I've been wanting to make one for a while so of course I said yes.
I ordered some AmeriColor oil based food dyes to use from Baking Pleasures. Whilst I will be using Betty Crocker Vanilla frosting for this cake these are meant to be great for using with buttercream too. I hate the buttercream splitting when using water based food colours.
I doubled my favourite cupcake recipe and split it into 6 bowls.
Tulip Red, Electric Orange, Lemon Yellow
Electric Green, Electric Blue, Regal Purple
I had to use a fair bit of the red and probably could have used a little more. The purple wasn't quite as vibrant once cooked either, but that's why I have done a test run :)
Rainbow cupcakes all lined up. I think the colours look fab!
The kids have loved them and by the looks they are eating them for lunch!
