    15 servings


  • 3/4 cup butter, softened
  • 1-1/2 cups sugar, divided
  • 4 large eggs, room temperature, separated
  • 1 cup hot mashed potatoes (without milk or butter)
  • 1-1/2 cups all-purpose flour
  • 1/2 cup baking cocoa
  • 2 teaspoons baking powder
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1/2 teaspoon ground nutmeg
  • 1/4 teaspoon ground cloves
  • 1 cup milk
  • 1 teaspoon vanilla extract
  • 1 cup chopped nuts
  • 1-1/2 cups sugar
  • 2 large egg whites
  • 1/3 cup water
  • 2 teaspoons light corn syrup
  • 1/8 teaspoon salt
  • 1 teaspoon vanilla extract


  • In a large bowl, cream butter and 1 cup sugar. Add egg yolks; beat well. Add potatoes and mix thoroughly. Combine the flour, cocoa, baking powder, cinnamon, salt, nutmeg and cloves; add to creamed mixture alternately with milk, beating just until combined. Stir in vanilla and nuts.
  • In a small bowl, beat egg whites until foamy. Gradually add remaining sugar; beat until stiff peaks form. Fold into batter. Pour into a greased and floured 13-in. x 9-in. baking pan. Bake at 350° for 40-45 minutes or until a toothpick comes out clean. Cool on a wire rack.
  • In a small heavy saucepan, combine the sugar, egg whites, water, corn syrup and salt. Beat on low speed for 1 minute. Place pan over low heat; continue beating on low until a thermometer reads 160°.
  • Transfer to a bowl. Add vanilla; beat on high until stiff glossy peaks form, about 7 minutes. Frost cake.
Editor's Note: Cake is moist and has a firm texture.
