This was an awesome recipe! First of all, I love cake mix recipes because they lend themselves to experimentation so well. I had two whole batches of bananas going bad at one time, so made two versions. The one printed here was sooo good! I recommend microwaving the peanut butter and the frosting together in a bowl and then stirring. Also, it goes on the cake more easily if the cake itself is still warm. The second version I tried was with a spice cake mix--all else the same, although I think a butterscotch pudding would be interesting, too. I used a pecan coconut frostingl (the popular one for German chocolate cakes), and wow!! Next time (probably Thanksgiving) I'll do the spice version with caramel frosting and see which one I like better. Happy baking! Kari

Peanut butter and bananas, one of my favorite flavor combinations. The only thing missing to make this cake heavenly is chocolate, and I managed to remedy to situation for me by using a dark chocolate cake mix instead of a yellow cake mix. Still used the vanilla pudding, and this came out great! You do need to nuke the frosting to make it a little runny, the top of the cake is a bit moist and I don't think frosting would spread very well, especially when thickend by peanut butter. Shae, thanks, this one is going to become a family favorite!

I love this recipe... It is a great way to use up the lonely bananas. I use a banana cake mix, a banana pudding and add mini-chocolate chips!!! Sometimes I even add a little bit of mexican vanilla! Yum! Thanks for posting!
