Ingredients

  • FOR THE CAKE:
  • 1-3/4 cup All-purpose Flour
  • 2 cups Sugar
  • 3/4 cups Cocoa Powder
  • 2 teaspoons Baking Soda
  • 1 teaspoon Baking Powder
  • 1 teaspoon Salt
  • 2 whole Eggs
  • 1 cup Strong Black Coffee, Cooled (for 1 Cup I Use 2 Teaspoons Instant Espresso In 1 Cup Boiling Water)
  • 1 cup Buttermilk (or Make Your Own Sour Milk By Mixing 1 Tablespoon Vinegar In 1 Cup Regular Milk)
  • 1/2 cups Vegetable Oil
  • 2 teaspoons Pure Vanilla Extract
  • FOR THE FROSTING:
  • 1/2 cups Butter
  • 2/3 cups Creamy Peanut Butter
  • 1 teaspoon Pure Vanilla Extract
  • 1/4 teaspoons Salt
  • 2 cups Powdered Sugar (add Up To 1 More Cup, Depending On Taste)
  • 1/3 cups Milk

Method

  • For the cake:
  • Preheat oven to 350 F.
  • Combine flour, sugar, cocoa powder, baking soda, baking powder and salt in a large mixing bowl. Add eggs, coffee, buttermilk, vegetable oil and vanilla, and beat at medium speed for 2 minutes. Batter will be thin.
  • Pour into a greased and floured 13"x9" pan and bake 35-40 minutes (or use two 9" round pans and bake for 30-35 minutes for a layer cake).
  • For the frosting:
  • Put the butter into a large microwave safe bowl. Melt butter in the microwave, heating for 30 seconds at a time until melted. Then stir in peanut butter until well combined.
  • Stir in vanilla and salt. Alternately beat in powdered sugar and milk with an electric mixer, and taste when it begins to get thick and a spreadable consistency. Add up to 3 cups of powdered sugar if you prefer a sweeter frosting.
  • Spread frosting onto cooled cake and serve.
