Line a Dutch oven with heavy-duty aluminum foil; add pie filling. In a large bowl, combine the cake mix, water and oil. Spread over pie filling.
Cover Dutch oven. When briquettes or wood chips are covered with white ash, place Dutch oven directly on top of 8-10 of them. Using long-handled tongs, place remaining briquettes on pan cover.
Cook for 30-40 minutes or until filling is bubbly and a toothpick inserted in the topping comes out clean. To check for doneness, use the tongs to carefully lift the cover. Serve with ice cream if desired.
