Peanut Butter Silk Cake

This is a recipe that I found on the back of a Betty Crocker cake mix box and tried that has really been a big hit with the family. I guinea pigged my daughters 4th grade class and it was a huge hit. It has a very subtle flavor and is complimentary to peanut butter icing or regulary buttercream.

I have doubled and tripled with great results.

Do you think this recipe would work for cupcakes? Would they need to be refrigerated because of the filling? I have someone who wants peanut butter cupcakes with pb filling and pb frosting! Do you think this recipe would work?
