I only wish I would have thought of this method sooner! It's perfect for keeping the cookie jar filled with freshly-baked cookies, without forcing you to eat a dozen every day. :) (Not that I have experience with this!)
How to Freeze Cookie Dough

air tight freezer containers
Once your cookie dough is completed, scoop dough onto a cookie sheet as you usually would if you were going to bake them. Roll each scoop in the palms of your hands to create a perfectly round ball. If the cookie is to be rolled in sugar or cinnamon-sugar, complete that step at this point. Place the round dough balls on a cookie sheet 1/2 to 1 inch apart. Place the cookie sheet(s) in the freezer, under covered for 1 to 2 hours, or until balls are thoroughly frozen. Transfer dough balls to an airtight, freezer proof container and store up to 3 months.
When it's time to bake preheat the oven to the temperature the recipe indicates. Arrange desired number of frozen dough balls on a cookie sheet 1-2 inches apart. Bake for the prescribed time, adding 1-3 minutes to the end of the baking time, if necessary. Cool as usual.
