Why make this cake?
The Rubik’s cube is close to my heart as I am a child of the eighties and the Rubik’s cube always brings me back to a time of joy and wonder. It’s hard to imagine kids today being as fascinated as I was by such a simple but clever toy. I wanted to make a cake that epitomizes this ingenious and timeless invention. I knew it would have to be a clever cake that would make you question how it was made. Thankfully I had the help of my other half and his engineering brain to assist with the planning and general maths of this cake. It took an entire day to make but was definitely worthwhile, especially when we cut the first slice.

Step 1: Baking the cakes

2_layout.jpg
Pre-heat the oven 180 degrees Celsius. Grease and flour a Battenberg tin. My Battenberg tin was 8inches x 6inches and had 4 individual sections to put the different colours.
You'll need to make three cakes and each cake will comprise two of the colours needed - white/yellow, then red/orange and finally blue/green.
Cream together the butter and the sugar until it becomes light and creamy. Gradually add the beaten eggs. Then, carefully fold in the sieved flour.
Next split the mixture to make the two different colours. Take half of the mixture out, and place in another bowl. Add a few drops of food colouring to one batch. To the other half, add a few drops of a different food colouring.  For the white sections of the cake. I slightly over-beat the egg mixture and didn’t add any colouring. This achieved a pale off-white effect. Spoon the mixture into the separate sections of the tin. Place in the oven for 30-35 minutes. To test if it’s ready place a clean knife through the center, the knife should come out clean when it is fully cooked. If the cake rises over the tin, use a serrated knife to even off the top. Let the cake cool in the tin, once fully cooled, remove from the tin and place on a wire rack.
Repeat twice using the same method, ingredients and remaining food colours for the red/orange and blue/green cakes.
Optional: You might want to flavour the cakes as well as colour them. I used lemon zest for the yellow, orange zest for the orange and vanilla for the white. You want to find complimentary flavours that will work as a cake, so it's probably best to resist the temptation to put mint flavouring in the green as it could taint the whole cake.

have you thought of making it w. ricecripy treat and food coloring?
Aegian2424 says: Jul 29, 2011. 12:20 AM
have you considered making every color taste differently?
stasty (author) in reply to Aegian2424Jul 29, 2011. 2:46 AM
I did, I thought of making the Green cake mint flavoured but I thought it might make all other pieces minty too (even with the jam insulation). Maybe blueberry for the Blue and Raspberry for the Red?
Aegian2424 in reply to stastyAug 3, 2011. 4:12 AM
blue would be blueberry, white vanilla, red stravberry or cherry or raspberry, green could be lime, yellow pineapple or lemon, and do I have to say what flavour would orange be? :D

My friend is obsessed with Rubik's cubes. (He's solved a 7x7 and can finish a 3x3 in under a minute. He even mentioned Rubik's cubes in his graduation speech.) Anyway, I'm making this cake for his birthday, but instead of using the battenburg recipe I used boxed white cake mix and jello to flavor and color the cakes.
For red I used strawberry, orange orange, yellow lemon, green lime, blue blueberry, and the white is plain. I also colored my cream cheese frosting (homemade) black :D

Oh. My. Gosh.

This is fabulous! I've seen checkerboard before, but
this 'takes the cake', pardon the pun.

So much fun, so colorful! Bravo!

Best cake idea EVER! I love the attention to detail - making sure each piece is different goes above and beyond the call of duty.

Wicked cool!!  :D

Cool cake. I need to remember that one for my next party.

I saw this as an article on the MSN home page. Good work.

Wow!
I had a go at making battenberg cake the other day and that was too stressful for my liking.
You must have a lot of patience!

@ Stasty; Hi! This is the triumphant birth of a new discipline: Technocookology :)

When I saw the first picture, I thought, nah, she couldn't REALLY make every slice different, could she? Then I looked and read, looked and read some more, and, OMG you did!

I am sending this to my sister-in-law and daughter, who both cook. I don't promise they'll attempt this, but they WILL be impressed.

Cheers! :)

WOW!

This is awesome! Going along with the citrus theme for the yellow n orange, how bout a bit of lime zest for the green? And I like the idea of rasberry n blueberry for red n blue. Maybe a bit of vanilla for the white?

Wish I had the patience to make this! I'm going to pass it along to my niece, she's the cook in the family.

Love it!

Fascinating concept! Only problem is that here in the USA we don't have access to marzipan to cover the cake, nor the cake pan. We have to use frosting or fondant. That would be the only drawback in making the cake for those of us across the pond.

For those of us here in the states I did find a source for the cake pan here: http://fantes.com/cake-pans-sheet.html There are many great recipes for marshmallow fondant on instructables along with some very fantastic cakes.

I have seen Marzipan in Wal-Mart and small grocery stores in Oklahoma so it is available in the USA. You could look online at the Walmart site and you might be amazed.

Great! I saw this just in time for my birthday!

Awesome!
AngelBunny says: Jul 28, 2011. 12:57 PM
That is too amazing! Great job!!!! I can't wait to show this to my sis-in-law so she can attempt it for my Rubik's loving brother!
stasty (author) in reply to AngelBunnyJul 28, 2011. 1:17 PM
Please ask her to send me a photo, I'd love to see how she gets on.
AngelBunny in reply to stastyJul 28, 2011. 2:17 PM
His birthday in later in the year and they have 18 month old twins, but I know she will practice ahead of time, so I will pass on anything she sends me! =)
stasty (author) in reply to AngelBunnyJul 28, 2011. 4:39 PM
That would be great :)
AngelBunny in reply to stastyJul 28, 2011. 5:15 PM
You're a doll, I'm sure she will send pics!

I think this is the first cake I have seen where you need a spreadsheet to make it...
