Tips for this recipe
Storage Instructions
At room temperature: Marshmallow frosting is best used immediately after preparing. If needed, you can leave it at room temperature for up to 6-8 hours, but avoid keeping it out for too long as it may lose its texture.
In the fridge: Store any leftover frosting in an airtight container in the refrigerator for up to 2 days. When ready to use, bring it to room temperature and rewhip slightly to restore its fluffiness.
Freezing: Freezing marshmallow frosting is not recommended as it can affect the texture and consistency when thawed. For best results, make and use fresh.

Recipe Questions
Can I use marshmallow frosting on cupcakes?
Absolutely! Marshmallow frosting is perfect for topping cupcakes. It gives them a light, airy finish, and pairs well with all kinds of flavors.
Will marshmallow frosting hold up in hot weather?

Can I toast marshmallow frosting like meringue?
Yes! Marshmallow frosting can be toasted using a kitchen torch for that delicious s'mores-style flavor. It gives the frosting a slight caramelized texture and appearance.
Is marshmallow frosting the same as meringue?
Marshmallow frosting is very similar to Swiss meringue, as both are made by gently heating egg whites and sugar. However, marshmallow frosting has a softer, more melt-in-your-mouth texture that resembles marshmallows.
Can I flavor marshmallow frosting?
Yes! You can easily flavor your marshmallow frosting by adding extracts, like almond or lemon, or even mixing in cocoa powder for a chocolate version. Just add these after you’ve whipped the frosting to peaks.
