I made this three Tier 60th Anniversary Cake for my father-in-law and mother-in-law. The bottom tier is a strawberry cake with american strawberry buttercream filling and covered in vanilla Italian meringue buttercream. The middle tier is a chocolate cake filled with chocolate ganache and strawberry preserves, and covered with chocolate Italian meringue buttercream and chocolate ganache; and it was decorated with white royal icing. The top tier is a spice cake with cream cheese buttercream filling and covered with cream cheese buttercream rosettes. The "60" on top was made out of gum paste and painted with gold luster dust.
