Expiration & Storage Tips
When does sandwich cookie expire?
If unopened, a store-bought sandwich cookie's shelf life typically aligns with the printed date on the package - usually around 6-9 months. Once the package is opened, they tend to stay fresh for about 1-2 weeks, as long as they're stored in a tightly sealed container to avoid exposure to air. When it comes to homemade sandwich cookies, enjoy them within a week. If you freeze these cookies, they can last about 3-4 months.
How do you tell if sandwich cookie is bad?
Telling if a sandwich cookie has gone bad is generally done by examining its texture and taste. The cookies will start to lose their crunch and become soft when stale. If you bite into one and it tastes off or has lost its distinct flavor, that's another hint it may have expired. Lastly, any signs of discoloration or mold signify that the cookie has gone bad and should be discarded immediately.
Tips for storing sandwich cookie to extend shelf life
• Always store sandwich cookies in a cool, dry area out of direct sunlight. Warm or humid conditions can speed up the degradation process.
• For opened packages, keep the cookies in an airtight container or reseal the original packaging to keep the cookies fresh.
• For long-term storage, consider freezing the cookies. Make sure they are well-wrapped in a freezer-safe bag or container to prevent freezer burn.
• If you've baked homemade sandwich cookies, let them completely cool before storing them away. This prevents moisture build-up, which can cause them to go stale faster.
