Buttercream iced 10" and 6" cakes -one was chocolate/chocolate chip and the other was white almond sour cream. The mushroom was make from half of the Wilton ball pan and two 4" cakes and covered in fondant. All decorations are fondant (except the Mario, Luigi, and Yoshi which are toys the birthday boy got to keep.) This cake was a lot of work but a ton of fun to do :)
