This cake is from the famous Rose's Resaturant and Bakery in Portland Or. the woman who opened Rose's came to America from Russia as a young woman and used to bake in her very own kitchen!!! then transport the baked goods to her small Bakery every morning! she eventually expanded to a few resturants/Bakery. Sadly I think she passed, and the Restaurants eventually closed, back in the 80's she made 2 cookbooks..this is the description of the cake: FOLLOW THESE INSTRUCTIONS EXACTLY. THE RESULT WILL DELIGHT YOU. THE RECIPE IS WORTH THE PRICE OF THIS BOOK!!! also there is a chocolate version with a marshmallow icing that I will also post seperately that we serve @ every birthday.
