Of course - we love to cook chocolate chip cookie dough in ours. Preheat waffle iron to medium-low. Generously spray the top and bottom of the waffle iron with cooking spray. Using a cookie dough scooper or a tablespoon of the dough, roll into balls and flatten slightly and place in the waffle maker. Work in batches, place 1-2 cookie dough round(s) onto each section of the waffle iron, close gently and cook until slightly crisp, 3 to 6 minutes. YUM!
