Had to try out rainbow cupcakes once I saw them on Spearmint Baby. A wonderful co-worker was celebrating a special birthday, and what girl doesn’t like rainbows? Or cupcakes? Exactly. So I commenced.
It certainly helped that I had access to some of the most potent food coloring ever to exist on earth. (Williams-Sonoma? Pottery Barn? I wish I knew.) But that batter above only has a SINGLE DROP of coloring in it. I wish I was exaggerating, it was just the best dye I’ve ever witnessed.
The cakes themselves were easy to assemble because, well, they’re just cupcakes. It was a little more labor intensive to smooth out the layers of color, but wowee, was it worth it. They emerged from the oven (perfectly) looking like a stormy doppler pattern, little works of art.
And we frosted. And taste-tested. Had to make sure we weren’t going to poison the whole office. Good to go. Very good.
