  • 3 - 1/4 ounce packages unflavored gelatin
  • 1 cup cool water divided
  • 1 1/2 cups granulated sugar
  • 1 cup light corn syrup
  • 1/4 teaspoon salt
  • 1 tablespoon vanilla
  • 1/2 cup powdered sugar divided


  • Coat a 9x13 baking pan with cooking spray. Set aside.
  • In a large bowl, mix the gelatin and 1/2 cup of the cool water. Let stand until soaked.
  • While soaking, in a medium saucepan, mix together the rest of the cool water, granulated sugar, light corn syrup and salt and heat on medium until sugar is completely dissolved, about 5 minutes. Turn heat up to high and bring to a rapid boil for one minutes, without stirring. Mixture will foam and rise quickly and then fall and continue to simmer. Remove from the heat.
  • Slowly pour the warm sugar mixture into the large bowl of gelatin while beating on low with a hand mixer. Increase speed to high and whip mixture until light and fluffy, about 10 minutes. Add vanilla and beat to combine.
  • Using a greased rubber spatula, pour the mixture into the greased pan and spread out evenly. Sprinkle with 1/4 cup powdered sugar and place in the refrigerator for 3 hours or overnight before cutting.
  • Use a greased cookie cutter or knife to create shapes of marshmallows you desire.
  • Place cut out marshmallows in a large bowl and sprinkle with remaining powdered sugar to coat. Store in an air tight container at room temperature for up to 1 week or in the freezer for up to 3 months.
