I had the pleasure of making a Hello Kitty cake & cupcakes for a first birthday party a few weeks ago.  This was a two-tier 10″ & 12″ inch cake covered in three colors of buttercream, and embellished with intricate modeling chocolate and fondant work.  The cake flavors were fresh raspberry and cream cheese raspberry filling, and chocolate chip marble and Oreo cookie filling.  The cupcakes had little Hello Kitty bows made of chocolate.  Of course all cakes were made from scratch!  Happy 1st Birthday, Kaya!
