You can't have too many recipes for chocolate chip cookies, the universal favorite. Here, brown sugar replaces the usual white sugar for deeper flavor. The dough comes together quickly and can be refrigerated up to a day before using, all the better to pinch off portions and roll into balls, without sticking to your hands (flouring your hands also helps). Once baked, you can keep the cookies in an airtight container at room temperature for up to a week.
