At room temperature, most cookies will last up to a week. If the cookie contains any type of dairy, it will need to be refrigerated and eaten within seven days. You can freeze all kinds of cookies for up to six months.
1. Room Temperature – Up to a Week
Most cookies will be able to sit on your kitchen countertop for up to a week as long as they’re stored correctly. This is the ideal spot for cookies. They will be able to retain their shape and texture.
2. Refrigerator – Up to Seven Days
Not all cookies can be left at room temperature.
If your cookie contains any dairy product, such as custard or whipped cream, you must place it in the refrigerator ASAP.
Like other types of dairy products, dairy-filled or dairy-topped cookies can’t sit out at room temperature for longer than two hours (or one hour if the temperatures exceed 90F).
Get them into the fridge immediately. They will be safe to consume for up to seven days.
3. Freezer – Up to Six Months
If you don’t plan to eat your cookies within a week, you’ll need to place them in your freezer.
When frozen, all types of cookies will remain fresh and yummy for six months.
Note: Cookies will still be safe to consume after the seven-day mark. Again, it comes down to quality. After six months, the cookie’s quality will begin to deteriorate. That’s why it is better to eat frozen goodies sooner rather than later.
