Easy Marshmallow Frosting
I first tried this frosting recipe when I made homemade oatmeal cream pies. After the first bite, I was hooked! It has the perfect consistency with amazing marshmallow fluff flavor. I could seriously eat it with a spoon!
This marshmallow frosting takes your classic buttercream frosting up a notch. The added marshmallow cream makes consistency super fluffy and delicious. It’s perfectly sweet and rich and makes a great compliment to so many desserts.
4 Ingredients
- Butter: Softened salted butter works best. If using unsalted, add 1/4 teaspoon salt for every stick of butter.
- Powdered sugar: This helps make it sweet and creamy. Add more or less powdered sugar depending on the type of consistency you want.
- Marshmallow creme: Also known as marshmallow fluff. You’ll need 1 jar.
- Vanilla extract: For an extra boost of flavor.
How to Make Marshmallow Frosting
- Combine. Add all of the ingredients to the bottom of a large mixing bowl.
- Mix. Using an electric mixer, whip mixture on medium speed until the consistency is smooth and fluffy.
- Store. Cover the marshmallow frosting and place in the fridge until ready to use.
Helpful Tips
- Consistency. To thin it out a little, mix in 1-2 Tablespoons of milk or heavy cream. Add more powdered sugar to thicken the frosting if needed.
- Adding to baked goods. If frosting cupcakes, consistency should be thick enough to hold a point. If frosting cookies, I prefer it thinner so that it can easily spread on top.
- How much frosting this will cover. This recipe makes enough to frost 12-15 cupcakes if using a piping tip. It will frost 24 cupcakes if you spread it on with a knife.
- Spread then add toppings: If adding on any extra toppings such as sprinkles, make sure to do it immediately after you frost your dessert so that it sticks.

FAQs
No, you need marshmallow fluff. Regular melted marshmallows do not contain the additional corn syrup and egg whites like fluff does and would not mix in well with the frosting.
You can keep it out at room temperature on the counter for about a day, then it will need to be refrigerated. I like to refrigerate it if I am going to pipe it. Bring to room temperature before using.
You can store this marshmallow buttercream frosting covered in an airtight container in the refrigerator for up to 7 days. I wouldn’t freeze the frosting as the texture from the marshmallow fluff will change when thawing.

Does it harden at all? I plan to put it on cookies, and I wanna know if I could stack them.
This is more of a softer frosting, so I’m not sure they’d stack as well.
Very good and easy to make.
