In 12 inch foil lined Dutch Oven, combine fruit and tapioca. Sprinkle cake mix evenly over top of fruit. Sprinkle brown sugar over cake mix. Dab butter all over top of brown sugar.
Place lid on oven. Bake 45 minutes to 1 hour. Use 6 to 8 coals on the bottom and 14 to 16 on the top. Cake is done when top is brown and cake has absorbed juices and is no longer dry.
