I made this in a pinch with ingredients I had sitting in the pantry. The cake is pretty darn tasty even without the frosting. My peanut butter-loving family says this is now their favorite dessert. And what doesn't go with peanut butter? You can drizzle chocolate on the frosting or place sliced bananas between a two layered cake. Your favorite jam would go great dolloped on top of cupcakes! Oh, the possibilities are endless. I hope you enjoy it.

This cake is a must-make for any peanut butter lover. And it's so good it may convert non-peanut butter fans. You taste peanut butter in every layer of the cake and icing. A great moist and delicious cake!
