How to Make the Best Homemade Marshmallow Fluff
Homemade marshmallow fluff only requires a few ingredients, but the result is rich, creamy, and undeniably fluffy.
Ingredients You’ll Need
- ¾ cup granulated sugar
- ½ cup corn syrup
- ¼ cup water
- 2 large egg whites (at room temperature)
- ¼ teaspoon cream of tartar
- 1 teaspoon vanilla extract
- Pinch of salt
Step-by-Step Instructions
- Prepare the sugar syrup: In a medium saucepan, combine the sugar, corn syrup, and water. Heat over medium-high, stirring occasionally, until the mixture reaches 240°F (use a candy thermometer).
- Whip the egg whites: While the syrup is heating, use a stand mixer to beat the egg whites and cream of tartar on medium-high speed until soft peaks form.
- Slowly add the syrup: Once the sugar syrup reaches 240°F, slowly pour it into the egg whites while continuing to mix on low speed. Be careful not to splash!
- Increase the speed: After all the syrup is added, increase the mixer speed to high and whip for 7–8 minutes until the mixture is thick, glossy, and fluffy.
- Add vanilla and salt: Once the fluff has cooled slightly, add the vanilla extract and salt. Mix for another 1 minute until fully combined.
- Store: Transfer the marshmallow fluff to an airtight container and store at room temperature for up to 2 weeks.
Tips for Perfect Marshmallow Fluff
- Use a candy thermometer: Precision is key! Make sure the sugar syrup reaches exactly 240°F for the perfect texture.
- Room temperature eggs: This helps them whip better and incorporate air more easily.
- Don’t overmix: Once the fluff is shiny and holds stiff peaks, stop mixing to avoid deflating it.
How to Store Homemade Marshmallow-Fluff
Homemade marshmallow fluff can be stored in an airtight container at room temperature for up to 2 weeks. If you prefer to store it longer, keep it in the refrigerator for up to 1 month. For a fluffier consistency after refrigeration, let it come to room temperature before using.

FAQs

Yes! You can use aquafaba (chickpea water) instead of egg whites and opt for a corn syrup substitute like maple syrup. The texture will be similar, though not identical.
2. How do I make marshmallow fluff thicker?
If you prefer a thicker consistency, try adding less water to the sugar syrup or whip the egg whites for a few extra minutes.
3. What’s the difference between marshmallow fluff and marshmallows?
Marshmallow fluff is softer, creamier, and spreadable, while marshmallows are firm and hold their shape. Both share similar ingredients, but marshmallows typically contain gelatin, which fluff does not.
