A great way to change up the best treat ever! I like to substitute Reese's Peanut butter cups and the mini Milky Ways (cut in half lengthwise) for the Hershey's. I have to admit I prefer the Milky Way over Hershey's.
This was a scrumptous gooey treat. Although I wasn't sure how I felt about the peanut butter at first, once I actually tried it I think it went quite well with the other ingredients. Like you, I might actually use more peanut butter next time. I also made one minor adjustment to the recipe. Instead of simply putting the hersey bar on the graham cracker, I placed a piece on the graham cracker and then warmed the chocolate and graham cracker up in the microwave for 30 seconds. Made for PAC Fall 2009.
I love how you think! This sounds divine!
