Whether you’re swirling it into fudge or slathering it onto bread for a next-level fluffernutter, there’s nothing quite like the real thing you whip up yourself.

Ingredients You’ll Need

These basic ingredients are the secret to the ultimate homemade Marshmallow Fluff. Each plays a starring role, from creating silky texture to bringing in that classic, comforting flavor—all with zero fuss.

• Water: It helps dissolve the sugar and gets the syrup cooking, so everything melds perfectly.
• Granulated Sugar: Delivers essential sweetness and structure to your fluff.
• Light Corn Syrup: Prevents crystallization and guarantees that iconic stretchy texture.
• Egg Whites (room temperature): Whipped into gorgeous airy peaks, these are the backbone of the fluff.
• Cream of Tartar: Stabilizes the egg whites, making sure your mixture is light, glossy, and never weepy.
• Vanilla Extract: The flavor punch that takes your marshmallow fluff over the top!

How to Make How to Make Marshmallow Fluff

Step 1: Prepare the Sugar Syrup

Start by combining the water, sugar, and corn syrup in a medium, heavy-bottomed saucepan. This trio is the foundation for your syrup, which gives the fluff its signature sticky-sweet backbone. Secure a candy thermometer to the pan, then set it over medium-high heat and let it work its magic—no need to stir! Letting the mixture bubble away undisturbed keeps it crystal-clear and perfectly smooth.

Step 2: Whip the Egg Whites

While your syrup is heating up, pop the egg whites and cream of tartar into the bowl of a stand mixer fitted with the whisk attachment, or grab a large bowl and an electric hand mixer if you prefer. Whisk them together for about 3 to 4 minutes, just until you reach soft, billowy peaks. This is when the mixture will look foamy and dreamy, and you’ll clearly see ridges forming when you lift the whisk.

Step 3: Reach Syrup Temperature

Keep your eyes on the thermometer as your sugar syrup heats. You want it to hit the soft-ball stage, which is 240°F. This precise temperature is crucial for the right marshmallow texture—sticky, stretchy, and gorgeously glossy. Take it off the heat carefully once you’ve reached the magic number.

Step 4: Combine Sugar Syrup and Egg Whites

With your mixer running on medium speed, slowly (and I mean really slowly) drizzle the hot syrup into the whipped egg whites. If you’re using a hand mixer, ask a friend to help—even just to steady the bowl or the saucepan. Pouring too quickly can deflate your beautiful whites, so take your time with this step.

Step 5: Whip to Perfection

Once all the syrup is blended in, crank the speed up to medium-high. You’ll notice the mixture going a bit flat for a moment—that’s totally normal! Just keep whipping for 7 to 8 minutes, and the magic happens: the fluff thickens, becomes super glossy, and doubles in volume. When it’s thick enough to form perfect, soft peaks, whisk in the vanilla extract for that classic flavor burst.

Step 6: Cool and Store

Before you dive in, let your homemade marshmallow fluff cool completely. Spoon it into an airtight container and store it at room temperature—it’ll keep its dreamy texture for up to two weeks. Grab a spoon and taste how to make Marshmallow Fluff shines compared to anything store-bought!

Make Ahead and Storage

Storing Leftovers

Keep your marshmallow fluff in a clean, airtight container at room temperature, away from direct sunlight. It stays fluffy and delicious for up to two weeks, ready for sandwiches, desserts, or impromptu midnight snacks!

Freezing

While marshmallow fluff can technically be frozen, its airy texture may suffer and become grainy once thawed. For best results, make a fresh batch—you won’t regret it, and the process is quick enough to whip up whenever the craving calls.

Reheating

If your fluff firms up a touch, give it a gentle stir or let it sit at room temperature for 15-20 minutes before using. Don’t microwave, as this can make it watery or cause the sugar to seize. A quick whisk usually brings back that signature cloud-like smoothness.
