I’d choose this over s’mores any day!
“Chocolate Cake Baked in an Orange
Cut the tops off about 10 oranges and scoop out the pulp. Fill the oranges three-quarters of the way with chocolate cake batter (cake mix works fine), then put the orange tops back on and wrap each orange in aluminum foil. Place directly onto the smoldering coals of the campfire, avoiding any intense flames, and cook for about 30 minutes, turning once or twice.”
