directions

  • Preheat the oven to 350 degrees F. Butter and/or line 2 (8-inch) round cake pans. Line with parchment paper, then butter and flour the pans.
  • Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl of an electric mixer fitted with a paddle attachment and mix on low speed until combined. In another bowl, combine the buttermilk, oil, eggs, and vanilla.
  • With the mixer on low speed, slowly add the wet ingredients to the dry. With mixer still on low, add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula. Pour the batter into the prepared pans and bake for 35 to 40 minutes, until a cake tester comes out clean. Cool in the pans for 30 minutes, then turn them out onto a cooling rack and cool completely.
  • Place 1 layer, flat side up, on a flat plate or cake pedestal. With a knife or offset spatula, spread the top with frosting. Place the second layer on top, rounded side up, and spread the frosting evenly on the top and sides of the cake.
  • Chop up your peanut butter cups and stick them all over the cake!
  • Chocolate Frosting.
  • 6 ounces good semisweet chocolate.
  • 2 sticks (1 cup) unsalted butter, at room temperature.
  • 1 extra-large egg yolk, at room temperature.
  • 1 teaspoon pure vanilla extract.
  • 1 1/4 cups sifted confectioners’ sugar.
  • 1 tablespoon instant coffee powder.
  • 2 teaspoons water.
  • Chop the chocolate and place it in a heat-proof bowl set over a pan of simmering water. Stir until just melted and set aside until cooled to room temperature.
  • In the bowl of an electric mixer fitted with a paddle attachment, beat the butter on medium-high speed until light yellow and fluffy, about 3 minutes. Add the egg yolk and vanilla and continue beating for 3 minutes.
  • Turn the mixer to low, gradually add the confectioners’ sugar, then beat at medium speed, scraping down the bowl as necessary, until smooth and creamy.
  • Dissolve the coffee powder in 2 teaspoons of the hottest tap water. On low speed, add the chocolate and coffee to the butter mixture and mix until blended. Don’t whip! Spread immediately on the cooled cake.

  1. I made this cake for my husband and son for Valentine's Day. Today. I followed the instructions exactly but as I was getting the ingredients together for the frosting, I had a brilliant idea. I subbed 1/2 cup creamy peanut butter for 1 stick of butter. OMG. The boys RAVED over this cake. I let them have the frosting since I had a bit left over and they were chomping at the bit to get to that cake after the frosting. It had just a small bite of peanut butter in the taste. Exactly what it needed to top off the rich chocolate cake. AMAZING. I'm sure this will be a cake I make again!
