Peanut Butter Sheet Cake

Cassie *


This cake should take care of any cravings any die hard peanut butter fan would have. The delicious peanut butter frosting is so smooth and creamy. It would also be great on peanut butter cookies.

The cake is great alone, or as I did, add some peanuts and chocolate chips. Can't go wrong with PB and Chocolate.
