  1. 8 eggs
  2. 10 tbsp milk
  3. 2 tbsp vanilla extract
  4. 5 and a half cups of self raising flour
  5. 3 cups unsalted butter
  6. 3 and 1/4 cups caster sugar
  7. Buttercream (mixture of butter and icing sugar)
  8. Food colouring – the colours are your choice and it depends on how many layers you want to make
