Notes
Do not overwork the marshmallows. This is a big one as a lot of people will over stir the marshmallows as they melt, causing them to become hardened as they cool.Also, if you're making this smores dessert with golden grahams on a hot summer day or the house is warm be prepared for the chocolate to make it not want to set. I personally keep my Golden Graham cereal bars stored in the fridge simply because the chocolate can't melt that way. These bars can last up to a week in the fridge before becoming stale. They should still be safe to eat at that point, but the texture is a little different. Some are okay with this and others are not so take note.
