How to make a really easy Train Birthday Cake

Children’s birthday parties can be fairly hard work, with lots to remember, from party food, party bags, games, music, costumes and cake. I’m all for making life easy (and on a budget), so this year instead of buying an expensive cake we opted to make our own. The small boy wanted a train birthday cake to go with his train birthday party and who am I to argue?

Train birthday cake

To make this easy train birthday cake you will need:
Three rounds of sponge cake (as described below)
Half a jar of raspberry jam (approx), or strawberry if you prefer
Two tubs of Betty Crocker Vanilla Buttercream icing
Three tubes of smarties
Bigjigs trains (see below)
One cake board (or big enough plate)

Hubs is the baker of the household, so I asked him to make three layers of sponge cake. Use your favourite and foolproof sponge cake recipe (his used 8 eggs to give you an idea of the amount of sponge we made) you want to make three round sponge cakes baked in a 25cm tin. Once baked they need to be around an inch tall.

Once the cakes are cool, put a blob of the buttercream on the cake board and place the first layer of sponge on top of that, this helps to anchor the cake to the board and stops it sliding about. Spread a layer of jam on top of the first layer. Carefully turn the second layer upside down and gently spread the flat bottom with the buttercream and sandwich in top of the jam layer.

On the top of the second layer, spread evenly with more jam and then spread buttercream on the upturned bottom of the top layer of sponge, put that on top. You should have a three layered cake in front of you which from the bottom goes…
Blob of buttercream

With me so far? Good. Now you’ve got all your layers stacked carefully, spread the remaining buttercream over the top and sides of the cake. Don’t worry about it being prefect, if you aim for the rustic look it’ll be fine. I created a wavy effect with a palette knife and the sides were rough but fully covered. If you want you can make the buttercream smooth.

Bigjigs make a sort of pick and mix name train set, I bought mine from my local toy shop Giddy Goat Toys. I bought the carriage and the letters of his name for £2.25 each, which cost me just £9 in total. This was much cheaper than buying a proper train and carriages and much more personal.

I gave them a little wash, though they’d been in a sealed box, then using a little blob of the buttercream “glued” the removable letters onto the carriages and pressed the train into the thick buttercream in the top of the cake.

Tipping the smarties into a bowl I then wrote his age in smarties on the top of the cake, then I used the remaining smarties to edge around the bottom of the cake. I was pretty pleased with my efforts.

If you do this the night before the party and leave it out uncovered overnight, the buttercream should firm up slightly and make it easier to transport. On the morning of the party I wrapped it loosely in foil and it sat in my knee in the car on the way to the party. On arrival we unwrapped it and there were no buttercream smears on the foil and it still looked good. Phew.

The cake tasted really good, but hubs does make beautiful cakes. We had lots of lovely compliments about it. It sliced into approx 24 slices, which was more than enough for a kids party.

Our lovely and quite huge train birthday cake was a really big hit, a few people thought we’d bought it (ha, always a compliment) and the small boy was really, really pleased with it and proudly showed it off to his friends. It’s a really easy way to make a simple sponge birthday cake a little bit special.
