Pillsbury does some damn good cookie mixes.

Tried their snickerdoodle mix.  The only complaint I had (that there wasn't enough cinnamon sugar for all three dozen cookies the mix claimed to make) was easily remedied.

The cookies are damn good.  There's already been about a dozen disappear between Odysseus, the pixie, and me (the imp tried them, but didn't like them).

Make sure you use real butter when you make them.  Margarine and shortening just don't have the right flavor.
