DEE-LICIOUS GOURMET XLARGE COOKIE IN A PAN Dee's Large cookies are individually wrapped and sealed to preserve out-of-the-oven freshness. To save our cookies for later, here are some tips: Do not refrigerate any of our sweets, as that will dry them out. Instead, store them in their original sealed packaging or an airtight container at room temperature for up to two weeks. Dee's baked products have a shelf life of 10 days, we recommend enjoying your treat as soon as it is received for optimal taste and freshness.
