Did you cover the whole cake in the fondant and then cut the slice of cake out or do you cut the slice of cake out and then cover the whole cake in fondant?Also, what about the filling? Do you need to make sure the filling is sturdy? I want to make this cake for my birthday, but was planning on doing a cannoli filling. I didn't know if that would work since I would be taking a "slice" out of it. What are ya'lls thoughts?
