A tried and tested Marshmallow Fondant recipe that’s easy to make at home! Use this sugary fondant to decorate all your favorite baking!



  • 8 cups mini marshmallows
  • Vegetable shortening
  • 1/4 cup water
  • 2 lbs powdered sugar


  1. Place your marshmallows into a microwave safe bowl. Add the water.
  2. Microwave on high for one minute and stir. Continue microwaving for 30 more seconds until the marshmallows are almost completely melted.
  3. Add half the bag of powdered sugar and stir until combined.
  4. Lightly grease your counter or work surface with shortening. Pour the remaining powdered sugar onto the greased area.
  5. Pour the marshmallow and sugar mixture over the pile of powdered sugar on the counter top.
  6. Coat your hand thoroughly with the shortening to prevent sticking. Knead the powdered sugar into the marshmallow mixture until it the texture is no longer sticky and you can form it into a ball.
  7. Lightly coat the fondant with a thin layer of shortening. Wrap the fondant in cling wrap (completely airtight) and let it rest for 30 minutes. Allow the fondant to cool completely before you use it.


If you aren’t going to be using it the same day, seal the wrapped marshmallow fondant in an airtight bag (squeezing out all the extra air) until you are ready to use it. Fondant is best used within 3 weeks of making.
