Heat up the hot fudge in a microwave or a pot of boiling water. Pour 1/4 cup of marshmallows into each bag of graham crackers. Next, drizzle in some hot fudge, immediately close each bag, give it a shake and leave closed for a minute so the heat from the fudge can melt the marshmallows. Open and eat with a spoon.
