two birthdays in one

How to combine two birthdays into one cake? This cake was ordered to celebrate the birthdays of a mom and her son who were visiting some friends. They wanted a small number of servings with a cake in a train theme to celebrate Matthew's 5th birthday but also wanted to incorporate Maria's (mom) birthday. This cupcake cake was made using 17 cupcakes - 10 for the train cake and 6 for the flower. This cake also shows how you can make a cake to go along with a licensed character theme without violating any copyright laws - the cake was designed for a train theme and the customer purchased a train to be placed on top of the cake (and also as a present for the birthday boy). Cupcakes were half white sour cream cake and half double chocolate sourcream, iced with American buttercream. The "5" was made from white chocolate colored red.
