Use a 2 tablespoon cookie scooper (or make two tablespoon mounds) and place on cookie sheets. It should make 16 cookies.
Bake for 11 minutes, remove from oven, and keep the cookies on the cookie sheet for at least 10 minutes to finish "baking". They will be super soft still, but move them to a cooling rack to continue cooling. If you like your cookies a tad bit less ooey gooey. Bake for 12 minutes then let them sit for at least 10 minutes before moving to a cooling rack. *If your oven runs hotter or colder adjust time accordingly.
