Cool Homemade 3D Ninja Turtle Cake

For this cake I made one large round cake, plus one smaller dome shaped cake.  The nose section was made from off cuts from the dome. After joining the three pieces together with a layer of butter icing, I iced it all in green butter icing. The eyes and mouth were cut from rolled out fondant icing.  Eyes, nose and teeth were painted on using gel  colouring. Too easy!
