This is one of the most fun cakes I've ever done...
and it's all chocolate!
This is called a "gravity-defying cake." It is made by using a copper tube that is run up through the middle of the cake drum. I took an online class through Craftsy.com, which was wonderful, called "Gravity-Defying Cake Designs" with instructor Lauren Kitchens. She was an excellent instructor.
Here is my Italian mother-in-law with the cake. She is so adorable!
