Preheat your waffle iron and spray with non-stick spray.
I put 4 pieces of dough onto my small iron at once. I let them touch so that when I closed the iron it would form one large cooking. You can do it however you like. One at a time, two at a time, whatever works for you.
Close the lid and let cook 3-6 minutes or until starting to get dark.
Turn off the iron and let cool 5 minutes before carefully removing the cookie.
Let cool completely. The cookie will get crunchier as it cools.
Continue cooking by turning your iron back on and reheating it before adding more dough.
Total cook time shown is for 6 large cookies, each made from 4 sections of dough. You can make more, or less.
