Easy Marshmallow Fondant

Marshmallow Fondant x200

It is really easy to make your own fondant and marshmallow fondant is amazing! It’s cheaper than the shop bought stuff and tastes so much better!

Ingredients :

  • 450g (1lb) marshmallows
  • 900g (2lb) icing (confectioners) sugar
  • 1 1/2 tbsp cooled boiled water
  • 1 tsp vanilla extract (optional)

Method :

  1. Put the marshmallows into a microwaveable bowl and heat on high for 30 seconds.
  2. Add the cooled boiled water and the optional vanilla extract.
  3. Grease a large spoon with Trex (white vegetable fat) and stir.
  4. Continue to heat at 30 second intervals until the marshmallows have melted and are smooth.
  5. Slowly add the icing sugar in parts, stirring after each addition until combined.
  6. Grease hands and work surface. Turn out and knead until smooth and no longer sticky.
  7. Wrap tightly in clingfilm and leave to firm up, preferably overnight.

Try it! You’ll be surprised how easy it is to make!

Storing :

Homemade marshmallow fondant will keep for a month or so if stored correctly. Always wrap your fondant tightly in clingfilm and keep in an airtight container – a clean, odour free lunch box is perfect. Fondant should never be refrigerated or frozen.

Recovering:

If your fondant is too soft, knead with some sifted icing (confectioners) sugar.

If your fondant is hard and crumbly, microwave it for a few seconds until softened. Do not add more water or you’ll end up with a sticky, sloppy mess. Remember to remove the clingfilm before popping it in the microwave!

    Hey
    Just wondering how much food colouring should be used to make the fondant a bright colour.

    • CakeBaker says:

      Always use a food colouring paste or gel – add tiny amounts until you reach the desired colour.

    Woah! I’m really loving the template/theme of this site.
    It’s simple, yet effective. A lot of times it’s difficult to get
    that “perfect balance” between superb usability and visual appearance.
    I must say you have done a excellent job with this.

    Additionally, the blog loads very quick for
    me on Chrome. Superb Blog!

    Hi! I stay in South Africa. We don’t get this Trex – white vegetable fat thing here. Any idea of substitute oil or something else that we could use to make the marshmallow fondant? We don’t get shortening here too. Thanks :)

    Hi there,

    In place of the 1 teaspoon of vanilla, would I be able to flavour it with other flavours, such as chocolate (with an essence)? If so, would I flavour it with the same amount? I am making a 3D reindeer cake for Christmas and my family does not like sugar paste, hence the questions..

    Kind regards

    Mamie

  16. RedRains says:

    How much would i need to cover a 12 inch cake

  17. carly says:

    Hi, can you use this fondant on a red velvet cake with cream cheese frosting? I’m asking as I made one with the normal shop bought fondant and after a few hours it seemed to almost melt off the cake. I’m assuming that this was due to the cream cheese as it’s never happened before on my usual buttercreamed cakes. Cheers
