Spray the interior of the camp cooker with non stick spray.

Carefully open the Phillsbury can and place one cinnamon bun into the pie iron.

Close and latch the iron.

Cook the cinnamon bun over the campfire for about 15 minutes.  A small campfire at a low temperature works best so that the dough has time to cook all the way through. 

Flip and unlatch the camp cooker several times to check for doneness.

Remove the bun from the cooker and top with frosting.
