Homemade Corn Syrup-Free Marshmallows Recipe
Introduction
Homemade marshmallows are a delightful treat that melts in your mouth. This recipe creates fluffy, pillowy marshmallows without any corn syrup, making them a great option for those looking for a simpler ingredient list.

Ingredients
- 2 tablespoons gelatin (2 envelopes Knox)
- 1 cup (8 fl oz / 225 ml) cold water, divided
- 2 cups (16 oz / 450 g) granulated sugar
- ½ cup (1⅓ oz / 28 g) powdered sugar
- ¼ teaspoon salt
- 2 teaspoons vanilla extract
Instructions
- Step 1: Dust a 9-inch square baking pan liberally with powdered sugar.
- Step 2: In a small bowl, mix the gelatin with ½ cup of cold water. Set aside for 10 minutes to allow the gelatin to bloom.
- Step 3: In a pot, combine the remaining ½ cup cold water and granulated sugar. Stir gently over medium heat until the sugar dissolves.
- Step 4: Add the bloomed gelatin to the pot and bring the mixture to a rolling boil without stirring until it reaches 240°F (115°C).
- Step 5: Carefully remove the pot from heat and pour the hot mixture into the bowl of an electric mixer.
- Step 6: Add the salt and vanilla extract.
- Step 7: Using the whisk attachment, beat on low speed for 2 minutes, then increase to high and continue beating until the mixture is soft, fluffy, and has doubled in volume, about 10-15 minutes.
- Step 8: Pour the marshmallow mixture into the prepared pan and smooth the top with a spatula. To prevent sticking, grease the spatula lightly with flavorless oil.
- Step 9: Let the marshmallows cool uncovered in the pan for at least 3 hours or until firm. Lightly dust the top with powdered sugar once set.
- Step 10: Use a small round cookie cutter to cut out shapes, dust with powdered sugar, and decorate as desired. Melted chocolate and colored candy melts work well for eyes and features. Enjoy plain or in hot chocolate!
Tips & Variations
- For a different flavor, try adding peppermint extract or almond extract instead of vanilla.
- To prevent sticking when cutting marshmallows, dust your cutter with powdered sugar or cornstarch.
- Use light corn syrup as a substitute if you prefer the traditional marshmallow texture, but this recipe is perfect without it.
- Store marshmallows in an airtight container to keep them soft and fresh longer.
Storage
Store homemade marshmallows in an airtight container at room temperature for up to two weeks. To reheat and soften slightly, place marshmallows in warm beverages like hot chocolate or toast lightly over a fire for a delicious treat.

FAQs
Can I use powdered gelatin instead of gelatin sheets?
Yes, this recipe uses powdered Knox gelatin, which is easy to measure and widely available. If using gelatin sheets, follow the package instructions to bloom and dissolve them properly.
Why does the recipe avoid corn syrup?
This recipe skips corn syrup to provide a cleaner ingredient list and a more natural flavor. Using gelatin and sugar alone creates a light and fluffy marshmallow without the need for corn syrup’s stabilizing properties.

Ingredients
Gelatin Mixture
- 2 tablespoons gelatin (2 envelopes Knox)
- 1/2 cup (4 fl oz / 115 ml) cold water, divided
Syrup
- 1/2 cup (4 fl oz / 115 ml) cold water, divided
- 2 cups (16 oz / 450 g) granulated sugar
Additional Ingredients
- 1/2 teaspoon salt
- 2 teaspoons vanilla extract
- 1/2 cup (1 1/3 oz / 28 g) powdered sugar, for dusting
Instructions
- Prepare Pan: Dust a 9-inch square baking pan liberally with powdered sugar to prevent sticking.
- Bloom Gelatin: In a small bowl, combine gelatin with 1/2 cup cold water and set aside for 10 minutes to allow the gelatin to soften and bloom.
- Dissolve Sugar: In a medium pot, combine the remaining 1/2 cup cold water and granulated sugar. Heat over medium, stirring until the sugar dissolves.
- Boil Mixture: Add the bloomed gelatin to the pot. Bring the mixture to a rolling boil without stirring and continue until it reaches a temperature of 240°F (115°C) on a candy thermometer.
- Transfer to Mixer: Remove the hot syrup from heat and pour it into the bowl of an electric mixer.
- Add Flavor and Salt: Stir in the salt and vanilla extract to the hot mixture.
- Whip Mixture: Using the whisk attachment, beat the mixture on low speed for 2 minutes, then increase to high speed and continue beating until the mixture is soft, glossy, and has roughly doubled in volume, about 10–15 minutes.
- Set in Pan: Pour the marshmallow mixture into the prepared pan and smooth the surface with a spatula lightly greased with flavorless oil to prevent sticking, due to the sticky texture.
- Cool and Firm: Let the marshmallows cool uncovered at room temperature until firm, for a minimum of 3 hours.
- Finish and Cut: Lightly dust the top with sifted powdered sugar. Use a small round cookie cutter to cut marshmallows into shapes. Optionally, dust the pieces with more powdered sugar and decorate with melted chocolate or colored melts to create faces for fun snowmen heads. Enjoy plain or as a topping for hot beverages.
Notes
- Ensure the candy thermometer temperature is accurate at 240°F for the perfect marshmallow texture.
- Using powdered sugar to dust the pan and marshmallows prevents them from sticking.
- You can flavor your marshmallows with other extracts or add-ins but keep gelatin and sugar proportions consistent.
- Do not stir the syrup once it reaches the boiling stage to avoid crystallization.
- Allow marshmallows to cool fully at room temperature before cutting to ensure clean shapes.
- Store finished marshmallows in an airtight container to maintain freshness.
