Isn't it gorgeous? It uses the Petal Crafts Topsy Turvy Cake Pan:
The round pan retails for $85.95 and the square pan for $99.95. I want them both! lol Now I am trying to justify spending that money so I can try to make it as a birthday cake for the kiddo. Maybe I'd get super lucky and find it at Goodwill? Doubtful. lol If you've tried it out, were you pleased? I know there is no way my cake would ever look as good as the one above, but hey, practice makes perfect!
