What you will need:
1/4 cup of marshmallows
2 Reese's Peanut Butter Cups (cut into small pieces)
1) Peel a single side of banana down, but do not detach. Use a knife to carve out the exposed portion of the banana (kind of like a boat). Fill the notch with peanut butter cups and marshmallows.
2) Fold peel over the loose ingredients
3) Wrap entire banana in aluminum foil and heat for 5-8 minutes, or until chocolate becomes melty. Don't over-heat though, or else the banana becomes mush. You can make this same recipe in the oven, of course--just set to 350 degrees!
4) The end result. We couldn't get enough! Enjoy!
