To keep these nice and soft, don’t let these cookies brown in the oven. Remove at 8 to 9 minutes. No longer.
If you don’t want these cookies to spread much, refrigerate for 30 minutes to an hour before baking.
Fun tip: if your cookies aren’t round, as soon as they come out of the oven, grab a glass that is larger than the cookie. Place the cup upside down over the cookie and do a little swirl and you will have a more uniform round cookie.
