Awesomely Easy Rainbow Cake!

Today one of my friends shared a post featuring some perfectly adorable teeny tiny rainbow cakes. Which reminded me of this post about making Sprout's birthday cake, that I had forgotten all about and left languishing in draft for over 2 years! My rainbow cake was neither perfect nor teeny tiny, but it was bright!

This rainbow cake was made by layering batter ...  6 different colours of batter.

I divided one plain white batter into 6 bowls and added a whole lot of food colouring!  The batter layering method I used doesn't produce evenly striped layers, rather, each colour, poured into the center of the pan, pushes some of the last colour out a little, making sort of arched layers. I alternated the order of the colours for the 2nd layer of the cake, just because :)

Note the tube of cherry cola lip smacker on the counter - totally needed for all the lip licking I was doing in anticipation of tasting my delicious creation!

Once the cakes had baked & cooled, I flipped one upside down on to a foil-covered cake plate, spread a layer of white frosting on it's flat bottom-become-top, and placed the other cake right side up atop it:

Oops, some of the top of the cake stayed stuck to the plate I'd flipped it out of the pan on to - no worries, frosting would cover that ... and it turned out to be a good thing that happened anyways! (Read on to find out why.) 

The plan was to cover the whole cake in fluffy white frosting, so when we cut into it, the colourful rainbow cake would be a surprise - a rainbow in a cloud! But oops again, I hadn't made enough frosting:

That turned out not to matter though, because before I made more, Sailor Boy & I tasted the bit of cake that had stuck to the plate, and YUCK! It did not taste good at all, it tasted BAD! Something had gone off :(

It was a rainbow cake wreck.

So sad. All that cherry cola flavoured lip licking for naught :(

I sniffed both the oil and the food colouring and neither smelled very good to me, so who knows... And since we couldn't serve it to the sproutlets and party guests, there was no sense in continuing with the frosting - but before we tossed it, I did cut into it to see how the rainbow layers came out...

And ooooh, it looked awesome! 

Fortunately, since the party was not until the next day, I had time to get more ingredients and bake another cake. The 2nd attempt, made with a fresh bottle of oil and new gel food colouring, was delicious. I was in a hurry by then since it was late at night, so didn't bother with pics, but a small sample taken before it was frosted did taste good, and the birthday partiers loved it! It looked pretty much just like the inedible attempt anyways, so here's that pic again :)

Awesomely Easy Rainbow Cake:

1. Make up a batch of light coloured cake batter.
2. Evenly divide the batter into 6 (or 7) bowls.
3. Colour the batters red, orange, yellow, green, blue & purple (or indigo & violet if you do all 7). Liquid gels works best for vivid colours.
4. If you want your stripes to be in correct rainbow order, begin with the red batter. Pour all the batter into the center of a round cake pan.
5. Repeat with each colour in order, pouring directly on top of the the last colour, in the center of the pan. 
6. Bake as directed for your batter of choice, cool, invert, & frost!
