Banana, Chocolate Chips and Peanut Butter!!!

I can't believe that I have not posted this all-time favorite!

Our banana choco chip cake transformed into a cupcake, with Peanut Butter Frosting!

This is how it looks in a box (which may be mint green or purple in color)...

A look at the cupcake, on the bottom left portion, without frosting...

And, finally, a look at the cross section...

Is it any wonder that this is a best seller???
