Now is the time to chill your cookie balls (covered) in the frig. If you're pressed for time chill a minimum of 30-45 min.
Ready for baking - Place your cookies in a row (properly spaced apart depending on size) on your cookie sheet lined with parchment paper.
In a preheated oven - Bake 10-12 minutes until light to golden brown on the top and around the edges. Careful not to overcook as the cookies will still cook on the pan after being taken out of the oven.
Let cookies sit on the pan for 30 sec. They will go down a bit. With your spatula transfer cookies to your drying rack to cool.
Cool and enjoy and/or freeze extra to have for another time. See notes below.
