Witch Hat Cookies: One of the easiest Halloween tricks (and treats!). Place a Hershey’s Kiss on top of a Keebler Fudge Strip Cookie and you have a little hat. Use the little tubes of frosting you can buy in the grocery store baking isle. Pipe a ring around the outside of the bottom of the kiss and press onto the cookie. It will squeeze out and make the ring around the kiss. Then pipe on the bow.
