  • 16 ounce package mini marshmallows
  • 2-5 Tablespoons water
  • 8 cups powdered sugar
  • 1/3 cup vegetable shortening


  • Place marshmallows and 2 tablespoons of water in a large microwave-safe bowl. 
  • Microwave for 30 seconds on high; stir until mixed well. Continue microwaving in 30 second intervals until they are melted and smooth.
  • Place about 5 cups of the powdered sugar on top of the melted marshmallow mixture and gently fold it into the marshmallows.
  • Grease your hands and your counter-top generously with shortening. Turn marshmallow mixture onto counter and start kneading it like you would dough. 
  • Add more confectioners' sugar as needed and re-grease your hands the counter-top as needed.
  • If the marshmallow fondant is tearing easily, it is too dry; add water (about 1/2 tablespoon at a time) kneading until fondant forms a firm, smooth elastic ball that will stretch without tearing, about 8 minutes.
