Heat briquettes in chimney for 15-30 minutes until briquettes turn white. Directions here.
Line the dutch oven with heavy duty foil*. Spray foil lightly with cooking spray.
Spoon cherry pie filling into foil lined pan. Sprinkle dry cake mix evenly on top of fruit.
Pour Black Cherry Soda over dry cake mix. Mix gently with fork so the soda doesn't mix too deep into the cherry layer. Don't worry about mixing too much, the moisture will even out during baking.
Place the dutch oven lid on.
Place 7-10 coals below the oven, and 16 coals on top of the oven in a circular fashion.
Bake 25-35 minutes for a 14 inch oven and 30-40 for a 12 inch oven.
Check after about 15 minutes. When cake is done, remove from heat and sprinkle with chocolate chips. Place lid back on and allow chocolate to melt. Serve warmwith cream or ice cream.
Notes
-Dutch Oven purists will probably frown upon the use of foil to line the pan. I say easier is better while camping. You may make this dessert without lining the pan, but be prepared to clean up a sticky mess off the bottom of the pan :)-I suggest preparing this dish before dinner. After the cobbler is done cooking, remove from heat. It will keep warm for at least a couple of hours with the lid on.-When we first started Dutch oven cooking, we (I use the term "we" loosely) thought if 10 coals on the bottom were good, 20 were better. Not so. If the recipe calls for 10 on the bottom and 16 on the top, follow the recipe suggestion. Or you'll have blackened cobbler.-When baking in a Dutch oven, more of the coals should be on top (or on the lid) of the oven to prevent burning the bottom of the dish.-Briquettes vs other brands- Kash only likes to use Kingsford. I agree. We have experimented with other brands, Kingsford is best.
