Fluffy Marshmallow Icing
Light and fluffy marshmallow icing offers a sweet, airy texture with a hint of vanilla, perfect for decorating cakes and cupcakes for special occasions and celebrations.
Ingredients
Instructions
- Combine sugar, water, and cream of tartar in a saucepan.
- Bring to a rapid boil until syrup spins a 6-inch to 8-inch thread (242°F) on a candy thermometer.
- Meanwhile, in a mixing bowl, beat egg whites until soft peaks form.
- Add quartered marshmallows to the hot syrup and stir until marshmallows are melted and smooth.
- Gradually pour the hot marshmallow syrup into the beaten egg whites, beating constantly.
- Add vanilla and continue beating until the mixture is fluffy and holds its shape.
Tips & Substitutions
For a fluffier icing, ensure your egg whites are at room temperature before beating. If you don't have cream of tartar, you can substitute it with an equal amount of lemon juice or white vinegar. Use mini marshmallows for easier melting, but adjust the quantity if needed. If the syrup cools too much before mixing, gently reheat to maintain fluidity.
Serving Suggestions
This Fluffy Marshmallow Icing is perfect for topping cakes, cupcakes, or even as a dip for fruits. It pairs beautifully with a slice of Blueberry Whipped Cream Pie or can be used to enhance a simple chocolate cake. Consider adding colorful sprinkles or toasted nuts for added texture and visual appeal.
Storage & Reheating
Store any leftover icing in an airtight container in the refrigerator for up to three days. Before using, allow it to come to room temperature and rewhip briefly to restore its fluffiness. Avoid freezing, as the texture may change significantly upon thawing.

Frequently Asked Questions
Can I use powdered sugar instead of granulated sugar?
While you can use powdered sugar, it may result in a denser icing. Granulated sugar helps create the perfect structure and fluffiness, so stick to the recipe for best results.
What can I do if my icing is too runny?
If your icing is too runny, try beating it for a longer time to incorporate more air. If that doesn’t help, you can add a little more melted marshmallow or let it sit at room temperature for a short while to thicken.
Is there a way to make this icing vegan?
To make a vegan version, substitute egg whites with aquafaba (the liquid from canned chickpeas) and whip it until stiff peaks form. Use a vegan-friendly sugar and marshmallows to maintain the fluffiness and sweetness.
