Ultimate Rubik’s Cube Cake

I really like to make cakes.

When my nerd best friend and some of his fellow engineer friends had birthdays close together a few years back, I decided I would make them the most awesome nerd cake.  What would be cooler than a Rubik’s cube cake? NOTHING.  (not literally nothing – nothing as in a Rubik’s cube would be the ultimate nerd/engineer cake)  So, I made a Rubik’s cube cake.  It was hard, since I decided to do squares of fondant, and then somehow meld it all together atop a frosted cube-shaped cake.   Well, after an untold number of hours I finished it!  Here are a few pictures:

The “making of” pictures are a little too graphic.  Luckily, despite all my handling, it tasted really good!  I hope they liked it and experienced it to the fullest, because I will never attempt this again.  I will post the fondant recipe and instructions here for anyone crazy as I am.

MARSHMALLOW FONDANT RECIPE

3 cups mini marshmallows

1 Tbs water

1 tsp vanilla

food coloring – various shades

6-8 cups powdered sugar

cornstarch

2 cups semi-sweet chocolate chips (for black lines)

Put marshmallows into glass bowl, drizzle with water and melt on 50% power for about 2 minutes, stopping to stir a couple times.  When nice and melted/fluffy/soupy, add vanilla and separate into 6 bowls.  Add coloring to each bowl except 1 for white.  Add about a cup of powdered sugar to each bowl, then take each and knead it atop cornstarch.  Use plenty as it can be sticky.  Roll it out and cut it into 6 squares or so with pizza cutter, using paper square as template, set each square aside atop cornstarch.  Put extra fondant into plastic baggie and set in fridge in case you need it later (haha you’ll find it again in a month and not know what to do with it).  Do this with each color until you have 45 squares. (hopefully you reserved your whole morning or afternoon)

Place 9 squares on each of 5 sides (no way you want to do the bottom of the cake) of freshly-frosted cube cake.  If they don’t stick, dab the backside with water before putting onto the cake.  After they are all placed, melt chocolate chips in a glass bowl (yes this requires a lot of bowls, it feels like 50) at 50% power for about 2 minutes, stopping a few times to stir.  Place half into a plastic bag with tiny bit of edge clipped/pastry bag with small round tip and pump chocolate in straight lines to separate colors of Rubik’s cube.   Have fun!  If/when  you use up the whole bag, move on to the next half of the melted chocolate. (if you used a plastic bag use a different one.)  Place cake in fridge/cold place for 20 min to firm up the chocolate and fondant.  Enjoy with all your nerdy friends!
