Create a beautiful watercolour effect with icing to decorate a cake that is perfect for any occasion.
30 minutes

You will need

  • food colouring of your choice
  • turntable (or use a cake stand)
  • small off-set spatula
  • large scraper or spatula



  • 2 piping bags (optional)
  • sprinkles, a cake topper or candles, to decorate


Divide and colour the icing. Keep the largest portion white as it will need to cover the entire cake.

Cut off the tops of the cakes so they are level. Place one cake in the centre of the turntable, if you are using one, or on a cake stand. Spread about 125ml icing evenly over the top, staying just inside the edge of the cake. Place the second cake on top and press down lightly.

Brush off any crumbs and coat the cake with a thin layer of white icing, called a crumb coat. Next, cover the cake with a generous layer of white icing. It doesn’t have to be perfectly smooth, but try to get an even layer around the cake.

Spoon the coloured icing into piping bags and snip off the tips. Pipe blobs of icing of each colour onto the side of the cake. If you don’t have piping bags, you can use the small spatula to smear on the blobs. Varying the sizes of the blobs and how close they are to each other will create different effects.

Hold the scraper or large spatula straight up against the cake and slowly rotate the turntable or cake stand while scraping the icing. Do a section then clean the icing from the scraper before continuing. For more colour, pipe more icing around the sides and repeat. Once most of the excess is off , scrape again in one smooth motion, just touching the surface. The more you scrape, the more the colours blend.

Pipe icing blobs in a circle on the top of the cake. Start scraping with a circular motion using the small spatula. Neaten the edges where necessary. Transfer the cake to a cake stand if you used a turntable. Decorate with sprinkles, a cake topper or candles.
