You could also use just two cake layers and slice in half, but only if they are large enough to do so and you trust your cake-slicing skills to be even...
Lego cake
Serves: 24
Prep time: At least 3 hours
Cooking temp: Depends on cake (ditto for time)
Ingredients
2 different coloured cakes of two layers each (we made red velvet and vanilla cake) Preferably with leveled tops
Cream cheese frosting and vanilla icing (again it can be made or bought. If you make it, use:
- 450g cream cheese, softened
- 125g butter, softened
- 250g sieved icing sugar
- 1 teaspoon vanilla extract
and literally just mix together in a bowl. You can use this on the inside too, or use vanilla butter cream (I tend o make this up as I go along, adding butter/icing sugar/vanilla extract to a good consistency - like thick double cream)
Packet (1kg) of royal icing
Red and green modelling icing
Lego figures
Method
- Use a round cookie cutter to cut out the centre of each cake and remove. The cakes should be completely cold and on a hard surface. Then, cut out a slightly larger ring concentrically around this - we used a bowl for a guide and cut out with a knife. Small dinner plates should work too.
- Each layer of cake should now be composed of two rings and a circle from the middle. Construct the bottom layer: take the outer ring of the vanilla cake, for example, and place the smaller red velvet inside. Finally fill the middle hole with the circle of the vanilla cake to form a target-like pattern.
Yes, I know this is the opposite way around.. - Cover the top with the vanilla icing
- Construct the next layer on top in the same fashion, but in the alternate colours - i,e, with the red velvet as the larger ring. You may want to make all these rings before placing on the cake and simply lifting on top with a large palette knife and one other person to help. Again, icing on top and repeat with the last two layers (don't put any icing on the very top, yet).
- Leave this tower of cake to set. Roll out the red and green icing on grease-proof paper to about a 1mm thick. Use a sharp knife to cut away the rough edges to form a rectangle. Using a lego brick for scale, cut out the sides of the bricks (we used a 2x4 brick and scaled it up by factor two to give a width of 2cm and a length of about 6cm).
- Using a palette knife, ice about a quarter of the side of the cake using cream cheese icing. Ensure it is smooth.
- Arrange alternate green and red "bricks" up the side of the cake, sticking against the icing.We used a half brick at the start of every other row to give the overlap of a wall effect.
- Re-roll the excess icing and repeat the scaling up for the top of the brick (the part with the studs) (ours was 3 by 6 cm) ice the top quarter in a wedge like shape, to link up to the bricks down the side. Cover with the icing rectangles again.
- Ice the rest of the cake (don't get it on the green and red). Roll out your white royal icing until it is about 3-5mm thick and roughly rectangular. Cover the cake (easier said than done, we had to do it in three parts and smooth over the intersection with water; but by all means try in one piece).
- Use a sharp knife to cut away where your green and red icing is, just up to the edge but not so you can see the cake below. Smooth down the rest and cut off any excess around the base.
- Use the left over red and green (yes, you will still have some left) to make the studs of the lego bricks on top of the cake. use a bit of tap water to make them stick to the icing.
- Roll out the white icing again to a steep sided triangle (cut away the edges with a knife to give sharp edges). Starting at the base, roll the triangle up to form a croissant-like shape. Place behind the triangle of red and green bricks on the top of the cake, as if it is the 'snow' which has been rolled back from this wedge of lego!
- You can arrange christmassy lego figures around as if they were working on clearing away the 'snow' and doing generally christmassy things like putting up a tree. We made fondant shapes in alternate colours using the red and green icing and used this to ring around the cake, and little presents to go on top of the snow pile! (wash the lego well first...)
- Enjoy the fabulous creation which gets even better when you cut into it... It's got checks!!
