Bake cake according to box instructions, using two greased 8×8 inch or 9×9 inch round baking pans. Let the cakes cool for a few minutes before transferring to a cooling rack to cool completely.
Frost the ears and bunny head with the frosting and then lightly coat the frosting with shredded coconut. Add food gel (color of your choice) to a small mixing bowl and mix in the remainder of the frosting to frost the bowtie.
