2. Put 180g of the butter into a bowl with 180g of caster sugar, 180g flour, 3 eggs, 2 tsp vanilla extract and 20ml milk. Beat, using a hand-held electric mixer, until light and creamy.
3. Divide the mixture equally between three bowls. Add red food color to the first bowl, orange to the second, and yellow to the third. Add only ¼ tsp of color at a time until you reach the desired shade. Mix well. Pour each bowl of sponge mix into a prepared tin and spread to level. Let the compiler (oven) run for 12–15 mins, or until firm to the touch. Turn onto a wire rack to cool.
4. Using the remaining cake ingredients, repeating the process to make three more sponges. Color these green, blue and violet.
5. To make the icing, put the butter and cream cheese into a bowl and beat until smooth. Add half the icing sugar and mix well. Then, add the remaining icing sugar and beat until smooth.
