Serve this versatile cake plain, with a dusting of sifted powder sugar, with fresh berries and a dollop of lightly sweetened whipped cream, alongside a scoop of ice cream and a drizzle of caramel sauce, completely covered with a smooth ganache, or swirled with a luscious cream cheese frosting. Bake in two 8" or 9" round or square pans, or in one 9" X 13" pan.
