Keep in mind, I have 120 baking trays, and I don't use cooling racks. My cookies have to cool on the tray as the tray cools. So how do I keep them from sticking? Easy.
As soon as they are out of the oven, I simply loosen them on the pan. Move their position slightly. This breaks the seal that had been created, but you must do it when they are piping hot. If you allow them to cool, they will stick.
Some cookies, however, should not be moved on the tray, and these include chocolate chip, oatmeal raisin, peanut butter. These cookies need to firm up by cooling down. After they are set, you can remove them easily from the tray.
Happy baking from Signature Sweet Shoppe!
