There is no shortage of recipes if you do a search. It is hard to pick one as “best” since they are all different. As I try new recipes I’ll add them.
Smitten Kitchen – These came out pretty good. It was my first time trying one of the recipes from the site. I made some with and some without the chocolate chips. I’d make these again. A little crumbly, but acceptable and that might have been due to the peanut butter I used.
