How to... make Unicorn Rainbow Cupcakes

Create pretty pastel unicorn cupcakes with this simple step-by-step guide from Bath Cake Company.

Brought to you by Bath Cake Company

You will need:

For the cupcakes:

  • 8 ready-made cupcakes

To decorate:

  • buttercream
  • 2 or 3 Sugarflair paste colours (we used pink and ice blue)
  • white modelling paste
  • pink modelling paste
  • gold lustre dust
  • rejuvenator spirit


  • piping bag and star nozzle
  • dresden tool
  • paintbrush
  1. Divide your buttercream into three bowls and colour two of the bowls using Sugarflair's paste colours, leaving one plain.
  2. We've chosen pink and ice blue for pretty, vibrant colours.
  3. Fill one piping bag with all three colours – try not to mix them so you can clearly see each colour.
  4. Pipe a buttercream swirl onto your cupcakes.
  5. Take some white modelling paste and knead it well so it's soft and easy to work with.
  6. Pull off a small amount and roll it into a ball.
  7. Roll your white modelling paste into a teardrop shape.
  8. Press down with your palm on the wider part to flatten slightly.
  9. Repeat with some pale pink modelling paste but starting with a slightly smaller ball, then press the pink teardrop onto the white ear.
  10. Make two of these, then add to the buttercream swirl.
  11. For the horn, start with a ball of white modelling paste and roll it into a long horn shape. Mark the horn in a swirl motion with a dresden tool.
  12. Mix some gold lustre dust with rejuvenator spirit and paint on the horn.
  13. Push the horn into the buttercream and your unicorn cupcake is complete!
