I have also frozen the cookies for weeks, if not months,-- even those with fondant and they were just fine. I have frozen the dough for a while too-- not sure how long-- and then baked them. THey don't seem to be a problem.
THANK YOU, THANK YOU, THANK YOU! I will be baking the cookies this week, and freezing them for Halloween. Is there anything special that I need to do as far as packaging or thawing?
