This is usually made in a dutch oven over a campfire.  (You can get foil liners now – no cleanup!).  Most people don’t cook that way.  Here is the oven method.  You can do the same thing with applesauce and spice cake.  It’s called Brown Bears in the Apple Orchard by the Girl Scouts.

Ingredients:

• 2 (21 ounce) cans pie filling (half a #10 can) peach, apple or cherry work best.
• 1 c butter, melted (if camping just chunk it)
• 18 ounces yellow cake mix or 18 ounces white cake mix

Directions:

1. Spread 2 cans of pie filling in bottom of 9 x 13 pan.
2. Sprinkle with cake mix.
3. Pour melted margarine over the cake mix.
4. Bake at 350° for 50 minutes.
5. Cool slightly – hot sugar  will burn your mouth!
6. Top with  whipping cream when cooled.

Serves:  16 – 20 unless they are Boy Scouts – then about 6.
