Make soft, fluffy homemade marshmallows from scratch. This simple recipe yields cloud-like texture treats perfect for hot cocoa or s’mores.

Ingredients

Scale
  • 1 cup cold water, divided
  • 1 cup granulated sugar
  • 1 cup light corn syrup (or substitute with 3/4 cup honey or maple syrup for no corn syrup option)
  • 1 packet unflavored gelatin (about 2 1/4 teaspoons)
  • 1 teaspoon pure vanilla extract
  • Confectioners’ sugar and cornstarch mixture, for dusting

Instructions

  1. Lightly grease an 8×8 inch baking pan. Dust the bottom and sides generously with the confectioners’ sugar and cornstarch mixture. Set aside.
  2. In a small bowl, sprinkle the gelatin over 1/4 cup of the cold water. Let it bloom for 5 to 10 minutes.
  3. In a medium saucepan, combine the remaining 3/4 cup of cold water, granulated sugar, and corn syrup (or substitute). Heat over medium heat, stirring until the sugar dissolves. Stop stirring once it boils.
  4. Attach a candy thermometer to the pan. Cook the syrup without stirring until it reaches 240 degrees Fahrenheit (soft-ball stage). Remove from heat immediately.
  5. Pour the bloomed gelatin into the bowl of a stand mixer fitted with the whisk attachment. Beat on low speed until the gelatin softens slightly.
  6. With the mixer running on low, slowly stream the hot syrup down the side of the bowl into the gelatin mixture. Be careful not to pour it onto the whisk.
  7. Increase the mixer speed to high. Beat for 12 to 15 minutes until the mixture is very thick, glossy, white, and holds stiff peaks. This whipping creates the cloud-like texture.
  8. Beat in the vanilla extract during the last minute of mixing.
  9. Quickly scrape the marshmallow fluff into your prepared pan. Use a lightly oiled spatula to spread it evenly.
  10. Dust the top surface generously with more of the sugar/cornstarch mixture.
  11. Let the marshmallows set uncovered at room temperature for at least 4 hours, or preferably overnight, until firm.
  12. Once set, turn the pan out onto a surface dusted with the sugar mixture. Use a sharp, oiled knife or pizza cutter to cut the slab into squares. Toss the cut sides in the remaining dusting mixture to prevent sticking.

Notes

  • For clean cuts, lightly oil your knife before slicing the set marshmallow slab.
  • If you want gourmet marshmallow recipes, try adding 1/2 teaspoon of peppermint extract or a few drops of food coloring during the final minute of mixing.
  • These homemade vanilla sweets are excellent for gifting when cut into uniform pieces and stored in an airtight container.
