Creating the Campfire Apple Crisp in Foil is an enjoyable and straightforward process. Follow these steps:

1. Prepare the Foil: Tear off a piece of heavy-duty aluminum foil about 12-15 inches long.
2. Prepare Apple Mixture: In a bowl, toss the sliced apples with one tablespoon of brown sugar and a sprinkle of cinnamon.
3. Prepare Crisp Topping: In another bowl, combine oats, remaining brown sugar, flour, cinnamon, melted butter, and a pinch of salt. Mix well until crumbly.
4. Assemble the Foil Packets: Place half of the apple mixture in the center of the foil. Top with half of the crisp topping. Repeat the process, creating a second layer.
5. Seal the Foil Packs: Fold the foil over the apple and topping mixture, sealing all the edges well to prevent leakage.
6. Cook Over Campfire: Place the foil packet over hot coals, not direct flames, for about 20-25 minutes. Flip halfway through for even cooking.
7. Checking for Doneness: Carefully open the packet. The apples should be soft and bubbling, and the topping should be golden and crispy.
8. Serve: Remove from the coals using tongs. Let it cool slightly before opening the packet to prevent burning.
9. Optional Serving: Serve warm with a scoop of vanilla ice cream on top for a delectable treat.

Following these simple steps ensures a delightful dessert that everyone will love!
