The recipe can be frozen, triple-wrapped, for up to three months. Adding 1/2 to 1 cup of roughly chopped toasted walnuts or pecans can also add punch and a change of pace to the recipe. Serving suggestions: The cake may be iced with chocolate butter frosting or alternatively simply sift confectioners' sugar 'snow' onto the cake top after cooling or place a slice of cake into a pool of commercial raspberry puree then for decoration add whole fresh raspberries. Top with a dollop of whipped heavy cream.
