My son LOVES trains. For the past 3 years of his life, I have wanted to make cupcakes with a very classic train look for him. This year, I created cupcake wrappers that actually looked like circus train cars and topped the cupcakes with animals and my son as a train engineer. I rainbow swirled the icing to follow along with the circus look of the train cars. They turned out adorable and all the kids loved receiving their own train car with circus animal.
