This cake makes me so happy! I’d love it at Easter. And St. Patrick’s Day of course for those who observe? 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 the gel food coloring, 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 most normal people, I only have two round cake pans so I do the layers in batches. Be sure to grease the pans generously!
