Making the Ears While the cake is cooking, cut out a triangle from each cookie 2 inches long on each side. Prepare a piping bag with the grass tip and add some of the chocolate frosting to the piping bag. Gently pipe ‘fur’ on the front of the triangle by placing the tip end on the cookie, squeezing and pulling straight up (
here is grass/fur frosting instructions with photos). Repeat this to cover the entire top of the cookie. Continue to cover the sides leaving about ½ inch on each side of one of the corners unfrosted (this is to handle the ear without disturbing the other frosting; it will be completed once on the cake). Set aside to dry/harden.
