I have been getting into the Dutch Oven thing for over a year now. Been doing mostly the fruit cobler type deserts. Our family really likes this one...
2 cans of Apple fruit pie filling
1 yellow cake box cake mix (One that uses water, eggs and Butter)
1 can of Sprite (or Siera Mist, etc)
Cinnimum and brown sugar mixture
Use the sprite in place of the water to mix up the cake mix.
Place foil in the Dutch Oven, spray with Pam, dump in the pie filling, then pour the batter on top and sprinkle with the cinnimum and brown sugar mixture.
Bake for about 50 min to 1 hr with 10 - 12 coals on bottom and 15 coals on top.
Check only once about 40 minutes into cooking to make sure it is cooking evenly. Use the tooth pick method to make sure it is cooked all the way through.
P.S. We use the cinnimum and Brown Sugar mixture for doing baked apples, or French Toast. We keep a container of it on hand every time we camp.
