Introduction: Making a Companion Cube Cake. 
	Thought about making a Companion Cube cake? Well, here is how I made my cube cake! It takes a bit of time (12 hours or so) but is worth it!
	This instructable is brought to you by "Pandora's Box Bakery" located in Seattle, WA. Step 1: What You Need. - A reference picture or two of the Companion Cube
- Food colors (black and pink)
- Multiple bowls and spoons
- Your favorite recipes for cake or a box mix if you must
- Disposable piping bags
- Arteco tips #801 and #803
- The bowl scrapper and smoothing tool from Arteco (see the second to last step if you are unsure what these are)
- An 8 by 8 square baking pan

- A slightly damp washcloth to clean your tools when icing
- Plastic wrap
- A freezer with plenty of room for the entire cake

- A playlist for the 12 hours you will spend on this cake.  Step 2: A Quick Note. This tutorial is how I make my Companion Cube cake. I use frosting because I am not a fan of fondant (does not taste that good). All of my recipes I used for the cakes are not shared for the sole reason of keeping my "secrets" secret! Hope you enjoy this Instructable! Step 3: Onto the Cake Making!. 1. Alright, now that you are dedicated to making this cake, take a deep breath and let's do this!
2. Make your batter and pour it into a greased pan and bake for however long it says in the desired temperature.
3. Once that is done, cool in the pan and prepare your next batter while it is cooling.
4. Once the pan can be somewhat touched, put in the freezer to cool it faster. This saves some time!
5. Once out of the freezer, flip it out onto the two pieces of cardboard that are together with the foil or whatever you decided to use. (If it is your other cakes rather than the first one, flip it out onto the extra cardboard piece and CAREFULLY place it on top of the other cake that has the filling on it.)
6. Like any cake, if you do not have a true oven, cut the top so its even!
7. Repeat steps 1-6 five more times! (Yes! It is a six layer cake) Step 4: Now Onto the Icing!!. 1. Prepare your icing. Go to the last step for my icing if you want to prepare it like I did. I doubled the recipe to get enough icing for the cake.
2. Split the icing and put half of it in another bowl. One bowl you want to dye grey. Dye it by using "Spectrum" company "Super-Black Gel Color" product, use two drops. The other bowl will harbor the white icing.
3. Prepare your icing bag. Put the #803 tip in the bag and cut a half inch above where the tip stops. Put some of the white icing in the bag and be careful not to overfill the bag. Push all the icing down to the bottom of the bag with the bowl scrapper from Arteco. Now you are ready to ice the cake. Step 5: The White Frosting Icing!!!. 1. Take a look at my picture... Use your white icing and start making the boxes and circles on each side of the cake. Make sure there is enough icing on the cake to spread nicely and not thinly.
Note: Do not smooth it out just yet, you have another step before that one! Step 6: The Grey Icing!!!!. 1. With another piping bag and the other tip, do the same thing to prepare it and this time, add your grey icing into it.
2. Now, go around all the white icing and start filling in with the grey! See the cube starting to form? Step 7: Smoothing Out the Icing!!!!!. 1. Self explanitory really. You get to smooth out the icing. Start with the side you first iced since the icing got to set a bit longer than the other sides. Then move on to the second side you iced, then the thrid, you get the picture.  Step 8: Finishing the Cake. 1. Chill the cake for an hour or two to freeze up the icing.
2. Once it is done chilling, the frosting will be nice and pliable but can still come off, so be cautious!
3. Time to smooth out peaks that may have occured. Do this with your fingers. After you touch the frosting, wipe your hand off on a clean towel. Do this until the icing is smooth.
4. And presto! You are done! Congratulations! You have successfully made a Companion Cube cake! Step 9: The Tools.... The white tool is the bowl scrapper, an amazing tool to have really. If you do not have it, not a big deal, can still do this without that.
The black handled one is the smoothing tool, you will need this. A smaller size is better since there are many colors. Step 10: The Icing Recipe. Alright, so the recipe for icing that I used is pretty easy. I made double the recipe, so I will give you that one instead of you having to double it yourself. (Just saving you one step)
Ingredients:
2 pounds powdered sugar
2 cups shortening (I like to use Crisco)
1/4 cup of water
1 teaspoon vanilla extract
Food coloring if desired
Directions:
1. Add the first two ingredients together, use a large bowl to avoid the powdered sugar from coating you instead of the pan. Start to mix (I handmix this but you can use a mixer).
2. Once that is getting harder to mix and clumps are everywhere, add a bit of the water slowly and in little batches. Remember, you cannot take out any water once you put it in! Now, mix the frosting, it should start becoming softer and more pliable. If not, add a little bit more water.
3. Once that is done and you have the right consistancy, (should be able to pass the "spoon test" which is scooping some frosting up and hanging it upside down, should not budge) divide the frosting into thirds. But two of the frosting thirds into seperate bowls. Dye one grey and one pink and keep one white.
