can(s) of pie filling or canned fruit in heavy syrup--peaches are perhaps the most common. You want about 28 oz of this more or less but is not exact.
1 box of yellow cake mix
1 can of lemon lime or gingerale soda. Must be sugar/corn syrup sweetened, not diet.
12 inch camping oven, also called a dutch oven--has 3 legs to hold it above the coals and a rimmed lid to hold the coals on top.
Charcoal, about 30 briquets worth
Light the charcoal and let it burn to an even gray. A chimney starter is ideal for this.
Arrange about 9 briquets to fit under the dutch oven, no coals in the center. Put the dutch oven over the coals. Fine tune the placement of the briquets as needed.
Open the cans of pie filling/fruit and pour in the bottom of the dutch oven. Open the cake mix and sprinkle it evenly over the fruit. Open the can of soda and pour evenly over the cake mix.
Put on the lid and arrange 15 coals around the top. Every 15 minutes, rotate the oven 1/4 turn clockwise and the lid 1/4 counter-clockwise. This evens out hotspots that form easily when cooking with charcoal, especially if you're using lump charcoal or coals from a wood fire.
Bake 30-45 minues. Exact timing depends on weather, altitude, cooking in the sun vs the shade and other similar uncontrollable factors. With experence you'll learn to add or subtract coals to better match your cooking environment.
Variations
Spice cake mixes are good also and quite multipurpose. You'll often see chocolate cake mixes used with cherry filling and dr. pepper for the soda with the cherries and chocolate cake.
