Marshmallow Frosting is one of our favorite easy frostings when we want something sweet, fluffy, and fun for cupcakes. It has that creamy marshmallow flavor from Marshmallow Fluff, plus butter, powdered sugar, and vanilla to make it smooth and pipeable.
We love using this on chocolate cupcakes, vanilla cupcakes, s’mores desserts and birthday treats. It’s simple to mix together, easy to pipe, and gives any dessert that sweet marshmallow finish kids and adults love.
We’ve made this frosting countless times because it is fast, dependable, and uses ingredients we often have on hand. If you love this recipe, be sure to try Chocolate Buttercream Frosting, Cinnamon Cream Cheese Frosting, Vanilla Buttercream Frosting, and Sugar Cookie Frosting too.
Why you’ll love it + Why it works:
- Only Four Ingredients: This frosting comes together with simple ingredients you may already have in your kitchen.
- Ready in Minutes: It takes just a few minutes to mix up, making it perfect for busy baking days.
- Perfect for Piping: The texture is smooth and fluffy, making it great for decorating cupcakes and cakes.
- Balanced Sweetness: Butter helps balance the sweetness for a frosting that is rich without being overwhelming.
Marshmallow Frosting Ingredients
- Butter (½ cup, room temperature): Creates a rich, creamy base and helps give the frosting structure. Be sure the butter is softened so it mixes smoothly.
- Marshmallow Fluff (7 ounces): Adds the signature marshmallow flavor and creates the light, fluffy texture that makes this frosting so good.
- Powdered Sugar (1 cup): Sweetens the frosting while helping it hold its shape for spreading and piping.
- Vanilla Extract (1 teaspoon): Adds warm flavor and enhances the sweetness of the marshmallow.
How to Make Easy Marshmallow Frosting
COMBINE. Beat butter and powdered sugar until fluffy and well mixed. Mix in fluff and vanilla by hand and mix well.
PIPE. Add to a piping bag and pipe onto cupcakes.
Kristyn’s Recipe Tips
- Let the butter come fully to room temperature for the smoothest frosting.
- Sift the powdered sugar if it has lumps to ensure a silky texture.
- Avoid overmixing after adding the Marshmallow Fluff to help maintain a light, fluffy consistency.
- If the frosting feels too soft for piping, chill it for 15 to 20 minutes before decorating.
