Birthday cake for three

A repeat 'customer'. I have made a number of cakes for her. She is celebrating the birthday of three family members. She gave me the invitation and little other direction except for the flavour of the cake-chocolate. So....here we are. It is a chocolate cake 9 x 13 on the bottom, with a 7", two-layer cake on top. All the decorations are in buttercream-yum!
