This Marshmallow Buttercream Frosting recipe is so fluffy and super easy to make, it only takes 5 minutes! It is made with marshmallow fluff and is the perfect for topping cupcakes, frosting cakes, or using on your favorite desserts. It's sweet and creamy and delicious any time of year!
Slather this on to any cake or cupcake right away. If you want to pipe it and have it hold its shape you will need to chill it for 30 mins first.
Storage
Storing: Store the marshmallow buttercream frosting in an airtight container for up to one week in the fridge or on the counter. You can also store this at room temp but if you want to pipe it, put it in the fridge for 30 minutes to let it firm up before using.Freezing: This icing will not freeze well because the marshmallow fluff may separate when thawed. I don't recommend freezing!
