Using a cookie press fitted with the disk of your choice, press dough 2 in. apart onto ungreased baking sheets. Press chocolate chips into cookies as desired. Bake at 375° for 8-10 minutes or until set. Remove to wire racks. Store in an airtight container.
Editor’s Note: A pastry bag fitted with a coupler and #32 star tip can be substituted for a cookie press. Pipe dough into concentric circles or shapes of your choice.
