A cloud-like confection of whipped sugar, egg whites, and gelatin, marshmallows are a sweet, springy treat that dissolves on the tongue. Their nutrition is almost pure carbohydrate, with a negligible amount of protein and virtually no fat or fiber.

↓ Full nutritionPeople love marshmallows for their uniquely soft, pillowy texture and sweet, vanilla-tinged flavor that brings immediate comfort. They are cherished for their versatility, from being toasted over a campfire to melting into a gooey topping for hot cocoa or baking into treats like Rice Krispie squares.
The primary downside is their very high sugar content (over 57g per 100g), which can cause rapid blood-sugar spikes and offers little nutritional benefit. To mitigate this, practice strict portion control and pair a marshmallow with a source of protein or healthy fat (like nuts or a piece of cheese) to slow sugar absorption. Those with severe egg allergies should check labels, as traditional recipes use egg whites.
The original marshmallow confection was made from the sap of the marshmallow plant (Althaea officinalis) and was used medicinally in ancient Egypt, not as a sweet treat.

Are marshmallows vegan?
Most traditional marshmallows are not vegan because they contain gelatin, an animal-derived protein. However, many brands now offer vegan marshmallows made with plant-based gelling agents like agar-agar or carrageenan.
Why do marshmallows get sticky in humid weather?
Marshmallows are hygroscopic, meaning they absorb moisture from the air. In humid conditions, the sugar on their surface dissolves into a syrup, making them feel sticky and causing them to clump together.
Can you toast marshmallows without a campfire?
Yes! You can use an oven's broiler (place on a baking sheet and watch closely), a kitchen torch for precise control, or even the direct flame of a gas stove burner for a quick char.
