My 3 yo boy loved Barney and Thomas Train. I couldn't decide which cake to do, so decided to put 2 characters on the cake. The figurines were from fondant. Originally, I was going to do fondant covered cake. But due to a very hot Melbourne weather that day, I ripped the whole covering and changed to buttercream. It wasn't the best cake for sure, but my birthday boy was over the moon as soon as he saw Barney and Thomas :) Priceless...!
