Ingredients

Cake:
  • 2 cups all purpose flour
  • 2 cups granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon vanilla extract

Instructions

    Cup of Yum
  1. Preheat oven to 350 degrees. Spray a 13x9 inch baking pan with cooking spray. In a large bowl, combine flour, sugar, cocoa powder, salt, baking soda, and baking powder. Mix well.
  2. Add in vanilla, eggs, buttermilk, and vegetable oil mixing until smooth. Pour in hot water and mix well. Batter will be very thin.
  3. Pour batter into prepared pan. Bake in preheated oven for 32-36 minutes, or until a toothpick inserted in center comes out clean. Allow to cool completely on a wire rack.
  4. While cake is cooling, prepare frosting. Combine softened butter, powedered sugar, cocoa powder, vanilla extract, and milk in a large bowl and beat over medium speed with an electric mixer until frosting is nice and creamy. Add more milk or powdered sugar until desired consistency is reached.
  5. Spread frosting evenly over top of the completely cooled cake. Slice and enjoy! Cake can be kept at room temperature for up to 3 days.

Notes

  • *Homemade buttermilk is really simple and quick to make if you don't have any on hand. All you need is plain white vinegar and regular milk, preferably whole or 2%. Simply add 1 Tablespoon of white vinegar to a liquid measuring cup and add enough milk to reach the 1 cup line. Stir, then allow the mixture to sit undisturbed for 5 minutes before adding to the recipe.
