How to Make a Rubik's Cube Cake!

making a rubik's cube cake

Earlier this week my friend Sarah and I made a Rubik's Cube cake as a birthday present for somebody who is apparently a bit of a champion at them! This cake was really fun to make, although it did take us around 3 hours in total due to the separate layers, meaning we didn't finish til around 11pm! Whew! If you'd like to have a go (they're also good for 80's themed parties) here are the instructions. (Warning: a lot of sugar is involved... but hey that's part of the fun!)



For the Victoria Sponge Cake

225g/8oz butter or margarine, softened at room temperature
225g/8oz caster sugar
4 medium eggs
225g/8oz self raising flour
2 tsp vanilla extract
milk, to loosen

For the chocolate ganache coating

250g good quality dark chocolate, chopped
250ml double cream
1 tablespoon dark rum (optional)

For the buttercream

140g/5oz butter, softened
280g/10oz icing sugar
1-2 tbsp milk

Other things you'll need:

Ready to roll icing in 6 colours (you can buy this in packs from Lakeland - a lot easier than colouring your own icing individually!)
Square baking tin
Rolling pin
2+ mixing bowls

1. Firstly you'll need to make 3 Victoria sponge cakes, to make the layers of the cake. We used this recipe though you may need to slightly increase quantities. You can either divide the mixture into three cake tins or bake it in three stages using the same tin, as we did. When each layer is done, leave to cool while you make the icing.

We had a little helper...

2. Next make the chocolate ganache. This is pretty easy to do, we followed this recipe and added some rum to taste. Yum!


3. Next dust a chopping board with some icing sugar and roll out each icing colour to make a rough square. We cut a square out of paper to use as a template to ensure each square was the same size. Now cut the large square into 9 smaller ones, to make up the separate coloured squares!

4. Now to make the butter-cream icing to put in between each layer! This recipe works well.

5. When all the layers of the cake are cool, assemble them and trim off the edges so that the cake is more square-shaped. (We had to add an extra layer in the end, to make it a bit taller from the bits we'd cut off!)


6. Now add the butter-cream between the layers. Pour the ganache icing on top of the cake and spread over the edges.


7. Finally, stick on the coloured squares and you've made your Rubik's Cake. Hurrah!


  1. So very impressed

    What a brilliant cake idea - although I can see why it takes a while to make!

    Well done :)

  2. AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  3. Oh my gosh that is a super awesome cake!

  4. So absolutely disgusting to have the cat on the counter during the baking and decorating. I can't believe you would post pictures of that. So gross!

    1. Hi 'Anon' thanks for your comment. It's a fair point, but i was making the cake in a friend's kitchen and her cats like to see what's happening at all times!
