These Homemade Marshmallows are tender and cloudlike, with a sweet vanilla aroma and a chewy, melt-in-your-mouth texture that commercial versions rarely match. Freshly whipped, they have a glossy sheen and a springy bite that is perfect for hot cocoa, s’mores, or simply snacking straight from the jar. This recipe is ideal for gifting at the holidays, making with kids on a rainy afternoon, or elevating desserts that need a little showstopping topping.

Ingredients

• 1/3 cup (40g) confectioners’ sugar, Mixes with cornstarch to prevent sticking and gives the outside a soft finish.
• 3 tablespoons (24g) cornstarch, Blends with confectioners’ sugar to create the dusting that keeps marshmallows from sticking.
• 3/4 ounce (21g) unflavored gelatin (3 standard 1/4-ounce packets), Provides structure and the classic springy chew.
• 1 cup (240ml) cold water, divided, Used to bloom gelatin and to dissolve the sugar syrup.
• 1 cup (325g) light corn syrup, Keeps the marshmallows soft and prevents crystallization in the sugar syrup.
• 1 and 1/2 cups (300g) granulated sugar, The primary sweetener that forms the body of the marshmallow.
• 1/4 teaspoon salt, Balances sweetness and enhances flavor.
• 1 tablespoon pure vanilla extract, Adds a warm, familiar vanilla aroma and flavor in the final minute of whipping. If you prefer a different note, vanilla can be swapped for another extract sparingly.

Step-by-step Instructions

1. Prepare the pan. Generously spray the bottom and sides of a 9 by 13 inch glass or ceramic baking pan with nonstick cooking spray. Dust the pan evenly with a mixture of the confectioners’ sugar and cornstarch. Reserve the remaining mixture for coating later. A well-dusted pan makes removal much easier and gives neat edges similar to the coating used in this churro bites pan prep.

2. Bloom the gelatin. Place the gelatin and 1/2 cup of the cold water in the bowl of a stand mixer. Let the gelatin sit and bloom while preparing the hot syrup. Do not heat the gelatin at this stage.

3. Make the sugar syrup. In a medium saucepan, combine the remaining 1/2 cup water, corn syrup, granulated sugar, and salt over medium heat. Stir until the sugar fully dissolves, then stop stirring and let the mixture cook until it reaches the soft ball stage, 235 to 240 degrees F. Using a candy thermometer gives the most reliable result.

4. Combine syrup and gelatin. Remove the syrup from heat and let it sit for 5 minutes. While the mixer runs on low speed, slowly pour the hot syrup into the bloomed gelatin in a thin stream. Aim for a steady pour to avoid splashing and to keep the gelatin from clumping.

5. Whip until voluminous. Increase mixer speed to high and whip until thick, glossy, and tripled in volume, about 10 to 15 minutes. Add the vanilla in the last minute of whipping to preserve its fresh flavor. The mixture should hold soft peaks and look like thick marshmallow fluff.

6. Set in the pan. Pour the whipped marshmallow mixture into the prepared pan and smooth the top with a lightly oiled spatula. Let sit uncovered at room temperature for at least 6 hours, or until firm. Avoid refrigerating, which can add moisture to the texture. For serving ideas that use set candies, see a simple spreading method in this homemade jam guide.

7. Cut and coat. Once firm, dust a cutting board with the remaining sugar and cornstarch mixture. Invert the marshmallows onto it, cut into squares, and toss each square lightly in the sugar mixture to coat the edges. A sharp knife or lightly oiled cookie cutter makes neat shapes.

8. Store. Store in an airtight container at room temperature for up to 2 weeks.

Tips, Storage & Variations

• Tip: Use a candy thermometer for the syrup to ensure you reach the soft ball stage. Accuracy matters more than guessing by eye.
• Tip: Lightly oil your knife or spatula between cuts for clean edges.
• Tip: If the marshmallows stick to your hands while coating, dust your palms with the sugar and cornstarch mixture.
• Storage: Keep marshmallows in an airtight container at room temperature. Place parchment between layers to prevent sticking. They will stay fresh up to 2 weeks.
• Freezing: Marshmallows freeze well. Flash freeze cut squares on a tray, then transfer to a freezer bag for up to 3 months. Thaw at room temperature before serving.
• Flavor variations using existing ingredients: Keep the ratios identical and stir a tiny amount extra vanilla into the whipped mixture for a stronger vanilla flavor. For a subtle change, reduce the vanilla slightly or add the vanilla a few seconds earlier to mellow the note. For creative pairings, serve alongside spreads from a simple homemade jam guide or use them to top treats like those shown in this churro bites tips article for dessert inspiration.
