3 cans peaches
1 can crushed pineapple
1 butter recipe cake mix
1/2 - 1 cube butter
Drain the peach juice into a bowl and add all 3 cans of peaches into dutch oven. You don't have to be real picky about completely draining it. I drain off most of the juice with the lid and then dump them. Add the crushed pineapple without draining it. Mix with a spoon and spread evenly over the bottom.
Sprinkle cake mix over the fruit evenly. Take the cube of butter and cut little slices off of it and spread over cake mix. You can use as little as 1/2 of the cube to as much as the whole thing depending on your tastes. Then drizzle the peach juice over the whole thing as evenly as possible. Place the lid on and then set in the coals and add a few to the top of the dutch oven to cook the top.
I would check it after about 15 minutes to see how quickly your coals are cooking it. If its burning, they are too hot. If it looks the same you might want to add more.
