This idea was the next natural step I think, brought to me via Culinary in the Desert. The possibilities are endless, you can stick pretty much whatever you want in a cookie - and even if you repeated the surprise inside the cookie, you can put it in so many different kinds of cookies!! The original recipe has peanut butter in the dough as well as the filling - but no chocolate chips. So I didn't use any peanut butter in the actual cookie, but I did load it up with chocolate chips. Of course. I also replaced the icing sugar in the filling with brown sugar because as much as I love icing sugar, I just think brown sugar goes way better with peanut butter.
