Most cookie doughs freeze extremely well and can be kept frozen for up to 4 or 6 weeks. The most important thing to keep in mind is that the dough will absorb any odd odors present in your freezer if it's not properly wrapped and sealed. To prevent this smell-sponge effect-as well as freezer burn-wrap the dough securely twice. It's also a very good idea to write the type of cookie dough and the date it was frozen on the outside of the package. When you are ready to bake simply let the dough defrost in the refrigerator. This will take several hours, so plan ahead. The cookie doughs that freeze best are shortbreads, chocolate chip, peanut butter, refrigerator, sugar, and brownies, just to name a few. The types of cookie doughs that do not freeze well are cake-like cookies and cookies that have a very liquidy batter. Jay
Here is one thing to add to this great idea. I don't like making a whole batch of cookies because I am one of those people who thing fresh is best. So I make a whole batch and on a cookie sheet I spoon 2-3 dozen cookies (whatever will fit as long as they don't touch). I then put the cookie sheet in the freezer until they are firm, then put them in a freezer bag and whallah! You can make whatever amount you want. I just add a few minutes to cooking time. I have tried this method with about 4 different recipes and have great results!
