I use the Spritz recipe, too, and I use the press die that gives you a wide ribbon, with one side smooth and the other side with little ridges. Then, you buy Hershey's chocolate bars and break them into bite sizes about 1" x 1/2" (a bar is already divided into panes of about that size) and set them along the ribbon, with about a half an inch between or more. Then you press another ribbon directly over the top. You use a knife to gently press down and seal in the gaps between chocolate pieces. After baking, you can use those marks as a guide to cut the cookies. You can add sprinkles to the top for decoration.
My mom called these "Chocolate Pillow Cookies," and it's the only recipe I've ever used my press for!
