Everyone likes to get ahead and get a few batches of cookies into the freezer before the year-end holidays or another big event. Whether the cookies survive freezing depends more on your own freezer than anything else. If the freezer is very clean, not too crowded, and you don’t open it often, your cookies will come through the freezing process relatively unscathed. Crisp cookies may become somewhat limp upon defrosting—if possible, preheat the oven to 300 degrees and reheat them on a cookie sheet for less than 10 minutes, then let them cool before serving.
