These festive cookies are loosely based on the Greek Easter specialty koulourakia. Use egg-shaped cookie cutters to create these Easter "eggs" (we ordered ours from H.O. Foose Tinsmithing Co.). Tint the frosting any color you like (or use several colors). Spread it onto the cookies, or spoon the frosting into a zip-top plastic bag, snip a small hole in one corner of the bag, and pipe the frosting in designs of your choice. The kids can help with the fun.
