When I am working with clients to come up with designs and ideas I like to ask contrasting questions. So you get the party cake recipient in your head and then choose your answers....sophisticated vs. fun, bold vs. dainty, loud vs. quiet....And then from this process I get an idea of the person getting the cake, while I also get design ideas for their cake.
The ideas that this cake was born from was "fun and funky without being childish". Often parties and cakes are too sweet or too goofy and childish. We wanted some strong and bold designs, and wanted to stay away from kid-like stuff. Went with a chocolate cake, vanilla butter cream, and then I finished the cake with a dark chocolate ganache. Yum! The rest of the decor is done in fondant.
