Is it ok to eat out of date smarties cookies?

Eating out-of-date Smarties cookies is generally not recommended, as they may have lost freshness and flavor. If the cookies are only slightly past their expiration date and have been stored properly, they might still be safe to eat, but always check for any signs of spoilage, such as an off smell or unusual texture. It's best to use your judgment and prioritize food safety. If in doubt, it’s better to err on the side of caution and discard them.
