How to make rainbow cupcakes

You will need



  • No.10 star nozzle
  • Disposable piping bags
  • Dessert spoons
  • 3 bowls


1. Separate your cupcake batter equally into five bowls.

2. Use the five Colour Splash gels to colour each bowl. Colours can intensify during baking so we recommend using a smaller amount of gel for better results.

Top tip! Add colour gradually - you can always add more!

3. Starting with one colour, divide the mixture equally between the baking cups using a dessert spoon and smooth it out so you have a layer at the bottom. Continue with all the other colours in the same way, evenly spreading each layer out and being careful not to mix the colours together so that you end up with distinct layers of colour.
