Scoop the chilled dough into 2-tablespoon-sized balls and place them on your prepared baking sheets, keeping them about 3 inches apart. Bake for 8 to 10 minutes, or until the cookies have spread and developed a shiny, cracked surface. They'll still be soft when hot but will firm up as they cool.

Allow the cookies to cool completely on the baking sheets before serving or storing.
