Ingredients

Scale

Marshmallow Base

  • ⅔ cup water, divided
  • 3 envelopes (¼ ounce each) unflavored gelatin
  • 1 cup granulated sugar
  • 1 cup light corn syrup
  • A small pinch of kosher salt
  • 1 teaspoon pure vanilla extract
  • Red or pink gel food coloring (optional)

For Coating

  • Powdered sugar, for coating the pan and marshmallows

Instructions

  1. Gather Ingredients: Measure all ingredients precisely to ensure the best results, including dividing the water as specified.
  2. Prepare Pan: Spray a 9 x 13-inch pan with cooking spray and generously coat the surface with powdered sugar to prevent sticking.
  3. Bloom Gelatin: In a small bowl, sprinkle the gelatin over ⅓ cup of water and let it sit for about 10 minutes until fully absorbed and gelatin is softened.
  4. Cook Sugar Mixture: In a saucepan, combine the remaining ⅓ cup water, granulated sugar, light corn syrup, and kosher salt. Heat over medium-high heat, stirring until the sugar dissolves, then allow the mixture to reach 240°F (soft-ball stage) on a candy thermometer.
  5. Combine with Gelatin: Slowly pour the hot sugar mixture into the bloomed gelatin while mixing at low speed using a stand mixer or hand mixer.
  6. Whip Marshmallow: Increase mixer speed to high and whip the mixture until it becomes thick, fluffy, and lukewarm, about 10 to 15 minutes. Then fold in the vanilla extract and food coloring if using.
  7. Set in Pan: Pour and spread the marshmallow mixture evenly into the prepared pan, pressing down gently to smooth the surface.
  8. Let Set: Allow the marshmallow to set at room temperature for at least 1 hour or until firm to the touch.
  9. Cut Shapes and Coat: Using a heart-shaped cookie cutter dipped in water to prevent sticking, cut the marshmallow into hearts. Toss each heart lightly in powdered sugar to coat all sides.

Notes

  • Ensure your candy thermometer is accurate for the sugar mixture temperature to achieve the perfect marshmallow texture.
  • Coating the cookie cutter in water prevents sticking for cleaner cuts.
  • Store marshmallows in an airtight container at room temperature to maintain freshness for up to 1 week.
  • Customize colors with gel food coloring as preferred for different occasions.
