    32 min

    Using plain marshmallows, it takes just three ingredients to make a lovely fondant icing that works well on all of your cakes. You can add a little flavouring, such as vanilla extract, in place of some of the water.

    Serves: 15 

    • 450g plain marshmallows
    • 900g icing sugar
    • 1 1/2 tablespoons water
    • butter or margarine, for greasing

    Prep:30min  ›  Cook:2min  ›  Ready in:32min 

    1. Place the marshmallows in a microwave safe bowl and set microwave on high setting for 30 seconds. Add 1 1/2 tablespoons of water. Grease a large spoon with butter or margarine, stir the marshmallows and keep melting in 30 second intervals until marshmallows are smooth.
    2. Begin adding icing sugar about 250g at a time, stirring between each addition, until the whole 900g is incorporated.
    3. At this stage the mixture gets sticky, so grease your hands with butter or margarine and knead on a greased work surface until smooth and no longer sticky.
    4. You can then grease your work surface lightly and roll the fondant out and place over cake that has been covered with marzipan or buttercream.


    You can add food colouring to create coloured fondant. Always remember to wear gloves to keep the colour off of your skin. This recipe is enough for two 23cm cakes.

    not to difficult turned out quite well, will be using again.  -  17 Sep 2012


    Great recipe! Turned out really well. i made it a couple of days in advance, all it needed was 15 seconds in the micro and was easy to roll. only suggestion i have is when colouring your icing invest in gel colourings rather than the cheaper liquid colours as this changes the texture slightly.  -  03 Oct 2013
