Step 3: Shape the Cake
Cut the corners off of the rectangle and reserve pieces for the tail and beak.
Level the tops of the bowl cakes to create a flat surface. Eat the scraps immediately. (you're welcome)
If you want a hollow cake, use the large round cake to mark out its placement on the rectangular cake. Then cut out a circle about 1" inside this mark (see picture 3).
Cut a circle inside the large round cake, and also the small round cake if desired. I kept the smallest circle to place on top and add height to the crown.
