Add vanilla essence to egg whites and whisk it again. 6. Add 2 egg yolks to egg white mixture and whisk it well. (We are using only egg whites as it will absorb icing colors to look bright). 7. Now add half of flour mixture to the butter mixture and whisk it well. Then add the egg mixture to the butter mixture and mix it well. 8.

Now take 6 different bowls to mix colors. In each bowl add 2 tbsp of milk. 11. Take a very small amount of icing colors and mix in the each bowl of milk one by one. Starting with purple icing color in 1 bowl, add all other colors to each bowl. Add just 1 drop of icing colors and mix it well. Do not use more icing color at once. If its less then add little by little. 12. Once mixing of icing colors is done in all 6 bowls with milk, add equal amount of cake batter to each bowl. Batter will be thick that's why we will add milk later to the batter after diluting the color in milk. Measure the batter with ladle and add equal amount of batter to each bowl and mix it well to get all rainbow colors. 13. If any color is less , now you can add little more color to the batter. 14.
