Do Cookies Harden As They Cool?
Yes, cookies do tend to harden as they cool. This is because the heat from the baking process causes the sugar in the cookies to melt and caramelize, creating a soft and chewy texture. As the cookies cool, the sugar re-solidifies, resulting in a harder and crisper cookie. If you prefer your cookies on the softer side, try taking them out of the oven a minute or two earlier than the recipe recommends.
