What Is Marshmallow Fluff?
Marshmallow fluff is a soft, spreadable marshmallow cream made by whipping hot sugar syrup into beaten egg whites until it becomes thick, glossy, and fluffy. Unlike regular marshmallows, marshmallow fluff never sets into firm squares. Instead, it remains smooth and spreadable.
It has been a favorite in American kitchens for over a century and is especially popular in New England, where the famous fluffernutter sandwich originated.

Common Mistakes to Avoid
The Syrup Crystallized
This usually happens if sugar crystals form on the sides of the pan.
Fix:
- Avoid stirring once the syrup begins boiling.
- Brush the sides of the pan with water using a pastry brush if needed.
My Fluff Is Runny
Possible causes:
- Syrup didn’t reach 240°F.
- Egg whites weren’t whipped enough.
- Syrup was poured too quickly.
My Fluff Is Too Thick
Usually caused by overheating the sugar syrup.
A candy thermometer is one of the best kitchen tools for consistent results.
Grainy Texture
This almost always means the sugar crystallized during cooking.
Use fresh sugar and avoid unnecessary stirring.
