You can very versatile with these cookies, I made these with smooth peanut butter and added a cup of chopped pecans. Some of you seem to be having trouble with these cookies. You have to bring them to a hard rolling boil before dropping on wax paper. Once you drop them on the paper, move to a cool place to harden. You could put in the refrigerator or even the freezer for a while. Once they are hard keep in an airtight container in a cool place. I have kept them up to two weeks.
