My friend was having a big first birthday party for her daughter with a Dr. Seuss "Cat in the Hat" theme. This is what I came up with for her. The bottom tier is a 10-inch pumpkin spice cake with cinnamon buttercream filling. Middle tier is an 8-inch chocolate chocolate chip cake with vanilla buttercream filling. Top tier is 3 6-inch layers carved to the shape of the hat, also chocolate chocolate chip cake. Entire cake covered in vanilla buttercream. Decorations and hat base are mmf. tfl.
