Marshmallow Buttercream Frosting Recipe
This marshmallow buttercream frosting is rich, sweet, smooth, and soft. It’s essential in my three-layer Smores Cake and is used between the layers, around the the cake, and helps the marshmallows I pile on top to adhere better. It is a perfect piping frosting because it’s neither so dense you can’t spread it, nor so thin that it refuses to stay where you put it. It’s wonderful on top of cupcakes, brownies, or just smear it between a couple of graham crackers when you’re craving a midnight snack. Best of all, it’s a cinch to make and literally is a five-minute recipe made with just five ingredients — the best kind!
Ingredients In Marshmallow Buttercream
For this five-ingredient marshmallow fluff frosting, you’ll need the following ingredients:
Butter: This is the base and structure of this buttercream frosting. Powdered sugar: This not only sweetens this frosting but it aids in the structure of it. Marshmallow Fluff or Marshmallow Creme: This is what will give the buttercream its marshmallow flavor. Vanilla Extract: Classic marshmallow flavor is made with vanilla so adding it to this buttercream will help enhance the flavor that the marshmallow fluff brings. Salt: As with everything else, salt brings out all of the flavors present and gives balance to prevent an overly sweet taste.

Ways to Use Marshmallow Frosting
Apart from using it in my Smores Cake, it would be be perfect on a basic yet divine Chocolate Cake, in between the layers of my three-layer Triple Chocolate Cake, or to give almost a Twinkie-esque vibe to my Yellow Cake. Even more desserts to pair with this homemade marshmallow buttercream frosting include:
Fudgy Frosted Brownies White Chocolate Blondies Frosted Double Chocolate Cookies White Cake Cookies and Cream Cake
Storage Instructions
Frosting may be stored airtight in the fridge for up to 1 month.
Can Marshmallow Frosting Be Frozen?
Yes, I imagine so. I think it’d deflate somewhat once frozen, so you may need to re-whip the frosting for a minute or two prior to serving it.
Tips For the Best Marshmallow Frosting
The marshmallow fluff icing will come together long before the 4 minutes I call to beat the frosting in the recipe. However, I advise you to continue mixing because it allows the confectioners’ sugar to melt into the butter. Additionally, it allows air to be whipped into the frosting which gives it a better consistency due to enhanced volume, making it more ideal for piping or frosting. While a stand mixer is not essential for making buttercream frosting, if you have one, now is the time to put it to use. If not, use a hand mixer noting you may need to beat the frosting a bit longer.
