Marshmallow Hearts Recipe
Introduction
These delightful Marshmallow Hearts are a sweet treat perfect for special occasions or anytime you want a fun, homemade candy. Soft, fluffy, and lightly coated with powdered sugar, they offer a lovely texture and a hint of vanilla. Plus, you can customize their color to fit any theme!

Ingredients
- Powdered sugar, for coating the pan
- 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, if desired
Instructions
- Step 1: Gather all ingredients and measure them accurately to ensure the best results.
- Step 2: Prepare a 9 x 13-inch pan by spraying it with cooking spray and coating it generously with powdered sugar to prevent sticking.
- Step 3: In a small bowl, bloom the gelatin by sprinkling it over ⅓ cup of the water. Let it sit for about 10 minutes until it becomes soft.
- Step 4: In a saucepan, combine the remaining ⅓ cup water, granulated sugar, corn syrup, and a pinch of kosher salt. Cook over medium-high heat until it reaches 240°F (soft-ball stage) on a candy thermometer.
- Step 5: Carefully add the hot sugar mixture to the bloomed gelatin while mixing on low speed using a stand mixer or hand mixer.
- Step 6: Continue mixing until the mixture thickens and becomes glossy. Stir in the vanilla extract and gel food coloring if using.
- Step 7: Pour and spread the marshmallow mixture evenly into the prepared pan. Press down gently to smooth the surface.
- Step 8: Allow the marshmallow to set for at least 1 hour or until firm to the touch.
- Step 9: Once set, use a wet heart-shaped cookie cutter to cut out marshmallow hearts. Coat each piece lightly with powdered sugar to prevent sticking.
Tips & Variations
- Use a kitchen scale for precise measurements, especially when working with gelatin and sugar, for consistent texture.
- Add a few drops of peppermint or almond extract instead of vanilla for a different flavor twist.
- If you prefer softer marshmallows, reduce the cooking temperature slightly below 240°F.
- Dust the cut marshmallows with a mix of powdered sugar and cornstarch to reduce stickiness further.
Storage
Store your marshmallow hearts in an airtight container at room temperature for up to 2 weeks. Keep them away from heat and humidity to maintain their texture. If they become sticky, lightly dust with powdered sugar before serving. There’s no need to refrigerate or freeze, as this can affect their softness.

FAQs
Can I make marshmallows without a candy thermometer?
While possible, a candy thermometer ensures you reach the precise temperature needed for the perfect texture. Without one, you risk under or overcooking the sugar mixture, resulting in marshmallows that are too soft or too hard.
How do I prevent marshmallows from sticking together?
Coating your marshmallow hearts with powdered sugar helps prevent sticking. You can also lightly dust them with a mixture of powdered sugar and cornstarch for extra protection. Storing them in an airtight container separated by parchment paper can also help.
