Rubik’s Cube Cake – Surprise Inside Cake!

September 27, 2014 by Jenn

Rubik’s cube has been around longer than I have been alive, but it’s still a popular toy that exisits in many stores.  I was pleasantly surprised to learn that, and was quite shocked to be able to find one in the store on my first try.  

The point of the Rubik’s cube puzzle, is to have each side of the cube (9 squares) be one solid colour.  You have to do that without taking off the stickers!!  Unfortunately the new cubes don’t have the stickers, so there is no cheating by way of the 80’s!  

I’ve never had the luck of being able to solve it, but in all honesty, I haven’t really tried.  I made this cake because I think it looks cool!!  I know there are genuis’ out there that have actually tried to solve the puzzle and CAN solve it!  I applaud you!  Apparently, the current World Record is held by a gentleman in the Netherlands and is attempt was completed in 5.5 SECONDS!!!  I can’t even imagine how he could do that!!  It takes me 5 seconds to figure out how the thing moves. 

Making this cake is a little time consuming, but the WOW factor when your guests cut into it will definitely cake it worthwhile! You can prepare your cake batter ahead of time, as well as prep your fondant squares.  The cake batter should be coloured in the colour theme of the Rubik’s cube- red, orange, yellow, white and green.  The fondant squares work best if they are a little bit pliable, but I ended up putting on some that were rock hard, and they worked fine too.  The hard ones don’t mold to the side of the cube as well, so some of the corners stick out.  

When you’re lining up the rectangles to make your cube, make sure you’re paying attention to the side the will have the 9 blocks shown when the cube is cut.  Otherwise, if you cut on the wrong side, you will be shown only three rectangles.  Other than that, making this cake is pretty fool-proof!!  Unlike the Rubik’s cube itself.  

Rubik’s Cube Cake 

Ingredients and Materials:

  • Black buttercream
  • Vanilla cake batter colored in 6 different batches (red, yellow, orange, blue, green, purple)
  • Fondant (red, yellow, orange, blue, green, purple)
  • Small rectangle 12 cavity pan (rectangles are 3″x 1″) Get the Rectangle Silicone mold here.

Rubik's Cube Cake

Procedure:

  1. Prepare and colour vanilla cake batter. Fill cavities 3/4 full, and press batter into the cavities to ensure that no bubbles will be in the cake. 
  2. Bake at 350F for 25-35 minutes, or until the centre cavities are completely baked through. Allow to cool completely on a wire rack. Repeat until all batter has been baked.
  3. Once cakes are cooled, trim the excess cake off to shape a rectangle. You will need 9 rectangles to complete one cube. 
  4. Using black buttercream, attach the 9 rectangles together to form a cube- three rows of three rectangles. 
  5. Cover cube entirely in black buttercream. 
  6. Roll each colour of fondant out thinly, and cut out squares using a square cutter (1″x1″) or using a fondant roller/knife etc. 
  7. Add 9 squares to each side of the cube, and you will need 45 in total per cube. 
  8. Repeat until all of your cake batter and rectangles have been assembled to form cubes.
  9. The cakes can be stored in an airtight container in the fridge for 2-3 days.

    Hi Jenny,

    I’m due to give this a go soon (Yay!). I practiced using the silicone mould last night… And it was a disaster!!! All the cake just stuck in the mould!
    Any advice on how to use these moulds?

    Cheers from London!

    Can i use colored white chocolate on the outside as the little squares instead of the fondant? I’m not very fond of fondant., if so what are your recommendations.

    • Jenn says
      July 9, 2015 at 3:33 pm

      You can do it however you want to, but I recommend fondant.

    Question:

    I am going to make this cake for an school project!! But I don’t have an the cavity pan and I don’t really want to buy it just for this. Also I don’t want to make a hole cake for each color either. What should I use to make the rectangles???

    • Jenn says
      April 26, 2015 at 1:26 am

      Yes, you could do it that way. Just make sure to cut them evenly.

    Can I use Betty Crocker chocolate frosting instead of buttercream ?

    • Jenn says
      December 7, 2014 at 3:44 am

      I find that premade icing is too soft, but you might be fine working with it. Good luck.

    My son is rubik’s cube crazy so I will try and make this cake for his birthday. Can you recommend how I can make it a bigger cake so I don’t have to make a whole bunch of them for his birthday party? Do you know if there are rectangular molds that are bigger available?

    Are the Americolor gels available at Michaels?

    • Jenn says
      December 7, 2014 at 3:47 am

      Maybe try slicing up a rectangle or square cake instead. It’s my experience that Americolor is not available at Michaels.

    Want to try this out for my dad’s birthday. He is a big fan of puzzles. What quantity of cake batter did you use and how many cakes did it make?

    • Jenn says
      October 8, 2014 at 4:52 pm

      I don’t have those measurements, sorry. I make large quantities to make a variety of videos at a time.

    This looks really cool. My husband saw the video while I was watching it and want me to try and make it.

    Some questions:

    1. Do all the different coloured cake batters taste the same?
    2. I don’t like black buttercream. Can I use purple or brown instead?

    • Tori Walton says

      You could do, but you wouldn’t get the same effect and realistic-looking rubiks cube

    Hi there! I’ve been following you for awhile now and always wonder what colour gels you use to get your colours so vibrant. I’m a Canadian too (as you are, correct?) and have access to the Wilton colours but I’ve heard that the Americolor gels are better. So, just wondered what you use? Love this cake, by the way! So colourful! (Also, where/how did you get your black buttercream?). Thank you!!

    • Jenn says
      September 29, 2014 at 11:56 pm

      I use Americolor gels for everything.
