Bake cookies for 8-10 minutes, until just set. You don't want to overbake them. Nothing sadder than an overbaked cookie.
You want to bake the cookies just enough so they are set, slightly golden brown, but still look a tad underbaked. Rule of thumb: if it looks done in the oven, it's going to be overdone when it cools down.
Store Cookies for up to 4 days in an air tight container at room temperature.
