This is one of my favorite recipes from TOH. It is easy, it is cheap, and it is DELICIOUS! I think these are my family's favorite cookies. I have even made a batch with pasteurized eggs for making cookie dough ice cream! :) The cook time is for one batch in the oven. The dough freezes well; simply roll into a log and wrap in plastic wrap. Then just slice off cookies and bake (from frozen) according to directions.
