Place graham crackers on cookie sheet.

Put 1 square of chocolate on each cracker.

Place a marshmallow on each piece of chocolate.

Place cookie sheet in a 350° oven for 4 to 6 minutes, just long enough to melt marshmallow and soften the chocolate.

Remove from oven and put another graham cracker on top to make a sandwich, or leave as an "open-face" sandwich if you're like me!
