Brownie Cookie

Packaged brownie cookies generally last for about 2-3 weeks past their 'sell by' date when stored at room temperature. Once opened, they retain their quality for about 1 week. Homemade brownie cookies, if stored properly, can stay fresh for up to a week. Freezing is also an effective way to extend the shelf-life. Frozen brownie cookies can last up to 3 months.

If the brownie cookies have a stale smell or taste, they're likely past their prime. Mold is a more severe sign of spoilage. If your cookies are moldy, it's best to throw them out. Odd discoloration may also indicate that the cookies have gone bad. If the cookies are too hard or dry, or they have lost their chocolate flavor, they're likely not in the best condition to eat.

• Store the cookies in an airtight container at room temperature. This will help retain their freshness and prevent them from drying out. • Avoid storing the cookies in warm or humid areas, as this can accelerate spoilage. A cool, dry pantry or cupboard is usually ideal. • If you're making homemade brownie cookies, allow them to cool completely before storing them. This will help prevent condensation, which could make the cookies soggy. • Consider freezing cookies that you won't be consuming immediately. Make sure to wrap them securely in plastic wrap and place them in a freezer-safe bag or container. • When you're ready to eat the frozen cookies, you can defrost them at room temperature for about an hour. Alternatively, you can warm them in the oven at a low temperature to restore their fresh-baked taste and texture.
