Choo, choo! The Happy Railroad is a Thomas the Train special! This double-tiered kid’s birthday cake is covered with blue fondant on the topside to look like the sky behind the train that is just about to emerge through the tunnel, while green fondant covers the bottom layer for grass. Railroad tracks race around the outer edge of the top layer of kid’s birthday cake recipe, which is just slightly smaller than the bottom one. The kid’s birthday cake topper is a numeral representing your child’s age along with a few puffy clouds. Offered by your local Las Vegas bakery!
