3-Ingredient Vanilla Bean Marshmallows

Ingredients
- 1 cup cold water, divided
- 3 tablespoons (21g) unflavored powdered gelatin
- 1 1/2 cups (300g) granulated sugar
- 1 teaspoon pure vanilla bean paste (or extract)
- Powdered sugar & cornstarch mix (for dusting)
Step-by-Step Instructions

- Bloom the Gelatin: Pour 1/2 cup of cold water into the bowl of a stand mixer. Sprinkle the powdered gelatin evenly over the water. Do not stir. Let it sit for 10 minutes to “bloom” and become firm.
- Create the Sugar Syrup: While the gelatin blooms, combine the remaining 1/2 cup of water and the granulated sugar in a medium saucepan. Stir over medium heat just until the sugar dissolves. Then, stop stirring and bring the mixture to a rapid boil. Clip a candy thermometer to the side and boil until the syrup reaches 240°F (the “soft-ball” stage). This is the secret to perfect texture.
- Whip to Perfection: With the stand mixer running on low speed, carefully pour the hot sugar syrup directly into the bloomed gelatin. Increase the speed to high and whip for a full 10-12 minutes, until the mixture is thick, glossy, white, and has tripled in volume. In the final minute, add the vanilla bean paste. This process of how to make marshmallows 3 ingredients into a luxurious foam is truly magical.
- Set and Cut: Pour the fluffy marshmallow mixture into a pan (8×8 or 9×9) that has been generously dusted with the powdered sugar/cornstarch mix. Use a lightly oiled spatula to smooth the top. Dust the top with more sugar mix. Let set at room temperature for at least 4 hours, or overnight, uncovered.
This method for homemade marshmallows without corn syrup relies on a precise sugar syrup, which is easier than you think and creates a wonderfully pure flavor.
Tips & Variations
- Flavor Twists: Add 1/4 cup cocoa powder to the sugar syrup for chocolate marshmallows. Substitute the vanilla with peppermint, almond, or coconut extract.
- Color Fun: Add a few drops of gel food coloring in the last minute of whipping for pastel clouds.
- Sweetener Swap: You can use organic cane sugar. Avoid liquid sweeteners like honey or maple syrup as they will alter the setting chemistry.
Serving & Storage

Once set, turn the marshmallow slab onto a cutting board dusted with more sugar mix. Use a pizza cutter or sharp knife dusted with powder to cut into squares. Toss each piece in the sugar mix to prevent sticking. Store in an airtight container at room temperature for up to 2 weeks. They are perfect for topping hot drinks, making s’mores, or simply enjoying as a sweet, airy treat.
Nutritional Benefits / Advantages
While still a sweet treat, homemade marshmallows give you complete control over the ingredients. You avoid artificial colors, flavors, and high fructose corn syrup found in many commercial brands. Using pure vanilla bean paste provides a richer, more authentic flavor than synthetic vanillin.
Common Mistakes to Avoid

- Not Using a Thermometer: The syrup temperature is non-negotiable. Too low, and marshmallows won’t set; too high, they become hard and chewy.
- Under-Whipping: Don’t rush the whipping time! Full volume and stability are achieved around the 10-minute mark.
- Forgetting to Dust: Generous dusting with the sugar/cornstarch mix is crucial to prevent a sticky mess when cutting and storing.

FAQs
Can I use agar-agar instead of gelatin to make these vegan?
While possible, agar-agar behaves very differently than gelatin and requires a modified process. It sets firmer and can be more brittle. For a reliable vegan marshmallow, seek out a recipe specifically formulated for agar-agar or vegan gelatin alternatives.
Why did my marshmallows turn out rubbery?
A rubbery texture usually indicates the sugar syrup was cooked to too high a temperature (above 240°F). Ensure your candy thermometer is accurate and remove the syrup from heat as soon as it hits the soft-ball stage.
How can I fix marshmallows that are too sticky?
If your cut marshmallows are still too sticky, simply toss them in more of the powdered sugar and cornstarch mixture. You can also let them sit uncovered on a wire rack for a few hours to dry out slightly on the surface.
Can I toast these homemade marshmallows?
Absolutely! They toast beautifully over a campfire or under a broiler. Because they lack stabilizers, they may melt faster than store-bought ones, so keep a close eye on them for that perfect golden brown color.
What’s the purpose of the cornstarch in the dusting mix?
Cornstarch absorbs moisture and prevents sticking much more effectively than powdered sugar alone. The classic blend is equal parts powdered sugar and cornstarch, which creates a non-stick barrier for your fluffy creations.
