Marshmallow Buttercream is a remarkably light and fluffy frosting that is easy to make using only four simple ingredients. With its perfect level of sweetness, it is ideal for topping cakes and cupcakes, as well as filling sandwich cookies. For a classic buttercream recipe, try my American Buttercream Frosting.
Ingredients & Substitutions
Butter: Unsalted butter tends to be fresher and has a more consistent flavor when compared to salted butter, which can have varying amounts of salt depending on the brand.
Sugar: Confectioners’ sugar, also known as powdered sugar or icing sugar, is used in buttercream because it dissolves quickly and easily. Thus, it results in a creamy frosting like this one!
Almond Extract: Almond extract is a concentrate made from the bitter almond oil. A little bit goes a long way when it comes to adding a sweet, nutty flavor to recipes. If you don’t have any on hand, you can substitute vanilla extract. If you have a nut allergy you can also use Imitation Almond Extract which is typically not made with almonds. Be sure to check the ingredients.
Marshmallow Creme: Marshmallow creme, or marshmallow fluff, is a sweet and gooey spreadable concoction that tastes like marshmallows. Since this is a marshmallow buttercream, we can’t leave this out!
How to Use Marshmallow Buttercream
Marshmallow Buttercream is a delicious and versatile frosting that can be used to frost cakes, cupcakes, and other baked goods, as well as for filling sandwich cookies. Here are a few of my favorite ways to use it:
- Neapolitan Spritz Cookies
- Chocolate Cupcakes
- Perfect White Cake
- Peanut Butter Cookies
- Chocolate Chip Cookies
- Salted Caramel Brownie Marshmallow Hi-Hats

How to Store Marshmallow Buttercream
Store marshmallow buttercream in an airtight container in the refrigerator. It will last up to a week. When ready to enjoy, first, let the frosting come to room temperature before mixing it up to get it light and fluffy again. For longer storage, freeze for up to 2 months. Let it thaw in the refrigerator overnight before using.

Don’t miss this frosting in my Ginger Sandwich Cookies!
Sounds perfect for cookies. How is it once it sits/dries on cookies or cake?
Is it soft, stackable?
Instead of confectionery sugar I used granulated sugar with butter now it’s not mixing as smooth paste can anything be done with this, I don’t want to throw it away.
Going to have to try this buttercream frosting I decorate cakes always looking for new easy ideas

Can I omit the almond extract? I love buttercream frosting, but the marshmallow is brilliant!!
You can omit, but it will change the flavor. 🙂
This sounds delicious. I will try it.
I halved the recipe because I was just making a pan of brownies. After I creamed the butter and ed the almond extract the two cups of confectioners sugar it was a fine powder (no moisture). Is it supposed to be…seemed ok after I added the marshmallow cream but it is awfully thick.
If your frosting is too thick feel free to add some liquid to thin it out. 🙂
