I had this idea two years ago, I call them fire-pit waffle cones: Buy a box of waffle cones and fill one with bananas, marshmallows, little peanut butter cups, rolos, chocolate syrup...whatever you want. Wrap the filled cone with tinfoil and set it in the fire for about 15-20 minutes or long enough to melt whatever you have in there. Open it up and eat it with a spoon or fork by the fire.
The kids like to try different stuff. They've tried Reeses's pieces and skittles, different cereals, like coco pebbles, coco puffs, lucky charms, all kinds of crap. I like to do a smores cone with little marshmallows, chocolate and crushed graham crackers.
We usually set it up like a salad bar in the camper so the kids can do whatever they want. We'll pass around a can of whipped cream to add to the top before eating them. It's kind of fun, and no clean up since they eat the cone too.
