Oh. My. God. *moan* These are SO decadent, like richer, cookie-ish, layered s'mores. I love everything Hershey's, and this is no exception. This recipe is courtesy of the Hershey's Kitchens site, so you know it's good! This is my favorite diet cheat...beware, though. Once you start eating these, you will NOT be able to stop. ENJOY!

wow. these. are. AMAZING!!! I made them last night for a 4th of July BBQ. I tried one...just to be sure they were servable ;) and they are soooo goood!!! the chocolate doesn't quite solidify completely, and the marshmallows are still a little gooey -- even when completely cooled. Tastes JUST like a s'mores only less messy!! They were super easy to make, too! I doubled the recipe, 'cause 16 just seemed like too few, and they turned out great! Will make again!

This was finger smacking good! One egg was omitted from the ingredient list but is still mentioned in the instructions. Yum
