Cake Ingredients

  • 1 3/4 cups all-purpose flour
  • 2 cups white sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 2 eggs
  • 1 cup strong brewed coffee
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 1 teaspoon vanilla extract

Peppermint Filling

  • 1/2 cup butter room temperature
  • 3 cups Powdered sugar
  • 1/2 cup whipping cream
  • 1 teaspoon vanilla extract
  • 1 1/2 teaspoon peppermint extract

Chocolate Ganache

  • 1 12oz bag semisweet chocolate chips
  • 1 cup whipping cream
  • 3 tablespoons butter



  1. Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9 inch round cake pans or one 9x13 inch pan.
  2. In a large bowl combine flour, sugar, cocoa, baking soda, baking powder and salt. Make a well in the centre.
  3. Add eggs, coffee, buttermilk, oil and vanilla. Beat for 2 minutes on medium speed. The batter will be thin. Pour into prepared pans.
  4. Bake at 350 degrees F (175 degrees C) for 30 to 40 minutes, or until a toothpick inserted into the center of the cake comes out clean. Cool for 10 minutes, then remove from pans and finish cooling on a wire rack. Fill and frost as desired.

Peppermint Filling

  1.  Beat butter at medium speed with an electric mixer until creamy, about 1 minute. Add powdered sugar and mix on medium speed for 1-2 minutes. 

  2. Pour in whipping cream, vanilla and peppermint extract. Mix on high for 3-4 minutes until fluffy. If the filling is too thick, add a couple more teaspoons of heavy cream. 
  3. When cake has cooled, frost the bottom cake layer with the frosting, leaving 1/2 border around the edge and place in the refrigerator to set, about 30 minutes.

Chocolate Ganache

  1. Microwave chocolate chips and whipping cream in a 2-quart microwave-safe bowl at MEDIUM (50% power) 2 1/2 to 3 minutes or until chocolate begins to melt.

  2. Whisk until chocolate melts and the mixture is smooth. Whisk in butter; let stand 20 minutes. Beat at medium speed with an electric mixer 5 to 8 minutes or until mixture forms soft peaks. The ganache should have a soft whipped icing consistency that does not sag off your spatula.
  3. Top the peppermint frosting with the top cake layer (top of the cake layer facing down), and frost entire cake with ganache.

Recipe Notes

The cake recipe is originally from the Hershey Cocoa can from my childhood, so in the 80s, it is still the best and easiest cake I make.
