RAINBOW cake it up!

So, I've had the great opportunity of making this crazy yet awesome cake 5 times now in the
past 3 months. It's called Rainbow Cake for the simple reason of being a 6 layered cake with
colors of the rainbow. I'm not too much of a baker but there are a few cakes I really enjoy
to make but more importantly...EAT!
Flourless Decaf Espresso Chocolate Cake being one and the second new favorite is the Pumpple.

Making this cake takes a teeny bit longer than the normal cake but it's SO worth it. After your white/vanilla cake batter is ready... (2 boxes) you want to split your batter into 6 even amounts.

Here is one, and then here are 4.... (you want a total of 6)

Then you add drops of food coloring for each color of the rainbow.  (ROYGBIV)
You want to start with the bottom layer first. Purple being the bottom layer of the cake.

For some reason- purple always looks grayish before it is baked.
Then you want to follow with the blue- followed by green, yellow, orange and then- lastly, red.

Then you take your cake pan (the pans with the sides that get unleashed work best)

I cook 2 at a time- simply because I own 2 pans.
If you have more than 2 pans- try it all at once... be a rebel!
Once each layer is baked (you can stick a toothpick in the center and see if it comes out clean)
I take the sides of the pan out and throw each layer in the refrigerator.
As I start the 2nd batch of the next 2 colors- and clear the counter area a little bit-
it's already time to take the first ones out from the refrigerator.
(as they are chilled it becomes way more convenient to take off the bottom of the pan.
I start with carefully centering the purple layer on the middle of the plate.
Then I add a little icing followed by the blue layer, than more icing etc... for all 6 layers.

It's always a "wow", "oooo" "let me take a pic" moment when you cut into this cake!
I think I might try to alternate red and green for the next one....
