This year we added one more to the chocolate cake pile: Chocolate Peanut Butter Cake. Well, actually, the technical title of the cake is Sour Cream-Chocolate Cake with Peanut Butter Frosting and Chocolate Peanut Butter Glaze, though it is actually a Sour Cream-Chocolate Cake with Cream Cheese Peanut Butter Frosting and Chocolate Peanut Butter Glaze, but all you really need to know is that if you know a chocolate-and-peanut-butter lover, you must make this cake.
