Homemade Marshmallow Fluff Ingredients
- For the Fluff
- Water – Solvent for sugar; provides necessary moisture. Use filtered water for best results.
- Sugar – Provides sweetness and structure to the fluff.
- Light Corn Syrup – Enhances sweetness and prevents crystallization. Honey or agave syrup can be used as a substitute but may alter flavor.
- Egg Whites – Create volume and structure. Ensure they are at room temperature for optimal whipping.
- Cream of Tartar – Stabilizes egg whites and improves texture. Lemon juice can be used as a substitute if needed.
- Vanilla Extract – Adds flavor richness. Use pure vanilla extract for the best taste in your Homemade Marshmallow Fluff.
Step‑by‑Step Instructions for Homemade Marshmallow Fluff
Step 1: Combine Ingredients
In a medium saucepan, mix together 1/4 cup of water, 1 cup of sugar, and 1/4 cup of light corn syrup. Place the saucepan over medium heat and avoid stirring. Allow the mixture to bubble until it reaches a temperature of 240°F on a candy thermometer, which is crucial for achieving the right texture for your Homemade Marshmallow Fluff.
Step 2: Whip Egg Whites
While the sugar syrup is heating, grab a mixing bowl and add 2 large egg whites along with 1/4 teaspoon of cream of tartar. Use a hand or stand mixer to whip the egg whites on medium speed until soft peaks start to form, roughly 4–5 minutes. The egg whites should become frothy and glossy, ready to create that delightful fluff.
Step 3: Add Syrup Gradually
Once the syrup hits 240°F, carefully remove it from heat. With the mixer on medium speed, slowly drizzle the hot syrup into the whipped egg whites. Be cautious and avoid pouring too quickly to prevent cooking the egg. This step infuses sweetness while maintaining the fluff’s airy texture, blending perfectly for your Homemade Marshmallow Fluff.
Step 4: Whip Until Thick
After incorporating the syrup, increase the mixer speed to high, and whip the mixture for about 7-8 minutes. You’ll notice it thickening and becoming glossy, forming stiff peaks. This is when you’ll see your Homemade Marshmallow Fluff transform into a fluffy, cloud-like treat that’s perfect for your favorite desserts.
Step 5: Final Touches
Once you’ve achieved a thick, glossy texture, add 1 teaspoon of pure vanilla extract to the bowl. Gently fold it in with a spatula to enhance the flavor of your Homemade Marshmallow Fluff. Now, let it cool for a few minutes before using it to adorn any delicious treat you desire.

Make Ahead Options
These Homemade Marshmallow Fluff options are perfect for busy cooks looking to save time during hectic weeknights! You can prepare the fluff up to 24 hours in advance; simply store it in an airtight container at room temperature to maintain its delightful texture. If you’re not planning to use it immediately, you can also refrigerate it for up to 3 days. Just be sure to give it a gentle stir before serving to restore its cloud-like fluffiness. For longer storage, consider freezing the fluff in an airtight container for up to 6 months; just thaw it before using. By prepping Homemade Marshmallow Fluff ahead of time, you’ll have this dreamy treat ready to elevate your desserts with minimal effort when the cravings hit!

Homemade Marshmallow Fluff Recipe FAQs
How do I choose the right egg whites?
Absolutely! It’s best to use room temperature egg whites for optimal whipping. Cold eggs don’t whip as well as those at room temperature, so let them sit out for about 30 minutes before you start. If you’re short on time, place the eggs in a bowl of warm water for a few minutes to help them warm up quickly!
How should I store Homemade Marshmallow Fluff?
To keep your Homemade Marshmallow Fluff fresh, store it in an airtight container at room temperature for up to 2 weeks. For longer storage, you can refrigerate it, and it should stay good for about 3 weeks. Just remember to seal it tightly to preserve that wonderful fluffiness!
Can I freeze Homemade Marshmallow Fluff?
Yes, you can freeze your fluff! Simply place it in an airtight container or a freezer-safe bag and it will keep for up to 6 months. For best results, let it thaw in the fridge overnight before using. If it seems a bit stiff after thawing, a quick whip with a mixer will restore its creamy texture!
What should I do if my fluff is too runny?
If your Homemade Marshmallow Fluff turns out runny, don’t worry! It might mean the egg whites weren’t whipped to stiff peaks or the syrup didn’t reach the right temperature, which is crucial for thickening. You can try whipping it for a little longer to see if it gains volume. If not, consider slowly reheating your fluff over low heat while mixing, aiming to reintroduce air and achieve that perfect consistency.
Is Homemade Marshmallow Fluff gluten-free?
Absolutely! Homemade Marshmallow Fluff is inherently gluten-free. All the ingredients—water, sugar, corn syrup, egg whites, cream of tartar, and vanilla extract—are naturally gluten-free.
