General Instructions for Baking Cookies

Some cookie recipes involve baking more than one sheet or pan of cookies at a time. This can lead to uneven baking, since the cookie sheets must be placed in different locations in the oven. Remember to do the following about halfway through the baking time:

Also, if you notice that cookies frequently burn on the bottom when baking in the lower third of the oven, stack two sheets together to insulate the cookies from the excess heat. That should prevent the bottoms from burning. The double-pan arrangement should always be on the bottom rack of the oven, so remember to leave the extra pan there when you switch the two regular pans.
