Add swirls of this creamy Marshmallow Buttercream Frosting to your cupcakes or cookies. This homemade buttercream frosting is made in minutes with just a few ingredients. It’s sure to get smiles from everyone when they taste it.
Do you have a certain style when it comes to how you bake and cook? There are those who make everything from scratch just like their grandma did before them. Those people have my utmost respect because that’s an amazing talent.
Then there is the type of person that likes to utilize baking mixes from the store. That’s totally me.
I like to describe my baking and cooking style as semi-homemade. Give me a box mix and I’ll show you how to jazz it up, so it looks like it came from a bakery and not your kitchen.
Now the exception to that is when I make frosting. I do believe in making homemade frosting because it tastes 100 times better than the one from the can.
Now don’t get me wrong. Store bought frosting has its place. It’s great to use in a pinch when you don’t have time to whip up frosting. Or for dipping graham crackers in when you need to satisfy your sweet tooth late at night.
But when it comes to cakes and cupcakes, I like to make homemade frosting. It’s one of the things that makes a box cake mix taste like they came from the bakery.

- Softened Butter
- Marshmallow Fluff
- Vanilla Extract

- Powdered Sugar
This Marshmallow Buttercream Frosting is so creamy and tastes just like the inside of a ding dong. It’s gooey, delicious, and perfect for adding to these S’mores Frappuccino Cupcakes or these S’mores Sugar Cookie Bars.
How to make Marshmallow Buttercream Frosting:
Beat the butter and marshmallow fluff until it is creamy. Add the vanilla and salt and mix again.
Slowly add the powdered sugar and heavy cream until it is all mixed in.Beat the frosting for an additional few minutes until it is light and fluffy.
Fill piping bags fitted with an icing tip and swirl it on cupcakes or cookies, or spread it on top of cookie bars or brownies.
How much frosting do you need?
That will depend on what you are frosting and how thick or thin you spread your frosting. This recipe will give you enough frosting to frost 24 cupcakes or an 8 inch layer cake. Use half a batch of frosting if you are spreading it on cookie bars, brownies, or a 9×13 cake.
Can I use marshmallows in place of the fluff?
Yes, you can. You will need 16 large marshmallows or 2 cups mini marshmallow plus 2 Tablespoons of corn syrup. Place these in a microwave safe bowl and heat for 45 seconds. Let the mixture sit for a minute, then stir until creamy.
Let the marshmallow cream cool for at least 5 minutes before adding it to the frosting. Do not add it if it is still hot or warm, as this will cause your buttercream to separate and be runny.
Does marshmallow buttercream frosting need to be refrigerated?
This frosting can be stored at room temperature for a few days. If it will be longer than 2-3 days, refrigerate your baked goods in a tightly sealed container.
Can buttercream frosting be made ahead of time?
If you want to make your frosting ahead of time, store it in a tightly sealed container in the refrigerator. Before using, bring it to room temperature and then mix it with your hand or stand mixer.
