Ingredients

CAKE

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup buttermilk
  • 1 cup warm water
  • 1/3 cup vegetable oil
  • 1 teaspoon vanilla extract

FROSTING

  • 1/2 cup salted butter
  • 1/3 cup unsweetened cocoa powder
  • 1/3 cup buttermilk
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 cup chopped pecans or walnuts

Instructions

FOR THE CAKE

  • Preheat oven to 350 degrees. Lightly grease a 13x18 inch baking sheet.
  • In a large mixing bowl stir together flour, sugar, cocoa, baking soda, and salt.
  • 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.
  • 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. 

FOR THE FROSTING

  • 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. 
  • 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.
