I made most of our Christmas cookies this year at the last minute, but they all turned out. These were the easiest, but everybody seemed to like them: the quick-mix sugar cookies linked here, with a little canned frosting and coloured sprinkles in the middle. I didn't press the cookies down as directed with a sugared glass, because I knew I was going to be adding frosting; I just flattened them with my fingers.
The frosting was squished from a Ziploc bag with the corner cut out, so that I could frost them in a little spiral shape (I don't think you can see that so well in the photo).
(That one on the edge is a mutant.)
