We had a swamp party for Nathaniel's birthday. The recipes for the cake and the icing were from The Cake Bible by Rose Levy Beranbaum. The White Chocolate Whisper Cake did not turn out as well as it could. I will say that it was me and not the recipe. I had to make a couple of substitutions and they, I believe affected the outcome of the cake. I also used the Neoclassic Lemon Buttercream and the Winter Blueberry Topping. They both were spot on perfect!!
