*The cookie dough can be prepared and rolled into balls in advance, then frozen. Lay the balls of dough flat on a plate or baking sheet and freeze until solid, 1 hour. Then you can transfer the balls of dough to a ziplock bag and keep frozen for up to 3 months. To bake from frozen, simply place the frozen cookie dough balls on a parchment lined baking sheet and bake at 350 for just slightly longer, about 12-14 minutes.
