Small children can be fascinated by the speed, power and noise of trains. For some kids, a train-themed birthday party is the only way to celebrate their special day. Make your youngster a train cake and cherish his delight in simple things.
Prepare the cake mix according to the directions on the package.
Grease the train cake pan heavily. If you use cooking spray, make sure to get every nook and cranny on the pan.
Pour the batter into the pan and bake according to the directions on the box. When it is done, unmould the cake by holding a tray flat against the cake, then flipping them over together. Slowly lift the cake pan off the cake, so as not to break off any part of the cake. Allow the cake to cool fully.
Using the spatula, coat the entire cake with a thin layer of white frosting. Do not spread it thickly, or you will obscure the details of the train.
Mix food colouring with small amounts of white frosting to get your desired colours. You will need at least two colours for your train; one for the body and one for the accents. (Use more colours for a brighter, more creative train.)
Using your icing syringe or pastry bag with a star-shaped tip, pipe stars to cover the engine and freight car, leaving the windows empty. Switch to a round tip, and pipe a contrasting colour around the edges of the train for the wheels, and to pick out any other details you would like to emphasise. You can also use this tip to write your child's name or age on the cake.
Add small candies, such as gumdrops or M&Ms, to the cake. Use them for the centres of the wheels, the freight in the freight car, or around the edges of the cake for extra sweetness.
