You don’t need to serve this cake with anything (like icing, buttercream, ganache, fondant) because it is good as is and is too pretty to be “hidden” 😉 – Well unless you would want to make a “hidden surprise” cake though 🙂
Since there is a rainbow themed contest on instructables.com, I will be sending in this recipe 😀

400 ml egg whites
175 g sugar
175 g flour
25 g cornstarch
200 g margarine/butter, melted and cooled at room temperature
1 tsp cake emulsifier (without works too, but with cake would be fluffier and lighter)
food colors – liquid or gel
Parchment paper to cover a 9 inch round pan (you can make two cakes if you’d like – should you want to cover the cake with buttercream etc)

NOTE: if your emulsifier is powder, mix it with flour. If using paste-like emulsifier, beat it along egg whites
Enjoy 🙂
