When I need to make cookies, like around the holidays, I set aside an entire day just to make cookies. I use the cake mix cookie recipe usually but sometimes I make others too. I put the dough into freezer bags, flatten it to about 1" and freeze it. Then when I bake I can take out several bags of different kinds of cookies, cut off what I need, reseal the rest, and with one large cookie sheet usually bake enough for unexpected company or cookie starved family. I can have a nice assortment of cookies in a matter of minutes and only have one cookie sheet and one knife to clean.
