Wedding cake are an art and usually served at wedding following the  dinner. 
I love wedding cake. It is so beautiful and it is nice to see the bride and groom feed each other at weddings.
Wedding cake were created to bring good luck to all guests at the wedding and the newly weds. 
It is a great tradition. My favorite cakes are the huge, multilayered ones with figurines on top.
Some wedding cakes are not edible and the groom only share an edible on between themselves.
