Marshmallow Frosting

WANT TO SAVE THIS RECIPE?

Marshmallow frosting is one of those simple finishes that makes homemade desserts feel extra special. It is glossy, fluffy, sweet, and soft, with that nostalgic marshmallow flavor that instantly turns cupcakes, brownies, cookies, and cakes into something memorable.

What makes this marshmallow frosting especially useful is how quickly it comes together. You get a cloud-like texture that spreads beautifully, pipes well enough for casual decorating, and adds a light, creamy finish without feeling as heavy as some traditional buttercream recipes.

What Makes Marshmallow Frosting So Irresistible?

The magic of marshmallow frosting is in the texture. It is airy, smooth, and sweet with a soft vanilla finish that pairs with nearly any dessert. It feels playful and classic at the same time, which is why it works so well for birthday cakes, sheet cakes, sandwich cookies, and even warm brownies.

Another reason people love it is versatility. You can keep it simple for a quick topping, swirl it high for a dramatic finish, or toast it lightly for a campfire-inspired look. It is a frosting that feels easygoing but still brings plenty of personality to the dessert table.

Ingredients for the Marshmallow Frosting

• 1 cup unsalted butter, softened
• 2 cups marshmallow creme

How To Make the Marshmallow Frosting

Step 1: Soften the Butter

Place the softened butter in a large mixing bowl. Beat it for 2 to 3 minutes until it looks pale and creamy. This gives the frosting a smoother base and helps create that fluffy final texture.

Step 2: Add the Marshmallow Creme

Spoon in the marshmallow creme and mix until fully combined. Scrape down the sides of the bowl so the mixture stays even and smooth.

Step 3: Mix in the Sugar and Flavoring

Add the powdered sugar, vanilla extract, and salt. Start on low speed so the sugar does not puff out of the bowl, then increase to medium speed and beat until the frosting thickens.

Step 4: Adjust the Texture

If the frosting feels too thick, add heavy cream 1 tablespoon at a time until it reaches your preferred consistency. If it feels too soft, beat in a little more powdered sugar.

Step 5: Whip Until Light and Fluffy

Beat for another 1 to 2 minutes until the frosting looks airy and spreadable. Use it right away on cooled cupcakes, cakes, bars, or cookies.

Tips for Serving and Storing Marshmallow Frosting

Marshmallow frosting is best served the day it is made when the texture is at its softest and fluffiest. It works beautifully on chocolate cake, vanilla cupcakes, graham cracker bars, brownies, and sandwich cookies. For a fun finishing touch, you can toast the surface lightly with a kitchen torch after frosting.

If you need to store it, place it in an airtight container in the refrigerator for up to 3 days. Before using, let it sit at room temperature for 20 to 30 minutes, then whip it briefly to bring back its smooth texture. Frosted desserts should also be stored in a cool place so the frosting stays stable.

Frequently Asked Questions

Can I use marshmallows instead of marshmallow creme?

Marshmallow creme works best because it blends smoothly into the frosting. Melted marshmallows can become sticky and harder to work with.

Is marshmallow frosting the same as buttercream?

Not exactly. It has a lighter texture and a more distinct marshmallow flavor, though it still uses butter for richness and structure.

Can I pipe marshmallow frosting?

Yes, for simple swirls and soft piping. It is softer than stiff buttercream, so it is best for relaxed decorating rather than sharp, detailed shapes.

Does marshmallow frosting need refrigeration?

Yes, if you are not serving it the same day. Chilling helps keep the texture fresh and safe, especially in a warm kitchen.

What desserts go best with marshmallow frosting?

Chocolate cupcakes, devil’s food cake, vanilla sheet cake, brownies, cookie bars, and graham cracker-based desserts are all great matches.
