  • 2 eggs
  • 1/2 cup oil

  • 1 tsp espresso powder
  • 1 1/4 cup butter softened 2 1/2 sticks
  • 1/8 tsp salt
  • 5 cups powdered sugar

Instructions

Cake

  • Preheat the oven to 350 degrees. Line and oil 3 8-inch cake pans. Place the Guiness in a small pot and reduce to 1/2 cup. Keep hot until needed.
  • Combine all the dry ingredients in a bowl. Mix the eggs and oil together. Add the yogurt, vanilla, and buttermilk to the egg mixture. Stir the egg mixture into the dry ingredients and add the hot beer reduction. Stir until smooth. Divide the batter evenly between the 3 pans (1 3/4 cup batter per pan). Bake for 20 minutes. Cool completely before adding ganache.

Soak

  • Once the cakes have cooled, brush each layer with Jameson.

Ganache

  • Bring the cream to a simmer. Remove it from the heat and stir in the chopped chocolate. When the chocolate is smooth stir in the Jameson. Allow to cool to room temperature then divide the ganache between two layers of cake. Smooth over the top and place in the freezer or refrigerator until set.

Buttercream

  • Combine the Bailey's and the espresso powder and set aside. Cream the butter until smooth. Add the salt and sugar and beat until the sugar is incorporated. Mix in the Bailey's mixture. Buttercream should be smooth and spreadable. Keep at room temperature until ready to use.
  • Remove the cake layers from the refrigerator or freezer and spread 1/3 cup of frosting over the ganache. Place one frosted layer on a cake plate and top with the other frosted layer. Top with the unfrosted cake layer and gently press. Ice the cake with the remaining frosting. Cut and serve.
