Depends on what type of cranberry cookie it is.

If the cookies are handmade by yourself, they are usually kept in an airtight, light-proof, cool place at room temperature for about a month in winter and half a month in summer.

If the cookies are like other cookies that you buy on your own outside of the home, for example, Zhan Cui's office snacks, snacks, and assorted real fruit cranberry type cookies, stored in a cool place in a dry place, away from direct sunlight and high temperatures, it can have a shelf life of up to 360?days.

I hope this answer can bring you some help and be adopted.
