Whitney wrote in recently to ask about freezing cookies:
Do any of your cookies freeze well? Can you freeze baked cookies as well as the cookie dough?
Hi, Whitney. Thanks for writing in. The baked cookies hold up really well in the freezer. I know from experience.
I've frozen cookies plenty of times, and they stay tasty for about 3 weeks. The cookies I froze were supposed to be for distribution later on to far-away family and friends, but--truth be told--they didn't always last long enough to make it to their intended destinations. I'll eat cookies hot, cooled, frozen, or thawed. It's that frozen part that often sabotages my good cookie-spreading intentions.
Frozen cookie dough holds up well, but I have noticed that cookies made with frozen dough bake up a little rounder than cookies made with fresh dough. The frozen guys don't spread out or flatten much--something to do with the leavening, I think. They're not as pretty as the ones made with fresh dough, but they taste just as good. But, of course, the danger of having frozen cookie dough on hand is that you've got frozen cookie dough on hand. Be prepared to snack on dough nubbins snapped from the mama log until you've got only enough dough left to bake off a few misshapen cookies.
