This gave me the idea no unicorns involved
I used a basic madeira recipe because I felt a vicki sponge might be a bit delicate, and madeira is quite robust:
8oz/225g plain flour
1 tsp baking powder
8oz/225g butter or margarine, at room temperature (I?ve always used butter!)
8oz/225g caster sugar
1 tsp vanilla extract
4 eggs
Divvied the batter into seven, 200g,next one 180g, next one 160g etc. I used cereal bowls for the larger amounts and then those ikea plastic bowls as the volumes decreased. Colour each bowlful of batter with paste colour, then follow the technique for unicorn rainbow cake.
Bake until blade comes out clean (mine was I think 50 mins at 160 degrees)
Delicious
I covered my cake with ready roll icing, secured with quince paste [ponce] instead of apricot jam, then it looked a plain cake, til cut with a TA-DAH stylee flourish
