Cookie Preservation Although our cookies do not contain any preservatives, they do have a guaranteed 7-10 shelf life from the time you receive them. If you prefer to nibble rather than munch … and need to preserve their freshness a little longer, place your cookies in a sealed container and freeze (up to three months) until your next cookie craving. When ready to eat, remove from freezer, and let come to room temperature in the sealed container (this prevents the cookie from sweating due to the change in temperature). ENJOY!
