I made this FUN to be ONE cake for my grandson Fionn's 1st Birthday. Double layer chocolate fudge cake with a chocolate ganache filling. I then covered the cake with chocolate ganache. which I also used for the shell piping detail - added the Smarties for colour and texture. White chocolate and milk chocolate Kit Kat bars on sides. Lettering and number is made from gumpaste. The top of cake was covered with white fondant, finished with a Mickey Mouse topper - a printed edible image.
