For the Syrup
- Water – Provides essential moisture for a smooth syrup base.

For the Fluff
- Egg Whites – The secret to achieving that amazing fluffiness; they should be at room temperature for optimal whipping.
- Cream of Tartar – Stabilizes egg whites, helping them achieve those beautiful peaks; optional but beneficial for fluffiness.
- Vanilla Extract – Adds a delightful flavor; almond extract can be substituted or you can omit it for a more neutral taste.
Now you’re set to create your light and dreamy Marshmallow Fluff!
Step‑by‑Step Instructions for Easy Homemade Marshmallow Fluff
Step 1: Prepare Syrup
In a heavy-bottomed saucepan, combine 1/3 cup water, 3/4 cup sugar, and 3/4 cup light corn syrup. Heat the mixture over medium-high heat without stirring until it reaches 240°F, also known as the soft ball stage. You’ll know it’s ready when the syrup turns clear and begins to bubble vigorously.
Step 2: Whip Egg Whites
While your syrup is cooking, place 3 large egg whites and 1/2 teaspoon of cream of tartar in a mixing bowl. Using a stand mixer or hand whisk, beat the egg whites on medium speed for about 3-4 minutes, or until soft peaks form. They should hold slightly when removed from the whisk, creating a dreamy cloud-like texture that’s essential for your marshmallow fluff.
Step 3: Combine Mixtures
Once your sugar syrup reaches 240°F, and your egg whites are whipped to perfection, it’s time to combine. With the mixer running on medium speed, carefully pour the hot syrup into the whipped egg whites in a slow, steady stream. Be cautious to avoid splattering and ensure an even mix for a stable and fluffy marshmallow fluff.
Step 4: Whip Until Fluffy
After incorporating the syrup, increase the mixer speed to medium-high and continue whisking for 7-8 minutes. Watch for the mixture to thicken and turn glossy, reaching a light and airy consistency. Finally, add 1 teaspoon of vanilla extract and mix until fully incorporated, enhancing the delicious flavor of your homemade marshmallow fluff.
Step 5: Cool & Store
Once ready, remove the bowl from the mixer and allow the marshmallow fluff to cool completely. It can be used right away or stored in an airtight container at room temperature. Make sure the fluff is sealed properly, where it will remain fresh and delightful for up to two weeks, ready to elevate your desserts or sandwiches whenever you need.

Homemade Marshmallow Fluff Recipe FAQs
How do I know if my egg whites are at the right temperature?
Absolutely! For the best results, your egg whites should be at room temperature, which usually takes about 30 minutes if they’re cold from the fridge. You can test this by gently touching the eggs; they should feel slightly warm to the touch, which helps them whip to a better volume and creates that fluffy texture you’re after.
How should I store leftover marshmallow fluff?
To keep your marshmallow fluff fresh, store it in an airtight container at room temperature for up to 2 weeks. Make sure the container is sealed tightly to prevent air from getting in and altering its texture. If you find yourself with extra marshmallow fluff, you can also refrigerate it, but for the best consistency, it’s best enjoyed at room temperature.
Can I freeze marshmallow fluff?
Yes, you can freeze your homemade marshmallow fluff! Just transfer it to an airtight, freezer-safe container, taking care to remove as much air as possible. It can be frozen for up to 6 months. When you’re ready to use it, simply thaw it in the fridge overnight. If it seems a bit thick after thawing, use a mixer on low speed to rewhip it back to that dreamy fluffiness.
What should I do if my marshmallow fluff isn’t thickening properly?
If your marshmallow fluff isn’t thickening as it should, it might be due to a few factors. Make sure all your mixing bowls and utensils are completely grease-free because any residue can prevent the egg whites from whipping properly. If using a stand mixer, ensure that the whisk attachment is properly secured and clean. If those checks don’t resolve the issue, try whipping a bit longer; it typically takes around 7-8 minutes for the fluff to reach that perfect consistency.
Is marshmallow fluff safe for pets or those with allergies?
While marshmallow fluff is a treat for humans, it’s not safe for pets due to its sugar content and egg whites, which can be harmful to dogs if consumed in large amounts. Additionally, if you or someone you’re serving has egg allergies or dietary restrictions, it’s important to consider that this recipe does include egg whites. Always feel free to substitute or modify recipes to accommodate dietary needs.
How do I ensure my marshmallow fluff has the best flavor?
To enhance the flavor of your marshmallow fluff, I recommend using pure vanilla extract. Add 1 teaspoon during the final mixing stage. If you’re feeling adventurous, try substituting some of the vanilla with almond extract or even a splash of flavored extracts like peppermint or coconut for a unique twist!
