From 2 round cakes, cut a circle from center of 1
and cut 8 wedges from outside circle. Cut a square from 1 leaving 4 pieces, which are used for the ears. I trim the top from 4 of the feet wedges so other 4 will sit on top better.
My cake mix made 3 layers so I cut a circle/square for a bunny face leaving the outside for ears and wedges that I used for a Bow-Tie. Picture in back.
