First Attempt at Rainbow Cake

I decided to try baking a rainbow cake for hubby's birthday. The idea came from some photos I saw in Facebook, so I looked up YouTube for the proper way to make it.

I used a normal butter cake recipe as my sponge cakes usually don't turn out too well. Bless my Science teacher in school for drilling into our brains the correct order of the colours of the rainbow - this is how I remember it:

Roy G. Biv...just pretend it's some guy's name, and there we have...

Red, Orange, Yellow, Green, Blue, Indigo, Violet!

Prepare the cake batter and pour into 7 paper cups,
each cup with the same amount of batter.
Add colouring.

Pour the first colour (I couldn't get it to turn red
no matter how much red colouring I used,
so pink was the next best option)
into a cake tin lined with non-stick baking sheet. There's nothing worse than
a beautiful cake stuck in the pan after baking!

Pour the next colour in the middle of the first colour.
Lift the pan about 5cm from the table
and let it drop so that the colour will spread evenly.

Repeat with the rest of the colours.
Bake.

This is how it looked like when taken out
of the oven.

I realised that I should have added a smaller amount
of batter for the last colour to get a more balanced layer.

There were lots of 'ooh' and 'aah' when the cake was cut and lots of photos snapped before the cake got eaten :)

This was a simple and quick way to make a rainbow cake. Next time I'll try the more time-consuming one...baking one layer at a time and assembling it (gasp):
