10" round. Chocolate hazelnut birthday cake with chocolate cream cheese buttercream frosting. Decorations were made from white chocolate using candy molds. Writing was piped using white chocolate (I discovered piping chocolate lettering is very different from piping icing--what a booger!) Anyway, this cake was for my sister-in-law's music professor at college. All of the students in his studio got together and threw him a surprise birthday party because he's so nice and cares a lot about them.
