The peanut butter recipe I used was the classic one from the Better Homes & Gardens cookbook. You can google it and there it is. I never use crunchy PB and never add nuts, either - just good ol' smooth peanut butter deliciocity.
I also wanted to bake something chocolate, so I searched around a little. This recipe started out as one in a cookbook I have that's devoted to just cookies, and I messed around with it just a bit to satisfy myself. When I test a new recipe, I always watch to see reactions from other people, especially when they don't know that I was the one who made it, so I can get an honest idea of whether it's a recipe worth keeping or not. At the party, I overheard several people asking "who made these?" and another couple of times, I heard "you have got to try these" so I think I'm safe in assuming that they were a hit and this one's a keeper. In my book, it's become my favorite cookie ~ at least for now!
If you are a chocoholic, make this. It's soooooo good.
