Have you always wanted to know how to make a lego cake? Well I will now reveal all!

This 3 tier ( 5″ / 8″ / 11″ ) square cake will serve 100 dessert portions.
The top two tiers are Gluten Free Orange and Almond filled and covered with white chocolate ganache and the bottom tier is a Moist Chocolate cake filled and covered with dark chocolate ganache. All three tiers are then covered in fondant.
Quantities of Fondant

3 Kg white fondant to cover cake and make some lego bricks
750g red fondant
750g yellow fondant
750g blue fondant
750g green fondant


3 thin set up boards 5″, 8″ and 11″
17″ or 18″ cake board
Lego builders and chefs + Lego Bride and Groom topper ( purchased online from the UK )


Recipe for 5″ and 8″ square Orange and Almond cakes
3 – 4 unwaxed oranges
12 eggs
630g caster sugar
1.5 tsp baking powder
630g ground almonds

1. Scrub oranges well and leave them whole. Put them in a large pan with enough water to cover them. Put a small plate on top of the oranges to keep them submerged. Bring to the boil then reduce heat and leave to simmer gently for 1 hour until very soft.

2. Drain oranges well, then put back in the pan and leave until cool enough to handle. Cut in quarters, remove pips, then puree in blender.

3. Use electric mixer to beat eggs, sugar, baking powder and a pinch of salt until pale and creamy. Beat in the almonds and 630g of the orange puree. Leave for 20 mins and preheat oven to 180C. Pour batter into the two pans and check with a skewer that they have the same depth.

4. Bake for 30 mins  The cakes will have different baking times as they are different sizes so keep checking every 10 mins or so until golden brown and a skewer comes out clean.

Recipe for 11″ square moist Chocolate cake
175g cocoa powder
21 tbsp boiling water
11 eggs
14 tbsp milk
613g Self raising flour
4 tbsp baking powder
350g soft butter
1050g raw caster sugar

  1. Preheat oven to 180C.
  2. Put cocoa and boiling water in a large bowl and mix to a paste.
  3. Add remaining ingredients and beat till combined. Do not over beat.
  4. Bake for 30 mins. The cake will take a lot longer than 30 mins to bake so keep checking every 10 mins or so until risen and shrinking from side of pan.

Recipe for ganache

600ml pure cream
1.7Kg dark chocolate

White chocolate ganache
400ml pure cream

Preparing the Lego

I decided to make the Lego the same size as actual Lego but this was a big mistake as it took forever to make all the bits and pieces. You could make the Lego 50% bigger and save lots of time and the cake would still look good. I coloured my fondant to match actual Lego bricks. I used a drinking straw attached to a syringe (with strong glue) to make the little studs and I used a square cutter that was approximately the size of two bricks and then simply used a knife to cut them in half.




When covering the middle and bottom tiers, I rolled the fondant a little thicker than normal so that the bricks would appear to be ‘under’ the fondant. I cut the fondant half way along the side on all tiers to give a uniform appearance.


The middle tier

The top tier does not have any fondant cut away on the top so make sure you don’t get carried away and treat it like the other two tiers.

The top tier

Start with the cake board and place the white fondant first leaving the area to be covered in bricks free. Fill in with the bricks and then the studs making sure that you have covered the area plus extra which will be under the bottom tier an inch for a neat look. When the board and the bottom tier were dry I placed the bottom tier right in the middle of the cake board. The middle and top tiers were not placed in the middle as they were placed a little more to the back corner so that there was lots of room at the front for Lego people and for the rolls of fondant. If using a dowel as I did you will need holes in your set up boards and the top two tiers will need their holes off centre so take some time to get those positions correct right at the start. I also used internal pillars to hold the weight of the tiers.




Roll the fondant up like bandages and attach with some icing using a piping bag.

  1. Hi Bernice,
    That Lego cake is so imaginative and creative. WOW!
    How long did it take you to make it?
    We met briefly at a networking event last year at Palm Beach Sports Club. Just found your card today and had a look at your work.
    have a terrific Tuesday!

    1. Hi Damian, thanks for you lovely comment. The cake took over 40 hours to make on a very busy week full of wedding cakes. Luckily my daughter made all the lego bricks for me or I would still be making them today! Cheers Bernice
