If you have ripe bananas lying around your kitchen, usually your first instinct is to whip them up into an easy banana bread. And while this option is still deliciously good, it can be a bit overdone. For anyone who is after another way to use up bananas, this is a fantastic way to do it. These perfectly dense muffins are so addictive on their own, let alone when you add on the amazing peanut butter icing. These tasty treats are also super easy to bake so they make a great dish to let your grandkids help out with. They’ll have fun cooking with you plus they’ll love the final product!
