S'Mores Galore

Anyone who really knows me knows my weekness is S'mores! They are a must at a campfire but also all summer long! I love this pampered chef recipe because you dont need a campfire for these bad boys! They are so fun to bring to any summer outings or parties!
PS: this recipe is totally different from my other 2 smore recipes posted previously, just fyi.
