Last week at playgroup we had "Rainbow Day", where the children all wore their favourite colour, we made a rainbow craft, and ate coloured food. I thought I'd make a marble cake, then decided to go one better and make a rainbow cake. I've never made a marble cake before, let alone a rainbow, but I'm all for experimenting!
It was a great opportunity to teach Miss 2 about primary and secondary colours: she helped mix the food colouring into the cake batter. It was so exciting for her, and so much fun for me to watch her discover the colours as they mixed.
I made a gluten free wacky cake batter, then divided it into six bowls, approximately 1/2 cup in each. We just added six or so drops of food colouring into each bowl. Then poured each colour in, one on top of the other starting with red, in rainbow order. Each successive colour displaces the one before.
We iced the cake with white butter cream icing to represent a cloud.
I actually made two cakes: one for home and one for playgroup. Miss 7 thought the cake was the tastiest one I'd ever made [it's the same recipe I've been using for cakes for a couple of years now]. Miss 5 only ate the cake, and left her icing on her plate as she didn't like it [usually she is like all children and only eats the icing]. It just goes to show you that food colouring makes all the difference to children!!
