Preheat the Dutch oven or camp oven to 350 degrees F (175 degrees C).
Topping
In a bowl rub together the flour and butter until it has a texture similar to breadcrumbs.
Stir in brown sugar, oats, almonds, coconut, and cinnamon.
Apple Crisp
Peel and core the apples, then thinly slice.
Lay the apple slices evenly in the jars. Alternatively: You may use a single Dutch oven or casserole dish.
Sprinkle the topping mixture evenly over the apples. Note: When the apple crisp cooks it will first expand slightly so be aware of overflow, then on cooling the apples soften and shrink, allowing the topping to drop down. Take this into account when filling so it doesn't overflow.
Bake the crisp in the preheated Dutch oven until the apples are tender and the top is golden. This takes about 30 minutes. Tip: If using a single large dish such as a Dutch oven or casserole dish, it will take about 10 minutes longer to cook.
