Chocolate, Banana, Peanut Butter Cookie Dough Cupcakes

That’s a pretty long title but it could have been longer. The full description is chocolate, banana and peanut butter cupcakes stuffed with peanut butter cookie dough and topped with peanut butter cookie dough buttercream frosting. That might sound over the top but they were some of the best cupcakes I’ve ever eaten. It’s been a long time since I shared any baking with you and almost as long since I actually did any, so I wanted to return with something I hadn’t made before. I noticed some overripe bananas last week while I was making a peanut butter sandwich and thought that they’d make a pretty good pairing. Chocolate was the obvious common denominator but I still think these would be very tasty without the addition of the cocoa powder.

I thought the buttercream might be a bit heavy once the cookie dough was mixed it but it was so light with a subtle taste of peanut butter. They don’t take too long to make either – you can prepare the cookie dough and buttercream while the cupcakes are in the oven. The light, moist cupcake and fluffy buttercream are balanced perfectly by the nugget of cookie dough that is hiding in the middle. They were absolutely delicious and the flavour combination was even better than I’d hoped. I’ll definitely be making thse again in the future.
