Marshmallow Icing recipe

Preparation Time: 5 minutes | Cooking Time: 10 minutes

This thick, sweet and creamy marshmallow icing is perfect for icing all sorts of cake creations. You can flavour the icing by adding a little flavoured extract, such as strawberry or orange extract, or you could add a little cocoa powder.


  • 300g caster sugar
  • 2 egg whites
  • 1/4 tsp. salt
  • 1/4 tsp. cream of tartar
  • 5 tbsp. water
  • 4 medium white marshmallows
  • 1 tsp. vanilla extract


  1. Place the sugar, egg whites, salt, cream of tartar and water into a bowl. Suspend the bowl over a pan of boiling water.

  2. With one hand, hold the bowl steady. With the other, beat the ingredients using an electric whisk or mixer for 7 minutes, or until the ingredients are completely combined. The icing should form firm peaks, like when you whip egg whites.

  3. Take the bowl off the heat and place onto a tea towel. Stir in the marshmallows and keep stirring until the marshmallows have melted into the icing. Leave to cool for a couple of minutes, then whisk in the vanilla. Use to ice the cupcakes.

This icing is easily coloured, too - just add a little food colouring paste when the icing is ready and beat until it has incorporated into the icing. Recipe ices 30 cupcakes.
