Homemade Marshmallows

Homemade marshmallows are a light, pillowy treat that melt on the tongue with a sweet, vanilla-forward flavor and a subtly chewy center. Freshly made, they have a glossy, tender surface and a clean sugar aroma that hints at campfire s’mores, hot chocolate, or decadent desserts. These marshmallows are ideal when you want a fun weekend baking project, a homemade gift, or a fluffy topping for warm drinks. The texture is soft but holds its shape when cut, and the vanilla adds a warm, familiar finish. If you like making comfort foods from scratch, they pair beautifully with other homemade snacks and small bites for cozy gatherings.

Step-by-Step Instructions

1. Generously spray the bottom and sides of a 9×13-inch baking pan with nonstick spray and dust with a mixture of the confectioners’ sugar and cornstarch. Reserve some of the mixture for coating the marshmallows later.

2. In a medium bowl, combine the unflavored gelatin and 1/2 cup of the cold water. Let the gelatin bloom for about 5 minutes until it absorbs the water and becomes spongy.

3. In a medium saucepan, combine the remaining 1/2 cup cold water, light corn syrup, granulated sugar, and the 1/4 teaspoon salt. Heat over medium, stirring until the sugar fully dissolves.

4. Continue to cook the syrup without stirring until it reaches 235 to 240 degrees F. Use a candy thermometer for accuracy. The syrup will be clear and slightly thickened at this stage.

5. Remove the saucepan from heat and let the syrup cool for 5 minutes. With your mixer running on low speed, slowly pour the hot syrup into the bloomed gelatin bowl in a thin, steady stream.

6. Increase the mixer speed to high and whip the mixture until it becomes very thick, glossy, and roughly triples in volume, about 10 to 15 minutes. Add the tablespoon of pure vanilla extract during the last minute of whipping.

7. Pour the whipped marshmallow mixture into the prepared 9×13-inch pan. Use a spatula to smooth the top evenly. Let the marshmallows set at room temperature, uncovered, for at least 6 hours or until firm.

8. Once set, dust a cutting board with the remaining confectioners’ sugar and cornstarch mixture. Invert the pan onto the board and gently remove the marshmallow slab. Cut into squares with a sharp knife or bench scraper dusted with the sugar mixture. Toss any sticky edges in the remaining dusting if desired.

9. Store finished marshmallows in an airtight container at room temperature for up to 2 weeks.

Tips, Storage & Variations

• Tips: Use a reliable candy thermometer for accurate temperature when cooking the syrup. If the syrup is undercooked the marshmallows may be too soft, and if overcooked they will be overly firm.

• Cutting tip: Oil or flour the knife lightly between cuts to get cleaner edges. A serrated knife or a pizza cutter works well for larger cuts.

• Storage: Store marshmallows in an airtight container at room temperature for up to 2 weeks. Do not refrigerate, as moisture can make them sticky.

• Freezing: Marshmallows can be frozen in a sealed container for up to 3 months. Thaw at room temperature before serving, and toss in the powdered sugar mixture if they feel tacky.

• Flavor variations using only the existing ingredients:

  • Keep the recipe the same but reduce vanilla to 1/2 tablespoon for a milder flavor.
  • For a more intense vanilla note, increase the vanilla to 1 and 1/2 tablespoons while keeping all other measurements the same.
