Marshmallow Fluff Frosting

Marshmallow Fluff Frosting is light, silky, and irresistible. The cloud-like frosting combines smooth butter with gooey marshmallow creme to create a fluffy frosting that’s ideal for cakes, cupcakes, cookies—or honestly, eating straight from the bowl.

This recipe uses simple ingredients like butter, powdered sugar, and marshmallow creme (AKA: fluff). Just easy-to-find stuff you might already have in your pantry.

Additionally, this recipe is easy to make, and it makes a lot. Enough for a layered cake, or 30+ cupcakes.

Making Marshmallow Fluff Frosting

First, cream the butter. In a large mixing bowl (stand mixer recommended), beat the softened butter on medium-high speed for 2–3 minutes, until light and fluffy.

Next, in a small bowl, mix together the heavy cream and vanilla.

Then, with the beaters on LOW, add the powdered sugar and heavy cream mixture in alternating batches, starting and ending with the powdered sugar.

Once combined, beat on MEDIUM-HIGH speed until very fluffy.

If you want to add some meringue powder, now would be the time. Meringue powder helps to add structure to the frosting so it can hold the shape when piping. If you plan on spreading the frosting on, or using your ice cream scoop, skip the meringue powder.

Ok then, last part, add the marshmallow creme. Let the beaters mix everything, but then don’t over mix it; you just want it combined.

Since this recipe makes a lot, you can use a lot. I tried using my ice cream scoop on these Easy Chocolate Cupcakes, and I love how they turned out. I also used a cheese grater to grate the chocolate right onto the frosting. Easy peasy and oh, so delicious.

What can I use this new frosting on?

Well, I’m glad you asked; there’s a lot. Definitely on a multi-layered cake or cupcakes, but perfect on so many things. Spread it, pipe it, or try the ice cream scooper on cupcakes. Here are just a few other ideas.

Try this frosting on Homemade Funfetti Cupcakes, smooshed between two Maple Pumpkin Cookies, or serve an ice cream scoop on the side with your German Apple Cheesecake. So good!

This frosting is also good for dipping fruit in, adding to your bowl of ice cream, or putting on top of your pancakes and/or waffles. What a way to start your day — all smiles.

Basically, if you’re a fan of soft, fluffy frosting with a hint of marshmallow magic, this large batch of Marshmallow Fluff Frosting is your dream come true. It’s fast, delicious, and ultra-versatile for every sweet occasion.
