RAINBOW CAKE

February 18, 2019

This cake makes me so happy! I’d love it at Easter. And St. Patrick’s Day of course. Birthdays. And just normal life. Rainbows are beautiful and children love them. Sifting the flour and using just egg whites makes such a difference.

And this is like, THE DEFINITION of a thing to bake with children. Doing different layers is sweet and fun, and an art and color mixing lesson is included too.

A little tip, gel food coloring is much easier to mix in than drops. In general with it, a little goes a long way. Seriously for the purple I did just like a DOT of red and blue. But again, that is if you’re using gel coloring. And for orange, you want more yellow than red. Also like probably most normal people, I only have two round cake pans so I do the layers in batches. Be sure to grease the pans generously!

    I actually made something very similar for my grand daughter’s birthday several years ago. I wrapped all of her gifts in rainbow tissue paper and everything was all done in those colors. It really was pretty just like yours! Have a great rest of the week.

    Rachel,
    Do you think this cake would be a more vivid rich hue if I used more gel colour? I like your sample photo for Easter pastel but want it very deeply coloured for a happyrainbow party?
    Thanks for this!

    • Rachel Schultz

      YES! I just used as little as possible so it would look pastel, but they can be bright primaries by adding a few more drops : )
