Onyx, I've made loads of zebra and rainbow cakes and you can use any type of cake you want, but they have to be the same consistency otherwise when you pour them into the pan, they wont spread properly and the layers/stripes wont look right. The way I do the rainbow zebra cakes is to make a couble quantity of batter, then split it evenly into however many colours I want to have - usually 6. Then I add the colouring to it and then alternatively pour it into the pan. Have you seen the FB pics I have of when I've done them? If you do cupcakes, you will literally only need a teaspoon of mix for each layer if you want a few layers/stripes, otherwise you can have less layers/stripes by using bigger spoonfuls of batter.
I was hoping you'd see this thread Trillian. I consider you the guru of rainbow cake.
Since I want Gryfinndor cupcakes I could use a vanilla cupcake mix and add red and yellow colouring? I wonder if my local cake supplies store has a dark red? I guess I could use my bright red with a drop of black?
Now I just need to figure out how to ice/top them....
LOL, thanks! Yep, basic packet buttercake is ideal - I use it all the time because the consistency is perfect. I wasn't sure if you'd use a packet one or make it from scratch. The colours you buy at the supermarket are no good - you need to buy some Wiltons Gel Colours - they are da bomb for getting vivid colours. The supermarket ones need a tonne of colouring added to get them as rich as you want them. I've used some pretty dark and light colours together and they don't relly run together that much, but you may want to use slightly more yellow batter so you have a thicker band of yellow between the red so you can tell that it's yellow kwim? Otherwise if you have a thin band of yellow it will be overwhelmed by the red. You've inspired me to make some up myself as a test for you LOL.
