I made 3 batches of these for a New Year's Eve party this year, and they were a huge hit.
I had no trouble finding grahams without honey at Central Market. They said Honey Grahams, but looking at the label, they had no honey in them. I couldn't find maple sugar, so I used turbinado. This wasn't the best option because it didn't dissolve in a timely fashion. I also had to adjust the graham cracker crumbs up because the Central Market all natural peanut butter that I used for the first 2 batches was a bit thinner than the other brand. I considered just tripling the recipe instead of doing it 3 times, but it really was easy allowed me to adjust along the way.
The serving is huge. I think next time I will either put 1tb of peanut mix in the cups and spread the recipe out over 24 cups (this would require doubling the chocolate) or getting mini cups and doing that.
