This was for my son's class to celebrate summer birthdays. The theme of the class is Dr. Suess, and I've been wanted to make one of these cakes all year. I finally got the chance! White cake with buttercream. The characters and sign are gumpaste, and I used edible ink markers to draw and color each piece. The kids were really excited when I brought it in the room, and the teacher loved it,too! Makes it all worth it! TFL!
