Homemade Peppermint Marshmallows

  • Total Time: 8 hours 40 minutes
  • Yield: 50-60 1x


  • 2 1/2 tablespoons unflavored gelatin
  • 1/3 cup + 1 tablespoon powdered sugar, divided that way
  • 1/2 cup of cold water
  • 1 1/2 cups of white sugar
  • 1 cup of corn syrup
  • 1/4 teaspoon of salt
  • 1/2 cup of water
  • 1 teaspoon of peppermint extract
  • Optional: 10-12 drops of red food coloring


  1. In the bowl of a stand mixer preferably), add in the water and sprinkle the gelatin over it. Let that sit while you prepare the syrup.
  2. In a medium pan, heat up the white sugar, corn syrup, salt, and water over low heat, stirring constantly. Keep stirring until the sugar has completely dissolved.
  3. Heat the mixture up to a boil and cook for up to 30 minutes without stirring at all. You want the temperature to be around 240 degree which you can check with a meat or candy thermometer. I have a not so great stove and it takes things longer to cook. If you have a gas stove, it may only take your mixture 8-10 minutes to get to the right temperature.
  4. Remove from heat.
  5. While mixer is on low speed, pour the syrup into the bowl with the gelatin. Increase speed to high and let beat for 8-10 minutes straight. You might need to stop the beater every couple minutes to re-position the mixture if it all gets clumped up a lot. The mixture should triple in volume by the time it is done.
  6. Add extract and beat for about another minute.
  7. Grease a 11×17 pan with butter and dust with 1 tablespoon of the powdered sugar. pour mixture in the greased and dusted pan. Wetting your hands lightly, pat the top of the mixture down so its even and smooth.
  8. Drop the food coloring evenly around the top of the pan and run a knife through each drop to create a pattern or swirls. I was not very careful with this part and the end result still turned out nice.
  9. Let sit for at least 8 hours.
  10. On a cutting board dusted with powdered sugar, place the giant marshmallow sheet. To remove it from the pan (if it’s not cooperating), butter a knife and run it along the sides of the pan in between the pan and the sides of the marshmallow. this will loosen it so you can get it out easier.
  11. Keeping your knife buttered, use a large, sharp knife to cut the marshmallow into your desired size pieces.
  12. Generously roll each marshmallow in the remaining powdered sugar so that they’re fully coated.
  13. ENJOY!
