Ingredients

This homemade marshmallow recipe uses a short ingredient list, but each ingredient has an important job.

• Unflavored gelatin: Gives the marshmallows their bounce, structure, and fluffy chew.
• Cold water: Blooms the gelatin so it dissolves properly and whips smoothly.
• Granulated sugar: Creates the sweet base of the marshmallow syrup.
• Light corn syrup: Helps prevent crystallization and gives the marshmallows a smooth texture.
• Kosher salt: Balances the sweetness.
• Vanilla extract: Gives the marshmallows that classic sweet vanilla flavor.
• Confectioners’ sugar: Keeps the marshmallows from sticking to the pan, knife, and each other.

How to Make Homemade Marshmallows

Bloom the Gelatin

Add the unflavored gelatin and cold water to the bowl of a stand mixer fitted with the whisk attachment. Let the gelatin sit while you prepare the sugar syrup. This step is what helps your homemade marshmallows set with that soft, springy texture.

Make the Sugar Syrup

In a medium saucepan, combine the granulated sugar, light corn syrup, and salt. Cook over medium heat until the sugar dissolves, then increase the heat and cook until the syrup reaches 240°F on a candy thermometer.

This temperature matters. It gives the marshmallows enough structure to set without turning them tough or rubbery.

Whip the Marshmallow Mixture

Turn the mixer on low and carefully stream the hot syrup into the bloomed gelatin. Once the syrup is added, increase the mixer speed to high and whip until the mixture becomes thick, glossy, white, and fluffy.

This usually takes about 12 to 15 minutes. Add the vanilla extract near the end and mix just until combined.

Prepare the Pan

Coat a 9×12-inch non-metal baking dish with nonstick spray, then generously dust the bottom and sides with confectioners’ sugar. Do not be shy here. Marshmallows are sticky little clouds with commitment issues.

Pour and Set

Spread the marshmallow mixture into the prepared pan. Smooth the top as best you can, then dust with more confectioners’ sugar. Let the marshmallows sit uncovered at room temperature overnight so they can set completely.

Cut the Marshmallows

Turn the marshmallow slab out onto a cutting board dusted with confectioners’ sugar. Use a powdered-sugar-dusted knife or pizza cutter to cut the marshmallows into squares.

For homemade mini marshmallows, cut the slab into narrow strips, then cut each strip into tiny cubes. Toss all cut sides in confectioners’ sugar so they do not stick together.

Expert Tips for Perfect Homemade Marshmallows

• Use a candy thermometer. The syrup should reach 240°F for the best marshmallow texture.
• Let the gelatin bloom fully. Give it time to absorb the water before adding hot syrup.
• Pour slowly. Stream the hot syrup into the mixer carefully so it blends evenly with the gelatin.
• Whip long enough. The mixture should be thick, glossy, and dramatically increased in volume.
• Dust generously. Confectioners’ sugar keeps the marshmallow slab, knife, and cut pieces from sticking.
• Let them set overnight. Cutting too soon can make the marshmallows sticky and difficult to handle.

Troubleshooting Homemade Marshmallows

Why are my homemade marshmallows sticky?

Sticky marshmallows usually need more setting time, more confectioners’ sugar, or a little help from cornstarch. Toss the cut marshmallows in a mixture of confectioners’ sugar and cornstarch to keep the sides dry.

Why did my marshmallows turn out dense?

Dense marshmallows may not have been whipped long enough, or the syrup may not have reached the right temperature. Whip until the mixture is thick, glossy, and fluffy.

Why did my marshmallows not set?

If homemade marshmallows do not set, the gelatin may not have bloomed properly, or the sugar syrup may not have reached 240°F. Letting the marshmallows rest overnight also helps them firm up.

Homemade Marshmallow Variations

• Peppermint marshmallows: Use peppermint extract and add a red swirl for winter cocoa.
• Vanilla bean marshmallows: Add vanilla bean paste for a richer vanilla flavor.
• Chocolate marshmallows: Add cocoa powder for a chocolatey twist.
• Strawberry marshmallows: Add crushed freeze-dried strawberries to the dusting sugar.
• Homemade mini marshmallows: Cut the slab into tiny cubes for hot chocolate, cereal treats, or snack mixes.
• Holiday marshmallows: Use cookie cutters for hearts, stars, trees, or snowflakes.

Serving Ideas for Homemade Marshmallows

Homemade marshmallows are wonderful straight from the container, but they also turn simple desserts into something memorable.

• Float them in hot cocoa or coffee.
• Use them in s’mores or indoor s’mores boards.
• Layer them into dessert charcuterie boards with chocolate, graham crackers, cookies, and berries.
• Package them in jars with cocoa mix for homemade gifts.
• Cut them into small cubes for homemade mini marshmallows.
• Toast them over a campfire or kitchen torch.
• Use them to top brownies, cupcakes, or ice cream sundaes.

How to Store Homemade Marshmallows

Store homemade marshmallows in an airtight container at room temperature for up to 3 weeks. Keep them in a cool, dry place and separate layers with parchment paper if needed.

Do not refrigerate homemade marshmallows. The refrigerator can add moisture and make them sticky.

Can You Freeze Homemade Marshmallows?

Yes, you can freeze homemade marshmallows. Place them in a single layer on a baking sheet until firm, then transfer them to a freezer-safe bag or container. Freeze for up to 3 months.

Thaw at room temperature and toss with a little confectioners’ sugar before serving if they feel tacky.
