So I love this cake and would like to know how to call it. It looks like there is a lid on top of each tier. What would you call this and how is this made. Might be old but new to me thanks. 

The cake was made by The Whole Cake

You could e-mail them and ask.

Athey may have just put a flat layer of fondant on top
