Start by washing your ripe but firm bananas thoroughly. Using a sharp knife, carefully slice each banana lengthwise, creating a pocket in the middle without cutting all the way through.

Gently open the pocket of each banana and stuff it generously with chocolate chunks or chips, followed by mini marshmallows. Consider adding some chopped nuts or fresh berries.

Take heavy-duty aluminum foil and cut pieces large enough to wrap each banana completely. Tightly wrap each filled banana in foil.

Position your foil-wrapped banana boats near a bed of hot embers—not directly over an open flame—to achieve even cooking. Cook for about 15-20 minutes.

Once cooked, carefully unwrap the foil and serve the banana boats directly on a plate or let everyone dig in straight from the foil.
