  • 350 gm Refined Flour

  • 10 ml Vanilla Essence
  • Gel Colours - Red, Orange, Yellow, Green, Blue, Violet


  • 200 gm Butter
  • 300 gm Icing Sugar
  • 100 ml Milk



  • Beat butter and sugar using an electric whisk until its creamy.
  • Add eggs one by one and keep whisking, at this stage you might feel that your batter is getting too wet but keep whisking till it achieves creamy texture.
  • Add vanilla essence.
  • Sieve in flour and baking powder into the wet mixture and mix using cut and fold method.
  • Preheat oven at 180 degree Celsius.
  • Divide batter into six equal portions, add food colors.
  • Grease 6 inch cake tins, transfer the batter, give it a tap on the floor and place it in the oven for 20-25 minutes.
  • Check with skewer if the cakes are cooked from inside. Once they are out of oven, let them cool down for an hour or you can make your sponges one day prior.


  • Using an electric whisk, cream butter.
  • Add in sugar gradually while whisking the butter.
  • Whisk butter and sugar at high power till it reaches stiff peaks consistency.
  • Add milk and start beating again for about 5 minutes, you will see a smooth and glossy cream and that’s your silky smooth buttercream frosting.


  • Put some cream on the base and place violet sponge.
  • Apply sugar syrup on the sponge, this is an optional stage. I don’t like to soak my cake with sugar syrup so I skipped this stage.
  • Apply buttercream and repeat this process by following the VIBGYOR pattern.
  • Cover the cake with buttercream and keep it in refrigerator for half an hour.
  • Once it’s set, apply more buttercream and give it finishing touches by dipping palette knife in warm water. This will give a smooth texture to the cake.
  • You can make floral designs using nozzles and sprinkle some rainbow sprinklers.
    Rainbow cake is ready!!
