Substitute a peanut butter cup for the chocolate.

I had the idea to change the classic s'more equation weeks ago, but didn't have the opportunity to prove my new formula until this past weekend. The experiment was a complete success. S'mores will never be the same again. I thought I had made an amazing, possibly Nobel Prize-worthy discovery, but it looks like I was beaten to the punch. When I googled it I found the above image at Wikipedia. Ah well, everything's been done before. I won't let it stop me from performing further experiments with caramel, cinnamon grahams, and pretzel crackers.
