My nephew gave me a keychain with a lego figure attached and asked if his cake could look like that Lego Man. Head is made of RKT covered in modeling chocolate. The body arms and legs are made of cake. The cake was stacked, carved to make the body shape and then covered in modeling chocolate and buttercream to hold the shape. Be sure to make the RKT head at least a day ahead so that the cylinder shape stays in tact. The Lego hands are also RKT covered in chocolate.
