This isn't for the faint of heart, but take a deep breath and begin!! I acquired this recipe out of a magizine given out by my local Safeway store. Prep. time is about two and a quarter hours. Makes eighteen to twenty slices. Will keep in the fridge for up to two days. It was a resounding success at our family Christmas dinner. When you spread the caramel-hazlenut butter cream it doesn't seem like enough but I covered the cake as best as I could and it was fine, but when you separate the mixtures into the bowls you could probably add a little more than the 2/3 cup the recipe calls for if you like.
