Pour each of the mixture, side by side in baking pans (3, 9" round cake pans which have been buttered and floured). Use a spatula to blend the colours, but do not mix too much. Move the spatula in a circular motion throughout.
Bake in a preheated oven 180 degrees for 20 minutes. Cool for 10 minutes then transfer to cooling rack.
