This was done on a 12in base yellow cake with the cow made using the 3D lamb pan and the same yellow cake used for the base cake. I used the "durable cake for 3D...cake" recipe. All buttercream, the black frosting is chocolate bc. This was done for my sisters 17th birthday. The cake and I made a 130mile trip for delivery - made it without damage Yay! She loved the cake!
