This is the best peanut butter cake and frosting I have ever tasted. I made mine in a 13x9x2 pan, and it turned out great. The icing was to die for! My husband does not like peanut butter that much, and he could not stop eating this cake. Definite 5 stars! By the way, my oven runs hot, so I only baked for 20 minutes.
