I did this cake for the Threads Cake Contest. You had to re-create a t-shirt design. I carved the milk carton out of 2 11x15 vanilla sheet cakes that I filled with buttercream and stacked and cut into 4x4" squares. I put a plastic dowel in the middle of them to support the cakes and keep them standing. The details on the cake are made from fondant. The cookie is made out of fondant. I used gumpaste to make the word bubble. I hand painted the words with brown food color. The arms are made out of wire. The cookie's feet were skewers.
