8 to 10 servings


  1. Heat oven to 350 degrees. Butter two 8-inch cake pans, and line base of each with parchment paper. In food processor, combine 1/2 cup walnut pieces and sugar. Process to a fine powder. Add butter, flour, baking powder and eggs. Process to a smooth batter.
  2. Add 2 tablespoons milk to coffee mixture and pour this down feed tube with motor running. Mixture should be just soft enough to drop from a spoon; if not, add more milk. Divide cake batter between two pans. Bake until risen and springy to touch, about 25 minutes. Cool on a rack for 10 minutes, then remove from pan and place on rack. Remove parchment paper. Cool completely.
  3. For frosting: Place confectioners’ sugar in food processor and pulse until lump-free. Add butter and process until smooth. Add coffee mixture down feed tube and pulse until well blended.
  4. Place one cake upside down on a plate or cake stand. Spread with about half the frosting. Place second cake right side up on frosting, and cover top and sides in a swirly pattern. Place a walnut half in center of cake, and gently press remaining halves into top of cake, around the edge.
