Expiration & Storage Tips
When does Peanut Butter Cookies expire?
Unopened store-bought peanut butter cookies can last up to two weeks past the best by date on the package, as long as they have been stored in a cool and dry environment. After being opened, the cookies will maintain freshness for about a week, if stored in an airtight container. Homemade peanut butter cookies will stay fresh for 2-3 days at room temperature. If you freeze your cookies (which is quite common), they can last for up to 3 months.
How do you tell if Peanut Butter Cookies is bad?
Start by checking the appearance of your peanut butter cookies. If they appear dry, hard, or have discolored spots on them, they have possibly gone bad. A stale smell or taste is also a clear indication of spoiled cookies. Finally, any signs of mold mean the cookies are no longer safe to eat.
Tips for storing Peanut Butter Cookies to extend shelf life
• Store your cookies in an airtight container to prevent them from absorbing other food odors and to maintain their freshness. Make sure to seal the container well each time you take a cookie.
• Keep your cookies in a cool, dry place to avoid moisture build-up.
• If you have a large batch of cookies, consider freezing some. Place them in a freezer-safe bag or container. Just remember, you have to thaw them at room temperature before eating.
• A piece of white bread in the cookie jar can help keep cookies fresh longer by taking in excess moisture.
