The Omnomicon has a fabulous step-by-step Rainbow Cake tutorial and the colourful pictures alone are positively drool-dropping!

Fun for a colour party, a 60′s theme party, an art-lover’s birthday, or anytime you feel like brightening up the dessert table a bit.

You could also take the same concept and apply it to just a few colours or a different type of palette - maybe various shades of orange and yellow for a summer party, black and white or black and orange stripes, or the birthday person’s favourite colours, whatever they may be…

This next pic is one of my favourites… artistic, colourful, & all around lick-the-bowl delicious:

The baked cake looks so great it almost seems like it would be hard to cover it with frosting, don’t you think?! The pretty colours come through again when the cake is cut and served though!
