  • 1 tsp salt
  • 1 cup buttermilk
  • 1 cup freshly made coffee
  • 5 tbsp vegetable oil
  • 1 1/2 tsp vanilla extract
Coffe Buttercream
  • 1 cup softened butter
  • 4 cups powdered sugar
  • 3 tbsp instant coffee granules
  • 1 1/2 tbsp boiling water
  • Handful of chopped Reese's for filling in between layers

For the Chocolate Cake
  1. 1. Preheat oven to 350 degrees. Butter two 8-inch cake rounds and dust with flour, tapping out excess. 

  2. 2. Mix together all dry ingredients: flour, sugar, cocoa, baking soda, baking powder and salt in a stand mixer using a low speed until combined. 

  3. 3. Add eggs, buttermilk, coffee, oil and vanilla. Beat on a medium speed until smooth, two to three minutes. 

  4. 4. Divide batter evenly among the two pans. 

  5. 5. Bake for 30-35 minutes until a toothpick inserted into the center comes out clean. 

  6. 6. Let cakes cool for 10 minutes and turn out onto wire racks. 

  7. 7. Once cooled, slice off the top of the cake and cover lightly in a simple syrup. Wrap in cling wrap and freeze until cake is firm, about 45 minutes. 

Coffee Buttercream
  1. 1. Mix the instant coffee with boiling water and set aside to cool. 

  2. 2. Cut the buter into cubes and beat on a low-medium speed until soft. Gradually add in icing sugar and beat until fully combined. 

  3. 3. Add in vanilla extract, followed by the coffee one teaspoon at a time. Be sure to mix fully before adding more. 

  4. 4. If your buttercream is stiff, add in a little milk.

Hershey Chocolate Ganache
  1. 1. Break up your Hershey bars and place bits into a medium bowl. 

  2. 2. Heat the cream in a sauce over medium-high heat, until it begins to simmer. Remove from heat and pour over chocolate. 

  3. 3. Let sit for about five minutes and stir until completely melted and smooth. Stir in corn syrup.

  4. Note: The longer you let this sit, the thicker it will be. 

To Decorate
  1. 1. Cut up Reese's into small pieces. Place in bowl and set aside. Fill your layers with buttercream and Reese's and cover entire cake with chocolate ganache. Decorate to your liking!

  2. Enjoy!
