Eldest made some for a class project and got an A+
We also have made them with chocolate chips and mint chocolate chips in place of the peanut butter ones. They were all good!
This is a fun cookie to make too! Who doesn't want to stick their thumb in a cookie?

Great. Now I want to bake them again.
