Royal icing

  • Ices 15-30 biscuits
  • Easy

Whether you’re decorating a festive fruit cake or building gingerbread houses, royal icing provides an elegant finish – opt for a classic white icing or experiment with food colourings


Make a batch of royal icing, then use it to decorate a selection of Christmas bakes, such as our Christmas cake, Christmas biscuits and gingerbread biscuits.



  • egg whites 3
  • vanilla extract 1 tsp
  • icing sugar 450-500g
  • food colouring gels a mixture of colours, (optional)


  • Step 1

    Whisk together the egg whites and vanilla extract with an electric whisk until frothy. Sift over 300g of the icing sugar and whisk again until thickened and smooth.

  • Step 2

    Add the remaining icing sugar, sifting in a little at a time until you reach your desired level of thickness. If you’re using food colouring gels, divide the icing between bowls based on the number of colours. If you’re flooding biscuits, loosen with a few teaspoons of water first.
