White chocolate peanut butter banana cake may be a long name to say, but these delicate beauties are so easy to make that they are perfect for any class party or large get together. I’m always looking for a new recipe that I can take to a party, or group gathering that will be easy to prepare and serve a ton of people without extra work on my part.
Banana cake kind of went crazy for a little bit on Pinterest. Do you remember that? Everyone seemed obsessed with that light and moist little cake with a cream cheese frosting. And then as quick as it came other recipes started getting all the hype and slowly banana cake faded off into the background. It is quite sad because sometimes I think that those old, classic, family recipes are the real favorites and we get all sucked into the newest poke cake or stuffed cookie that we forget that we could be playing with some of our old time favorite crowd pleasers
Well, this blog is all about “reinventing family dinner” so why not reinvent our favorite banana cake? This is still the same, moist, tender crumbed cake but it has a little hint of a white chocolate peanut butter in it. It’s so subtle you’d almost miss it, but your guests will definitely be wondering what you did to make your cake extra special.

How Do You Keep Bananas From Ripening Too Fast?

Can this be doubled and put in a 12×18 cookie sheet or is it too deep?
oh! It should read 12×18. Not sure what happened.
