You need three times the following recipe:
- 125 g soft butter
- 225 g plain flour
- 150 g sugar
- 3 eggs
- 1 teaspoon of baking powder
- 1 pinch of salt
- 1 teaspoon of vanilla extract
- lots of food colouring: red, orange, yellow, green, blue and purple.
- buttercream ( an enormous amount!)
-2 greased and lined round tins
Preheat the oven to 180 degrees. Mix all the ingredients in a food processor and mix well. Divide the mixture in two and mix each with one of the colours (red and yellow). Put the mixture into the tins and bake for 12 minutes. Repeat this with two more colours (green and blue). And again with the two remaining colours (orange and purple)
Some recipes call for cream cheese icing but we put the cakes together with normal buttercream:150 gr butter, 300 gr icing sugar and 2 tablespoons of milk.
