In advance: Make trunk and ears. Prepare and roll out cookie dough. Use pattern to cut out trunk and 2 ears (flip pattern for 2nd ear). Bake and cool. Attach Lollipop Sticks to back of ears using melted candy; allow 2 in. to extend at bottom to insert into cake. Let set.
Bake and cool cake. Trim ear areas to 1 in. high; trim edges as needed to match shape of cookie ears. Ice smooth inside of ears and trunk opening on cookies and paw pads on cake.
Pipe tip 5 dot eyes; flatten slightly with fingertip dipped in cornstarch. Add tip 2 dot highlights.
Cover cake with tip 16 stars; position trunk and ear cookies and trim with tip 16 stars. Add tip 2 outline stitching details.
*Combine Violet with Pink and Royal Blue for violet shown. Combine Pink with Royal Blue for pink shown. Combine Brown with Red-Red for brown shown.
The star tip creates the most celebrated, easily accomplished decorations! The serrated edges of the star tip make ridges in the icing as you squeeze it out. Because fill in requires so much piping from the same bag, keep replenishing icing in bag.
