How do you fix undercooked sugar cookies?

Online Answer
Once it's clear that you do have limp cookies or less-than-crispy crackers, put them back into a preheated 300° F or 325° F oven, regardless of the original (presumably higher) baking temperature. I tend to use 300° F for items that can't afford to get darker, and 325° if a little extra color won't hurt.
