Campfire cones are great single serving snacks/desserts that can be made ahead and cooked when you want them.
Step 1: BoM
Ice cream cones
Step 2: Stuff
Stuff your cones however you see fit. I wanted a s'mores kind of cone, so I put in M&Ms, marshmallows, Nutella, almonds, and then more marshmallows (to keep the Nutella from leaking out).
Step 3: Wrap
Wrap each cone in a small piece of tin foil. Start by folding at the bottom and then wrapping the sides. Close the top. I made a little hook so I could put the tin foil on to a skewer later for easier cooking.
Step 4: Cook
Heat up your cones for 3-5 minutes over your fire. If you have marshmallows on top and want them a little crispy, you'll need to expose them to some flame after the cone is cooked. This method melts, but doesn't char the inside of your cones.
Step 5: Enjoy!
Carefully remove the cones from the heat and even more carefully, unwrap them and enjoy!
