Stick a marshmallow on the skewer and toast to desired done-ness.
Place a peanut butter cup on a graham cracker square. Place the perfectly roasted marshmallow on top of the peanut butter cup. Top with another graham cracker square and sandwich together.
Let sit for a few minutes, to allow the chocolate to melt just a bit. Now devour!
Cook's Note: To prepare indoors, place a graham cracker square on microwave safe plate. Top with a peanut butter cup and one marshmallow. Microwave for 10 seconds. Remove from the microwave and top with another graham cracker square and sandwich together.
