Betty's Easy Steps

  1. Preheat the oven to 180°C (160°C fan forced). Line a 12-hole muffin pan with 12 paper muffin cases.
  2. Make the cake batter as directed on the box using the eggs, butter (or oil) and milk or water. Divide the batter evenly between the muffin cases.
  3. Bake for 20-24 minutes until risen, golden and just firm to the touch. Cool for 5 minutes, then transfer to a wire rack to cool completely.
  4. Mix the sachet of frosting (included with the cake mix) with the vanilla frosting in a bowl until smooth. Divide the frosting evenly between three bowls. Beat in a little blue, pink or yellow food colouring paste or gel into each bowl to colour the frosting.
  5. Spread the frostings over the top of the cupcakes with a small palette knife (4 cupcakes for each colour). Sprinkle each one with a few multicoloured cake sprinkles.
  6. Arch one rainbow sour strap over each cupcake, pressing gently into the frosting. Add 3 halved mini marshmallows at each side of the rainbow sour strap to resemble fluffy clouds.
  7. The unfrosted cupcakes will keep in an airtight container for 2-3 days.

Betty's Tips

  • Instead of the mini marshmallows, pipe or spoon a little vanilla frosting to resemble the clouds, if preferred.
