Prepare your fire or heat source: hot coals, a gas grill on medium heat, or an oven at 375°F (190°C).

Peel off a small strip of sticker and rinse bananas if needed. Leave the peel intact.

Lay each banana on a sheet of foil.

Using a paring knife, slice the banana lengthwise through the peel (not all the way through the banana) to create a pocket.

Gently pry the banana open and add roughly 2 tablespoons chocolate chips and 2 tablespoons mini marshmallows into each banana. Add a drizzle of peanut butter, a sprinkle of graham cracker crumbs, chopped nuts, or caramel as desired.

Fold the foil around the banana and seal tightly to prevent leaks.

Place wrapped bananas on hot coals or a grill rack. If using an oven, place foil packets on a baking sheet.

Cook for 8–12 minutes, depending on heat and how gooey you want the fillings. Check at 8 minutes; the chocolate should be melted and marshmallows soft.

Use tongs to remove packets and let rest 1–2 minutes (very hot inside).

Carefully open the foil away from your face. Sprinkle with extra graham crumbs or chopped nuts. Drizzle caramel if you like.

Serve in the foil or transfer to a plate for scooping with a spoon.
