Place the cookie dough in a large gallon size Ziploc bag. Without sealing the bag, use a rolling pin to roll out the dough until it fills the bag completely and it is a flat 1/4-inch-thick square. Seal the bag, pressing as much air out as possible. Place in the refrigerator to chill for at least 2 hours, or up to 2 days.

Once the dough is thoroughly chilled, remove the bag from the oven and carefully cut the bag to release the dough. Transfer the dough square to a clean surface. Cut the dough into about twenty 2-inch squares. Transfer the squares to the prepared baking sheets.

Bake the cookies until they have set and are fully baked, about 15-20 minutes. They will not change color, or turn a golden brown color. You will know they are done when they are no longer wet-looking. Remove the cookies from the oven and transfer on a cooling rack to cool completely. Enjoy!
