New York Cheesecake Cookies from FoodNetwork.com made these a ton. recipe turns out perfect if you let the butter come to room temp first. I measure the cookies to be 30g and then i get 16-17 every time. I zest a whole lemon and people think it's lemon cheesecake - so if you don't want that much flavor, go easier on the zest. I haven't really played around with other flavors.
