Scoop dough out 1 TBS at a time onto prepared baking sheet. Space scoops 2 inches apart, cookies do spread slightly.
Shape each scoop into a tight ball. Bake at 350 for 12-14 minutes or just until golden
Remove cookies from oven. Cookies will be very soft but will firm up as they cool.
Let cool on rack 12-15 minutes or until cookies are firm enough to handle. Transfer to a wire rack and allow to cool completely. Store leftovers in an airtight container at room temperature.
