I was only making 20 cupcakes so the task wan't too daunting, we decided on 10 chocolate cakes and 10 lemon, keeping the flavours simple, so we could please as many people as possible. After doing some online research and talking to my friend about her ideas we agreed on the 10 chocolate cupcakes having a babies face on them and the 10 lemon cakes being topped with lemon butter icing and baby themed icing figurines. They know that the baby is a boy which also made the process slightly easier as it meant we could have a definite colour scheme.
For the icing shapes on top of the lemon cupcakes I used modelling paste and various food colour pastes. I made them a couple of days in advance so that they could dry out properly. The faces on the chocolate cupcakes were just made out of sugar paste and they were very easy to do as the design is simple but at the same time, effective.
