Homemade chocolate marshmallow hearts are soft, fluffy candies coated in silky, glossy chocolate. Perfect for Valentine’s Day or as a thoughtful gift, these heart-shaped treats combine creamy chocolate and airy marshmallow for a melt-in-your-mouth experience.

Ingredients

Scale
  • 12 oz (340 g) chocolate (milk, dark, or white)
  • 2 1/2 teaspoons gelatin powder
  • 3/4 cup granulated sugar
  • 1/4 cup light corn syrup
  • 3/4 cup water (divided)
  • 1 teaspoon vanilla extract
  • Powdered sugar or cocoa powder for dusting
  • Optional: Sea salt flakes, fruit purée, or edible decorations

Instructions

  1. Bloom the gelatin by sprinkling it over 1/2 cup of cold water and let it sit for 10 minutes.
  2. In a saucepan, mix sugar, corn syrup, and 1/4 cup of water. Bring to a boil and cook until the syrup reaches 240°F (soft-ball stage).
  3. Pour the syrup into the bloomed gelatin while mixing on low speed. Increase to high and whip for 8–10 minutes until fluffy. Add vanilla extract.
  4. Melt and temper 2/3 of the chopped chocolate using a double boiler or microwave in 15-second bursts, stirring often. Add the remaining chocolate and stir until smooth.
  5. Coat the inside of heart-shaped silicone molds with a thin layer of melted chocolate. Chill for 5 minutes.
  6. Pipe marshmallow filling into each cavity, leaving space at the top.
  7. Seal with more melted chocolate, smooth the surface, and chill for 30 minutes.
  8. Unmold gently and decorate with drizzled chocolate, sea salt, or sprinkles if desired.

Notes

  • Use high-quality chocolate with at least 30% cocoa butter for best texture.
  • Do not refrigerate; moisture can dull the chocolate surface.
  • Store candies in an airtight container for up to 10 days at room temperature.
  • For vegan hearts, replace gelatin with agar-agar and use dairy-free chocolate.
