One of my favorite all time campfire snacks is a baked apple made right in the fire. It's easy to make, too!
You take an apple, any kind that you like, and core it about half way down. Make sure you leave some of the bottom still attached.
Take about a tablespoon of butter and fill the cored part. Sprinkle with some cinnamon and sugar and raisins if you like them.
Wrap the whole apple in foil and place in the fire for about 5 minutes. Use a mitt to remove and let it cool for short amount of time.
When you unwrap the apple, it will taste just like apple pie!
