step 1

Preheat oven to 350 degrees. Lightly grease a 13x18 inch baking sheet.

Step 2

In a large mixing bowl stir together flour, sugar, cocoa, baking soda, and salt.

Step 3

Add eggs, buttermilk, warm water, oil, and vanilla. Whisk until combined and batter is smooth. This should take just a couple of minutes. Pour batter into prepared baking sheet.

Step 4

Bake for 20-25 minutes until a toothpick inserted into the center comes out clean. Cool on a wire rack for 15 minutes before frosting.

Step 5

Melt butter in a medium-sized saucepan over low heat. Whisk in cocoa powder, then pour in buttermilk. Increase heat to medium high and bring to a simmer, whisking constantly.

Step 6

Once the mixture is simmering, remove from the heat and whisk in powdered sugar and vanilla until smooth. Pour over cake to cover. Use a rubber spatula to smooth out and spread if needed. Sprinkle on chopped pecans. Let the cake and frosting cool completely before cutting and serving.
