I'm totally digging these multi-coloured cakes right now. Definitely see something like this working its way into my kitchen soon--and belly, for that matter. Om nom nom.
To my delight, I stumbled across the blog, i am baker, from which I gathered four of the six above snapshots. The site is run as a blog, but guests can also order cakes, cookies, and other sweet treats, along with find recipes--I highly recommend you visit. Some of these cakes will knock your socks off.
