  • 10 ounces mini marshmallows 1 bag
  • 7 cups confectioners sugar 6 cups and 1 cup divaded
  • 3 tbsp water
  • food coloring optional


  • Add the marshmallows into a microwave-proof mixing bowl.
  • Pour the water over the top and mix together to coat the marshmallows.
  • Microwave for 1 minute.
  • Using a silicone spatula, stir the mixture until it’s fully melted. 
  • Add in 6 cups powdered sugar two cups at a time and continue stirring. 
  • This is the messy part that takes a little more time. Just keep mixing and mixing! 
  • Continue to stir until it starts to form a ball. 
  • Once it forms a ball, remove it and place it on a clean surface or cutting board. 
  • Use the reserved powdered sugar to sprinkle sugar all over the fondant, even on your hands. 
  • Continue kneading the fondant with your hands, adding more sugar until it’s not sticky anymore.
  • You can also add a little sunflower oil on your hands to knead as well. This helps it not stick to your hands. 
  • Continue kneading with extra sugar if needed until the fondant is like a playdough texture. Not dry, but not super sticky.
  • If you want to create beautiful colors, divide the marshmallow fondant into smaller balls. Make a little round bowl in the center of the fondant and add in a few drops of food coloring. 
  • Fold the sides into the hole and then start kneading it together with your hands until the color is mixed throughout.
  • Either wrap the fondant and keep it stored or roll it out to cover a cake!


Save 1 cup of the sugar to sprinkle over the fondant when kneading. 
If the fondant is sticky it needs more confectioners sugar.
