The Omnomicon has a fabulous step-by-step Rainbow Cake tutorial and the colorful pictures alone are positively drool-worthy! This recipe would be so much fun for a color 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 colors or a different type of palette - maybe various shades of green for St. Patrick’s day, red/white/blue for 4th of July, or the birthday girl’s favorite colors, whatever they may be…
This next pic is one of my favorites… artistic, colorful, & all around 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 colors come through again when the cake is cut and served though (see top pic, above).
For complete details, check out the full tutorial. Happy Baking!

Aleta –
Thank YOU so much for creating such a great tutorial to share! Your pictures turned out awesome!
Jenn :)
This is color lover’s dream dessert! Not sure I have the patience to make it, but just looking at it is very gratifying!
The BEST dessert I’ve seen in a long time. I can’t wait to make it!!
Coolest cake ever!!! Love it!
LOVE it!
All that food coloring doesn’t change the texture or the taste does it?
Great idea! I’m going to surprise my husband with a purple and yellow cake during a Lakers game next week
Gorgeous photos!!!

I don’t think the food coloring should make much of a difference in the taste/texture, but Aleta would be a good person to ask. I haven’t made this yet myself, but a couple people have mentioned to me that they’ve had this exact cake before and both said it was “delicious” and got rave reviews :)
Heather – fantastic idea about the purple/yellow Lakers cake! I have a friend whose husband is completely obsessed with the Lakers…I’m going to pass your idea along to her too :)
This is the best idea. My son will LOVE this bright colored cake. What a great idea!
i feel so cool right now just cuz i KNOW how to do it…
hmmm
i wonder if we have flour…
this cake is gorgeous! I was thinking of doing something like this for a theme party. I bet it tastes delicious :]
That looks so yummy, I wish I could have a piece of it right now! Just when I thought nothing was better than homemade cake, I see this and realized a pretty COLORFUL homemade cake tops it all! Thanks for the tutorial…I’m not too much of a baker, but this looks like it’s definitely worth trying!
Cool recipe!!!!!! :D I’ll definitely bake that cake!
Very cool cake…can’t wait to make it for my little girls party!! The other moms will be so jealous!!
