A delectable baked camping treat combining fresh baked brownies and s'mores.
Line a 9 inch cast-iron skillet with tin foil.
Pour the prepared brownie batter into the skillet and cover with a lid. Place it over 13 hot coals, then place 4 more coals on top of the lid. Bake for 20 minutes, or until brownies are done.
Remove the skillet from the heat and remove lid. Place the marshmallows on top of the baked brownie. Break apart the chocolate bar into small pieces and sprinkle on top of the marshmallows.
Place the lid again and place on top of the coals again. Cook until marshmallows are golden brown.
Crush up two graham crackers and sprinkle on top of the brownies.
