DIRECTIONS
Coat two 9-in. round baking pans with cooking spray and line with waxed paper. Coat the paper with cooking spray and dust with flour; set aside. In a large mixing bowl, beat butter and sugar until crumbly. Beat in the egg, egg whites, melted chips, applesauce and vanilla. Combine the flour, baking soda, baking powder and salt; add to peanut butter mixture alternately with buttermilk.
Pour into prepared pans. Bake at 350° for 20-25 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
For frosting, in a small mixing bowl, beat cream cheese, melted chips, vanilla and salt until light and fluffy. Beat in confectioners' sugar until smooth. Spread between layers and over top and sides of cake. Garnish with peanuts if desired. Store in the refrigerator. Yield: 12 servings.
