Peanut Butter Plus Chocolate does not shy away from using up overly ripe bananas in recipes. This averages out to be a weekly thing over here. In my house we have a consistent problem with never eating our bananas. I always purchase a handle when I’m at the store and they sit on my counter all week not being touched. At the end of the week, I’m wracking my brain with ways to use them up. Does this happen to anyone else? Well you can count on my blog to give you endless ideas to use up those nanners.

I have a pretty standard recipe for most of my banana bread endeavors and I will add flavors and such to change them up. But this recipe I decided to start from scratch and I used some ingredients I have never used in my banana bread before. These banana bread bars are extremely dense and moist. Even if you aren’t a big a banana fan, I promise you that these bars will change that. The new ingredients I added changed my banana bread game forever.
