  • 8 eggwhites
  • 4 cups caster sugar
  • 1 teaspoon vanilla extract
  • Blue, green, yellow, orange, pink and red food colourings
  • 1/2 teaspoon 100s and 1000s

Spread 1 portion into 1 prepared cake pan. Repeat with remaining 2 portions and prepared pans. Smooth surfaces. Bake for 25 minutes, rotating halfway during cooking, or until cooked through. Stand cakes in pans for 5 minutes. Turn out onto wire racks to cool completely. Wash and dry cake pans. Grease and line with baking paper. Repeat with remaining cake mix and food colourings.
