Using a paring knife, core the apple from the top, leaving a bit of apple at the bottom. Fill center with a bit of butter and your favorite caramels. Place apple in center on (I perfer 2 squares) foil square. Fold edges up around apple, twisting together at top.
Place wrapped apple on coals of campfire (10 - 20 minutes) until apple is soft when poked with fork. Transfer apple to plate or eat right out of foil. Yummy!
