Remember when I won all of those goodies and I pontificated about using Peanut Butter & Co's White Chocolate Wonderful for cupcake icing? Behold banana mini-cupcakes with white chocolate peanut butter frosting*! Patience is not one of my virtues.
For the cake I used VM's go-to banana bread recipe (an oldie but goodie).
It took a lot of restraint not to add the requisite chocolate chips, but I was baking for a crowd of peanut butter/chocolate haters (Yes, really; they exist. It comes in handy when you don't want to share your peanut butter cups).
I hate to admit it, but the chocolate chips would have been out of place. The combination of the light, banana cake and the rich frosting was ideal; these definitely didn't need another element.
The rest of the jar is now hiding in the back of my pantry with the like-sized and equally dangerous Biscoff spread.
Epiphany: this combo would make a great cakewich too!
*If you're pressed for time, I'd also recommend preparing this as an iced loaf.
