Simple Marshmallow Fluff Frosting Recipe (No Butter)

Ingredients:
- 1 jar (about 7 oz) marshmallow fluff or marshmallow creme
- 1½ cups powdered sugar
- 1-2 tablespoons milk (any kind or dairy-free alternative)
- 1 teaspoon vanilla extract
- Pinch of salt (optional, for balance)
Instructions:
- In a large bowl, add the marshmallow fluff.
- Slowly beat in the powdered sugar, ½ cup at a time, using a hand mixer or stand mixer.
- Add the vanilla extract and a pinch of salt.
- Add 1 tablespoon of milk and beat the mixture on medium-high speed for 2-3 minutes until light, smooth, and fluffy. If it’s too thick, add the second tablespoon of milk gradually.
- Use immediately to frost cupcakes, cakes, or cookies.
Tip: If you’re piping, chill the frosting in the fridge for 10-15 minutes to firm it up slightly for cleaner designs.
How Long Will Marshmallow Fluff Frosting Last?
- At room temperature: Up to 4 hours (ideal for immediate use)

- Almond Extract: Swap out vanilla for almond extract for a nutty flavor profile.
