My cousin was having a Princess Tiana themed party for my little cousin. And my cousin wanted something that no one has done yet dealing with Tiana as a cake. So I had my daughter Tache'(future engineer) to draw me a template of Tiana and her frog. So from Tiana neck up it's yellow cake and from Tiana neck down is chocolate cake with Buttercream frosting. And yes, Princess Tiana is little more chocolate than normal. I shouldn't had added that extra cocoa power to the brown buttercream. But Princess Tiana and her frog was a hit at the birthday party.
