Cake mix - baked to form two circular cakes
Frosting (either homemade or store bought)
Licorice for whiskers - M&Ms for decoration
Jelly beans for decoration
Coconut, dyed green
You have two circular cakes, as though each would normally be one layer of a birthday cake. One is the head. The other is used the make ears and a bow tie.
Cut the two ears out of either side of the circular cake, and then the center becomes a bow tie.
Assemble the pieces, put frosting on it, and decorate it, making a face on it, etc. We used white frosting for most of it, and pink frosting for the center of the ears. Use licorice for whiskers, and put M&Ms all over the bow tie.
