This creamy, delicious marshmallow frosting has 4 ingredients, is loaded with marshmallow creme/marshmallow fluff and only takes a few minutes to whip up.
In large mixing bowl, add the butter, marshmallow fluff and vanilla extract. Using a hand mixer, beat on medium speed until light and fluffy.
Gradually add in powdered sugar and beat until well combined. If the frosting consistency is too thick, you can add 1 tablespoon of milk at a time to reach your desired piping consistency.
Spread the frosting or place in a disposable piping bag fitted with a large tip to pipe on a cake/cupcake/bar/cookie.
Store in an airtight container at room temperature for up to 3 days or in the fridge for up a week.
