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 :)
