Rainbow Cake

This week I finally had an excuse to make a cake. I've been foaming at the mouth to try making a rainbow cake as I've seen posted so many times on the interwebs (just Google "rainbow cake" and see!). I especially enjoyed this and based mine mostly on this.
Here we go:













I've never done a 'complicated' cake so this was both exciting and worrisome. I bought 2 boxes of cake mix because I didn't know if one would be enough as I wanted to divide the cake into 6 layers. I mixed just one box first to check and it looked like enough batter for my purpose. I prepared the batter following the box instructions.
The Wilton gel colors are very vibrant, it was fun shading the cake batter. The box mix created 4 cups and I divided it into 6 portions and colored each using 6 of the 8 gel colors provided (brown and pink were the other shades in the set).













I greased three 8-inch cake pans with shortening, dusted with all-purpose flour and poured in the red, yellow and orange batter. They baked for about 18 minutes at 325F and after cooling 15 minutes they were turned out and cooled on wire racks.

The pans were washed, dried, greased, floured and filled with green, blue, and violet batter.
While they were baking, I shifted the cooling cakes to plates and put them in the fridge.

After cooling the last 3 layers, they went in the fridge, too.
I was getting ready to ice the cake and they say getting the cake cold will keep it from being as crumbly and getting the icing funked up when you start working it.... seemed to be a success, not much crumbage.


Mmmmm, icing. This icing is really good. I ended up having to run out and buy a 2nd can of it, not because I ate a bunch! but one just wasn't enough to spread between 6 layers AND cover the whole outside. I kinda knew I'd need 2 but I didn't want to risk only using one and then having a tub of icing sitting in the cabinet haunting me, calling me.
I have a horrible icing-binge memory.... don't ask. *urp*


This is the 'dirty icing' step, to get everything mostly covered with the frosting then put the cake in the fridge to let the it harden and contain the crumbs. I'm a total novice with an icing spatula but did a fair enough job. I used the trick of putting 4 strips of wax paper between the bottom cake layer and the plate so when you're done frosting you just slip them out and the plate is clean. Super cool.

After it chilled for a couple hours, I frosted the cake with the rest of the 2nd can of icing, then removed the wax paper strips. I'm so ready to cut this thing! But had to wait several more hours *omg suspense*
It doesn't look too exciting hanging out in the fridge, just a plain homemade cake. But that's part of the surprise :-)
Another part of the surprise was that the blue candles also had blue flames - yahoooooo!

Finally the moment arrived..... time to cut the cake......



Wheeeeeeeee! It's perfect! Ok it's not *perfect* perfect, but it is a perfect surprise.
And it tastes really really good, too.



Somebody reported pooping a rainbow this morning but there were no witnesses to substantiate this claim.




All this thinking about cake...... I'm off to have another slice :-D
