The Essentials
- Prep Time: 15 minutes
- Servings: 10-12 (approx. 4 cups)
- 3 large egg whites, at room temperature
- 1/2 teaspoon cream of tartar (or a pinch of salt)
- 1 cup granulated sugar
- 1/2 cup light corn syrup (or invert sugar for a smoother texture, or an additional 1/2 cup granulated sugar + 1/4 cup water)
- 1/4 cup water
- 1 teaspoon pure vanilla extract
How to Make Marshmallow Fluff

Get ready for a little kitchen magic! The key here is patience and a stand mixer to do all the heavy lifting.
Step-by-Step Guide
- Prepare Your Mixer: In the bowl of a stand mixer fitted with the whisk attachment, combine the egg whites and cream of tartar. Set aside for a moment.
- Cook the Syrup: In a medium saucepan, combine the granulated sugar, corn syrup, and water. Stir gently to combine. Place over medium-high heat and cook, without stirring once it starts bubbling, until the syrup reaches 240°F (115°C) on a candy thermometer. This is the “soft ball” stage.
- Start Whipping: Just as your syrup approaches 230°F (110°C), start whipping the egg whites on medium speed until soft peaks form. Do not over-whip at this stage; they should still be quite soft and glossy.
- Slowly Add Syrup: Once the syrup reaches 240°F (115°C), immediately remove it from the heat. With the mixer running on low speed, very slowly and carefully pour the hot syrup in a thin, steady stream down the side of the mixing bowl (avoid pouring directly onto the whisk) into the egg whites.
- Whip to Perfection: Once all the syrup is added, increase the mixer speed to high and continue to whip for 8-10 minutes, or until the Marshmallow Fluff is very thick, glossy, and has cooled down to room temperature. The mixture should hold stiff peaks when the whisk is lifted.
- Stir in Vanilla: Reduce the speed to low and add the vanilla extract, mixing until just combined.
- Serve and Store: Your homemade Fluffernutter dreams are now a reality! Use immediately or transfer to an airtight container. It will thicken further as it cools completely.
Fun Twists & Serving Ideas

The beauty of homemade Marshmallow Fluff is its endless versatility! Here are some of my favorite ways to enjoy this sweet delight:
- Classic Fluffernutter: The ultimate peanut butter and fluff sandwich. A nostalgic treat!
- Hot Chocolate Topping: A generous dollop on top of hot cocoa for an instant upgrade.
- S’mores Dip: Spread in an oven-safe dish, lightly toast under the broiler, and serve with graham crackers and chocolate.
- Dessert Topping: Perfect for pies, tarts, cupcakes, or even a simple bowl of fruit.
- Fruit Dip: Mix with a bit of cream cheese or yogurt for a delicious, fluffy fruit dip.
- Flavor Variations: Add a touch of almond extract, peppermint extract (for holidays!), or a citrus zest during the last step for different flavor profiles.
- No-Bake Pie Filling: Fold into whipped cream for an easy, fluffy pie filling.
Common Questions About Marshmallow Fluff
- How long does homemade Marshmallow Fluff last?
- When stored in an airtight container at room temperature, it typically lasts for about 1-2 weeks. Refrigeration isn’t necessary and can sometimes make it a bit sticky.
- Can I make Marshmallow Fluff without corn syrup?
- Yes, you can! Replace the 1/2 cup corn syrup with an additional 1/2 cup granulated sugar and 1/4 cup water. The corn syrup helps prevent crystallization and keeps the fluff smoother, but it’s not strictly essential.
- What can I use Marshmallow Fluff for besides sandwiches?
- So much! It’s fantastic as a topping for hot chocolate, fruit, or desserts, used in s’mores dip, as an ingredient in no-bake pies, or even as a unique frosting for cakes and cupcakes.
- Why is my fluff not getting stiff?
- This usually means the egg whites weren’t whipped long enough after adding the syrup, or the syrup didn’t reach the correct temperature. Ensure your syrup hits 240°F (115°C) and whip the mixture on high speed until it’s very thick, glossy, and holds stiff peaks.

📍 American Cuisine • 🏷️ Dessert / Condiment
20 minutes
N/A
Makes about 2 cups (approx. 8 servings)
Approx. 120-150 calories per 1/4 cup serving
Ingredients
- ▪️ 1 1/4 cups granulated sugar
- ▪️ 1/2 cup water
- ▪️ 1/4 cup light corn syrup (optional, but helps prevent crystallization and adds chewiness)
- ▪️ 3 large egg whites, room temperature
- ▪️ 1/4 teaspoon cream of tartar (optional, for stabilization)
- ▪️ 1 teaspoon vanilla extract
Preparation
1
In a medium saucepan, combine granulated sugar, water, and light corn syrup (if using). Cook over medium heat, stirring until the sugar dissolves. Increase heat to medium-high and bring the mixture to a boil without stirring. Continue to cook until the syrup reaches 240°F (116°C) on a candy thermometer (soft-ball stage). Do not stir once boiling.
2
While the syrup is cooking, in the bowl of a stand mixer fitted with the whisk attachment, beat the egg whites and cream of tartar (if using) on medium speed until soft peaks form.
3
Once the sugar syrup reaches 240°F, immediately remove it from the heat. With the mixer running on medium-low speed, carefully and slowly pour the hot syrup in a thin, steady stream into the whipping egg whites. Avoid pouring the syrup directly onto the whisk itself.
4
Once all the syrup is incorporated, increase the mixer speed to high and continue beating for 7-10 minutes, or until the mixture is very thick, glossy, forms stiff peaks, and the mixing bowl is cool to the touch. The fluff will almost double in volume and become incredibly fluffy.
5
Beat in the vanilla extract until just combined.
6
Use the marshmallow fluff immediately or transfer it to an airtight container. It can be stored at room temperature for up to 2 days, or refrigerated for up to a week (though it may deflate slightly in the fridge).
