These look very cool. We didn't have the rectangle cookie cutters so we used round ones with a circular window. Still, same effect. We did the recipe exactly as suggested. The problem was the Jolly Ranchers melted a bit underneath the regular cookie, so the underside of the cookie was covered with a thin sheen of Jolly Rancher that was very tough to bite. Another option might just be a thumbprint filled with Jolly Rancher so it didn't leak. Anyway, will not make again.
