I promised my son that I would send Thomas cupcakes to school with him on his birthday. We already had his party which was dinosaur. I only had green icing left and did not want to make new icing, so I had to come up with something using the green. I came up with these. Railroad tracks on each cake with a unique train sticker on each along with leftover chocolate rocks I had used on the dinosaur cake. I raided my son's sticker book to make toppers. He loved it and helped me place each one.
