Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

• powdered sugar (for dusting)

• cornstarch (for dusting)

• aquafaba (preferably no-salt-added and chilled)

• cream of tartar

• vanilla extract

For the syrup

• granulated sugar

• water

For the agar mixture

• agar-agar powder

• granulated sugar

• water

Directions

1. Prepare the pan: Line a 9-inch square pan with parchment paper and dust it generously with a mix of powdered sugar and cornstarch. This prevents sticking and allows for smooth marshmallow removal later.

2. Whip the aquafaba: In a stand mixer fitted with a whisk, combine aquafaba and cream of tartar. Whisk on medium to medium-high speed until soft peaks form—this will take about 10 minutes.

3. Make the sugar syrup: In a small saucepan, combine 1 cup granulated sugar and ⅓ cup water. Heat over medium-high without stirring until it reaches 240°F (115°C), about 10 minutes.

4. Combine syrup with aquafaba: Slowly drizzle the hot syrup into the whipped aquafaba while continuing to whisk. Keep whisking for another 5–8 minutes until the mixture becomes glossy with stiff peaks. Add the vanilla extract during this step.

5. Prepare the agar mixture: In a separate saucepan, whisk together ¼ cup sugar, ¾ cup water, and agar-agar powder. Bring to a boil and simmer for 2–3 minutes, stirring constantly.

6. Incorporate the agar: Gradually pour the agar mixture into the whipped aquafaba while whisking. Mix until fully incorporated—about 1 minute.

7. Transfer to pan: Pour the marshmallow mixture into the prepared pan. Use a spatula or lightly wet hands to smooth it into an even layer. Work quickly, as the mixture begins to set right away.

8. Let set: Cover the pan loosely with a towel and let the marshmallows set at room temperature for 4–6 hours.

9. Cut and dust: Once fully set, cut into squares and coat each piece with more powdered sugar and cornstarch to prevent sticking.

Servings and timing

This recipe yields approximately 36 marshmallows and takes about 1 hour total—20 minutes of prep, 40 minutes of cooking, and 4–6 hours of inactive setting time.

Variations

• Flavored marshmallows: Add peppermint, almond, or coconut extract in place of or alongside the vanilla.

• Colored swirls: Add a few drops of vegan food coloring and gently swirl before the mixture sets.

• Coconut coating: Dust finished marshmallows in toasted coconut for a tropical twist.

• Chocolate dipped: Dip cooled marshmallows halfway in melted vegan chocolate and let them set for a sweet coating.

• Holiday shapes: Pour into silicone molds for festive designs or themed treats.

Storage/Reheating

Store marshmallows in an airtight container at room temperature for up to 1 week. Do not refrigerate or freeze, as this can alter the texture. If they begin to stick, toss them again in a bit of the powdered sugar and cornstarch mixture.

FAQs

What is aquafaba?

Aquafaba is the liquid from canned chickpeas. It mimics egg whites and whips up into fluffy peaks, making it perfect for vegan baking.

Can I use agar flakes instead of powder?

It’s best to use agar-agar powder for accuracy. If using flakes, you’ll need to adjust the quantity and cooking time as flakes take longer to dissolve.

Do vegan marshmallows melt?

Yes, these marshmallows melt beautifully in hot cocoa or baking recipes like s’mores bars and crispy treats.

Why are my marshmallows sticky?

If not coated well in the powdered sugar and cornstarch mix, they may become sticky. Make sure to dust generously after cutting.

Can I use a hand mixer?

A stand mixer is strongly recommended due to the extended whipping time required for aquafaba. A hand mixer may overheat or under-whip.

Can I flavor the marshmallows?

Absolutely! Add your favorite extracts or even fruit powders to customize the flavor.

Are these marshmallows safe for toasting?

Yes, they toast nicely over a fire or kitchen torch. Just be mindful not to burn them as they may brown quickly.

Can I use homemade aquafaba?

Yes, as long as it’s thick enough to whip. Chilling helps achieve better volume.

Why did my marshmallows not set?

Check the agar quantity and ensure it was boiled long enough to activate. Agar must reach a full boil to work properly.

Can I make mini marshmallows?

Yes, spread the mixture into a larger pan for thinner pieces and cut into smaller cubes once set.

Conclusion

Vegan Marshmallows are a delightful and versatile treat that rivals traditional marshmallows in texture and flavor—without the gelatin. With just a few plant-based ingredients and some simple steps, you can create soft, fluffy marshmallows perfect for any occasion. Whether you're toasting them, melting them, or eating them as-is, these are sure to become a go-to favorite in your vegan dessert lineup.
