Here are the things you'll need.
Lay out your graham crackers on a baking sheet. Pre-heat your oven to 350 degrees.
Place one mashmallow on each graham cracker and put into oven for approx 3-5 minutes
(caution, watch them - these burn very quickly).
Pull them out and immediately place another graham cracker on top.
Heat up some chocolate on a double broiler and dip the graham crackers sandwiches.
Lay them out to cool and sprinkle some graham cracker dust on them for decoration.
That's it. I put them on this great wooden board. They were gone in seconds.
