Rubix Cube Cake

My boyfriend is obsessed with the Rubik's cube so I decided to make a Rubix cube cake for his 30th birthday.

What you will need:

  • 3 box cake mixes (mix it up for fun! I used red velvet, German chocolate, and white)
  • 9x9" square cake pan
  • Cake leveler (or a long knife)
  • 10-12 inch cake board
  • White frosting, enough to cover all 3 cakes (Tip: I used Wilton decorators frosting, as it does not thin when food color is added)
  • Icing/food coloring in red, yellow, blue, green, and orange (Tip: I used Wilton gel icing colors)
  • Black icing (this can be difficult to make using white icing and black dye, so I used a tube of Wilton black decorating icing)
  • 6 pastry bags
  • Any star tip (tips will also work on tube of black decorating icing)
  • Preparing the Cake:

    1. Bake all 3 cakes per the directions on the box and let cool completely.

    2. Once cooled, flip the cake onto a cooling rack or cookie sheet. Use another cookie sheet to flip the cake back to the right side up position.

    3. Now it is time to level the cake. Using your leveler or long knife level off just enough to make the top completely flat and square like. Be careful not to take too much off.

    4. Repeat steps 2 and 3 with the other 2 cakes.

    Assembling and Decorating the Cake:

    5. Take cake #1 and place it on the cake board.

    6. Frost the entire top of this cake. (I used regular store bought chocolate frosting.)

    7. Take your black icing tube (or black icing you dyed yourself) with your star tip and begin to pipe along the bottom perimeter of cake #1.

    8. Now pipe the black icing along the top perimeter of the Rubix cube cake.

    9. Pipe the black icing up the sides of all 4 corners.

    10. Pipe black icing in 2 vertical lines along the sides forming 3 equal squares on all 4 sides.

    11. Place cake #2 on top of cake #1 in a diagonal position so that the corners of the cake alternate.

    12. Frost the entire top of cake #2.

    13. Take your black icing tube (or black icing you dyed yourself) with your star tip and begin to pipe along the bottom perimeter of cake #2.

    14. Now pipe the black icing along the top perimeter of the cake #2, and up all 4 corners.

    15. Pipe black icing in 2 vertical lines along the sides forming 3 equal squares on all 4 sides of cake #2.

    16. The corners of cake #1 should be visible from under cake #2 and due to piping all perimeters of the cakes, should be lined in a triangle of black icing. Fill these corners in with black icing.

    17. Place cake #3 on top of cake #2 in a diagonal manner so that the corners alternate. (The corners of cake #3 should align with the corners of cake #1.)

    18. Do [Not] frost the top of cake #3!

    19. Take your black icing tube (or black icing you dyed yourself) with your star tip and begin to pipe along the bottom perimeter of cake #3.

    20. Now pipe the black icing along the top perimeter of the cake #3, and up all 4 corners.

    21. Pipe black icing in 2 vertical lines along the sides forming 3 equal squares on all 4 sides of cake #3.

    22. Pipe the black icing on the [top] of cake #3 forming 9 equal squares (2 lines vertical and 2 lines horizontal). Tip: these lines should match up to the vertical lines along the side for a more realistic look.

    23. The corners of cake #2 should be visible from under cake #3 and due to piping all perimeters of the cakes, should be lined in a triangle of black icing. Fill these corners in with black icing.

    Filling in the Color Squares: (It helps to have a real Rubik's cube on hand for this part.)

    24. Dye your icing one color at a time and place into a pastry bag.

    25. Using your filled pastry bag and star tip start to fill in your squares on the Rubix cube cake, both the sides and the top. Mix up the colors for a more realistic look (again, refer to an actual cube for assistance.)

    That's it! It is surprisingly easy and looks great! Good Luck!

    Rubiks Cube Cake

    My sister was celebrating her 40th Birthday, and wanted an 80's themed cake. I decided to try my hand at a Rubix cube cake. It turned out so cute I just had to share it!

    Ingredients:

    • One 8x8x2" square cake pan (use 3 pans, if you have that many - it would sure speed things up)
    • 1 small bag of black licorice (cut lengthwise)
    • 3 store-bought (or homemade) cake mixes (I used 3 different flavors: Funfetti, chocolate, and classic white)
    • Store-bought white frosting
    • 1 pkg. food coloring (you will need red, yellow, blue, green, orange)
    • 10" square cake board
    • Two 8x8 square cake boards (trimmed to make it a tad bit smaller, covered in foil)
    • Dowels
    • Any size star tip and pastry bag
    • Cake leveler or long knife

    Preparing Cake:

    Prepare cake as directed on the box in 8x8" pan. Check with a toothpick to see if it's done. My cake took about 10 minutes longer because of its thickness.

    Let cool for about 5 minutes, and remove by placing it in the center of a 10" cake board. Allow cake #1 to cool completely.

    When cake #2 is finished, remove it from the pan by placing foiled cake board (over the pan) and flipping the cake onto it. Then flip the cake onto the other cake board so the top of the cake is now top side up.

    Trim off top of the cake so it's level (careful not to trim off too much). Allow it to cool completely.

    Repeat with cake #3. Once all the cakes have cooled, you are ready to assemble.

    Putting It All Together:

    First frost top of cake #1 (the one on the 10" board).

    Place dowels: one in the center and one at each corner (not all the way in the corner - just about where the next cake board will be going). Dowels should not be taller then the height of the cake.

    Now place cake #2 on top of cake #1. Frost and place dowels (same as cake #1). Now place cake #3 on top.

    Decorating the Rubix Cube Cake:

    Place white frosting in pastry bag, and pipe along the bottom of the cake to fill in all the gaps. Then pipe in frosting between cakes #1 and #2, and the same for cakes #2 and #3.

    Now pipe frosting going up each edge, and on top and on sides to make 9 equal squares. Place licorice on the frosted edges (cutting some to length and others keeping full length) to make your squares stand out.

    The frosting should hold the licorice in place. It did for me, and I've made this cake twice already.

    Now it's time to color the cake.

    Mix colors into the frosting making red, yellow, blue, green, orange and white. Start with one color and fill in areas with your star tip.

    Mix colors up a bit to make it look realistic. (It helps if you have a real cube on hand to look at.) After filling in all squares - you are done!
