I did this cake for my Birthday Cakes 4 Free - MN kids - for October birthdays. This pattern is included in the Wilton 2010 yearbook and was a lot of fun to do. The haunted house topper is royal icing. The cakes were 10" chocolate filled with chocolate ganache and buttercream, 8" white filled with buttercream, and a single 6" chocolate layer - all covered with MMF. The cupcake toppers are fondant. The piping work is buttercream. Thanks so much for looking!
