How to Make Marshmallow Fluff
I recommend using a candy thermometer to make this recipe as it takes the guesswork out of getting the right temperature which is the key to success here!
- Preparation: Begin by placing egg whites and cream of tartar in a large bowl of an electric mixer. Fit the hand mixer with the beater attachment. You can also use a stand mixer with whisk attachment.
- Heat: In a medium saucepan, combine water, sugar, and syrup. Cook over medium heat, stirring constantly until it boils. Attach a candy thermometer to keep an eye on the temperature.
- Whip: As the sugar syrup cooks, start whipping the egg whites until foamy.
- Combine: Once sugar mixture reaches the right temperature, drizzle it into egg whites, continuing to whip. Beat on high speed until the mixture doubles in size and soft peaks form. Add vanilla and beat for an additional minute.
Expert Tips
These tips will help you make the best homemade marshmallow fluff!
- Ensure the sugar mixture reaches the correct temperature so you end up with the right consistency.
- Add the hot sugar mixture very slowly to the egg whites to avoid cooking them.

Recipe FAQs
Store your homemade marshmallow fluff in a covered in an airtight container at room temperature. No need to keep it in the refrigerator. It will keep well for up to 2 weeks on the counter.
If it goes flat, you can either re-whip it by hand or add it back to the mixer and whip again.
Grease or even a speck of egg yolk can prevent your egg whites from whipping up into a meringue consistency. Try wiping your equipment with lemon juice first then whipping your egg whites.
Other marshmallow desserts we love include s’mores popcorn, s’mores cookies and mini s’mores cups.
