  • With the help of a whisk attachment, turn the mixer to a low speed and slowly pour into the sugar mixture. Once added, continue to whisk for a minute. Increase the speed to high for about 10 minutes or until it becomes a fluffy, white, marshmallow mixture.
  • Add the cotton candy flavour into it and whisk for a few minutes. Divide the mixture of marshmallows in two separate bowls. Colour each of the divided mixture with pink and blue.
  • Dust a 9×13-inch pan with the powdered sugar or flour to prevent the marshmallows from sticking. Pour the coloured marshmallow mixture into the pan one by one with alternating colours. Smooth the top with the help of spatula. Dust the remaining powdered sugar. Cover with plastic wrap and let it set for about 8-12 hours.
