Rubik’s Battenburg Cake

Hungarian Ernő Rubik invented the Rubik’s cube in 1974. He was born on the 13th of July, 1944. Cake designer Vicky and her other other half set about making a birthday cake, worthy of the great man, himself. Battenberg cakes are constructed of rectangular pieces of alternatively colored Victoria sponge cake, sandwiched together by jam and held together with walls of marzipan. We decided that the different pieces of cake could by dyed the traditional six colours of the Rubik’s cube – white, red, blue, orange, green and yellow.

Then to make the cake a little more Rubik’s like, they decided to have each slice of the cake reveal a different combination of colored squares, just like a Rubik’s cube. To achieve this, they cut the colored rectangles of sponge into different lengths. This was definitely a case where I needed the engineering mind of my other half to figure out the maths of this cake. It took a little planning to get it right, however I think it might just be a worthy birthday treat. I’m not sure if Ernő has a sweet tooth but hopefully he might enjoy this puzzling cake.
