I make this cake often, just made for a graduation party, but I sub the frosting. Try this... Use 2 oz. chocolate chips in the cake. Then for the frosting, boil 2C heavy cream, remove from heat, stir in 1/2C powdered sugar, 1/8t salt, and 1 lb chopped dark chocolate. Whisk til smooth, and refrigerate for about 2hrs, stirring occaisionally, it will thicken up when it's cold. Makes enough for this cake, about 4C. Make the frosting first, so it starts to cool while you make the cake. YUMMY!!
