Here's a quick and easy dessert that is delicious to eat. The dry ingredients can be mixed together and placed in a ziplock bag ahead of time if you want to fix this one while camping. To make things easier you can even prepare the apples before leaving home and put them in ziplocks in the cooler.
I used the recipe from Texas Treasury of Dutch Oven Cooking .
Grandma 20's Apple Brown Betty
Mix together: 6 cups tart apples, peeled, cored, and sliced. (I used Granny Smiths)
1/2 cup sugar.
Spread evenly over bottom of Dutch Oven.
Top with: 1 cup brown sugar
1 cup oats
3/4 cup flour
1/2 cup softened butter
1 cup pecans (I used halves)
2 tsp cinnamon
1 tsp nutmeg
Bake in 10" or 12" dutch oven using 8 briquets on the bottom and 14 briquets on the top for 20 or 30 minutes.
It's done when apples are tender and topping is brown. Serve with ice cream or whipped cream.
