First things first, you’ll need either a campfire or a heated grill. Before you start filling your banana, either get a fire going or heat up the grill.
Next, cut a slit down the length of the banana on top, making sure you don't poke through the back peel on the banana. Note: You may want to wash your bananas before you ever start.
Next, layer chocolate chips, mini marshmallows, and graham crackers in the slit you cut in the banana. Squish and fill as full as possible.
Completely wrap your banana boats s'mores in aluminum foil. Make sure it’s completely covered.
Add to a warm grill, or place in campfire coals.
Allow the s’mores to cook for about 5 to 10 minutes.
Using a pair of tongs, remove your banana s’mores from the fire or grill, and carefully unwrap the foil; be careful, it’s hot! Watch the marshmallow especially as you unwrap, so you don’t get burnt.
The banana will have turned mostly brown/black. You can let it cool for a few minutes, then dig in and enjoy!
Notes
Cooking Tip: Amounts of chocolate chips, marshmallows, and graham crackers may vary, depending on the size of the bananas.
