What to do with stale chocolate cookies?

Answer 1

Chances are, your old Chocolate Chips are still perfectly edible, because chocolate is a relatively durable food, it does not easily go bad, so you can use them for whatever purpose you originally bought them (such as baking Chocolate Chip Cookies). But if you do not trust them and think that they have deteriorated, you can throw them away. Or feed them to squirrels. Squirrels are never known to complain about the freshness of chocolate chips.

Answer 2

You can crumble them over ice cream or pudding. You can crush them and use them as a pie crust instead of graham crackers.
