I freeze my iced cookies up to a month and they're as fresh as the day I baked them. I like to store them in an airtight container. Strangely, if they're individually bagged, they go stale faster.
I'm doing Halloween cookies, so I won't be freezing them. Just wondering when I could get started on them and not have them go stale. Would Thurs. or Fri. be too soon? thanks so much.
