For his birthday this year my son asked for a Lego cake – having just been to Lego Land may have had something to do with it 🙂
A quick search online returned lots of amazing Lego cakes, many of them quite intricate. Unfortunately time was limited and I decided to go with a very simple design this time. I had bought a Lego brick silicone mould and made little bricks in different colours out of fondant icing to decorate the cake. A few Lego men were drafted in to help hold the birthday candles and the birthday boy was happy – though he was more interested in eating just the Lego bricks and not very much of the cake.
The day of the birthday party turned out to be quite hectic, and I only managed to take a few pictures of the cake.
200 ml sugar
200 ml flour
2 tsp baking powder
100 ml boiling water
Lemon curd mousse
100-200 g lemon curd
500 ml whipping cream
200 g cream cheese
150 g butter, at room temperature
200 g icing sugar
about 50 ml boiling water
1 tsp vanilla extract
Ready made fondant icing in different colours
1) To make the cake, preheat the oven to 175ºC and prepare the tin. Cream eggs and sugar until pale and fluffy.
2) Add flour, baking powder and the boiling water and gently fold together until smooth. Pour into the tin and bake for 20-25 minutes, or until golden-brown on top and a skewer inserted into the middle comes out clean. Leave to cook on a rack.
3) Next prepare the lemon curd mousse. Whip the cream until it forms soft peaks.
4) Mix the cream cheese and lemon curd, then add to the whipped cream. Keep chilled until ready to use.
5) For the buttercream icing, start by beating the butter until soft. Add half of the icing sugar and beat until smooth.
6) Add the remaining icing sugar, vanilla extract and a little bit of the boiling water, taking care not to add too much water as the buttercream shouldn’t be too sticky.
7) To assemble the cake, cut the cake into two even layers. Spread the bottom layer with the lemon curd mousse, then add the top cake layer.
8) Cover the cake evenly with a thin layer of buttercream.
9) Roll out the fondant icing and cover the cake.
10) If making Lego bricks in a silicone mould, dust the mould with corn flour before adding the fondant icing to make sure the bricks don’t stick to the mould.
