My first cake to defy gravity!! The bottom tier, or "garden" is an 8in chocolate cake with chocolate buttercream filling, and vanilla buttercream for decoration! The top tier is a 4in vanilla cake, and has a fondant figure sticking her head out of a window, letting her hair flow down! I used a food safe PVC pipe as a center support system for this cake, which is covered in Rice Krispies treats. The roof of the tower is sculpted from RKT as well, and is covered in fondant! I am very proud of this cake, my first time making a support system of this kind and boy was it strong! I think we could have held this baby upside down and she wouldn't have moved a bit!
