How can I make my Oreos crispy again? Someone1 didn't re-close the Oreo bag properly, and now the remaining cookies are kinda... not-quite-crispy. They're not soft, but they have this chewy side to their crunch.

If these were ordinary cookies, I'd pop them in the oven for a few minutes, but I have this thing where I like my creme filling to be inside my cookies, not melted all over the baking sheet. I'm funny that way.

Is there any way to make these cookies crispy again, or do I make the offending party2 eat this bag and get a new bag for, um, the non-offending parties?

If it makes any difference, these are peanut butter Oreos.

Put the bag in front of an air conditioner for a few minutes. Worked like a champ for Oreos and chips that went stale over a humid weekend in a desk drawer.

This was a window unit- I arranged to blow the cold air into the bag. Was amazed with the results.
