Take a banana with its peel still on and cut it down the middle (carefully along the concave side) making sure to not cut through to the other side but go half into the banana so you can open it.
2 Bananas
Pull the peel and banana slightly apart and stuff the chocolate and mini marshmallows (or other fillings, see note) into the center of the banana.
1/4 Cup Milk Chocolate Chips , 16 Mini Marshmallows
Wrap the banana back in its peel and then in foil. Place on a campfire or grill until fillings have melted and banana has warmed through, about 10 minutes.
Unwrap banana and Enjoy!
Notes
Additional toppings could include: graham crackers, berries and cream, Biscoff, Reese's, chocolate sauce, caramel, white chocolate chips, sliced strawberries, whipped cream, etc.
