Marshmallow Buttercream Frosting with Marshmallows- Creamy buttercream frosting made with real marshmallows..no fluff required! It’s the perfect topping for your favorite cupcakes or cake.
Fun fact: I stink at spelling. If it wasn’t for spell check ( and my husband), my blogs would be a mess of all kinds of grammatical errors.
For example: One of my early posts over at Table for Seven included marshmallows. I kid you not, I spelled marshmallow wrong in the title of the post. That’s not the sad part. I didn’t even realize it until about a year later, when I was correcting something else that was in the post. 😳
I have gotten better. OK, not really. But, my husband edits all my posts now and will catch stuff before it goes public or really soon after. 😉
Speaking of marshmallows, there are some in this frosting and it’s fabulous.
Why do I specify there are marshmallows in a marshmallow buttercream frosting? Many of the marshmallow buttercream frosting recipes online call for marshmallow fluff/creme. Not this one. We are using actual marshmallows.
- Butter Flavored Shortening
- Powdered Sugar
Marshmallows: I used 2 cups of large marshmallows, because, honestly, it is what I had on hand. Mini marshmallows will also work.
Butter Flavored Shortening: I like to use Crisco butter flavored baking sticks in my frosting. Regular shortening will also work.

How to Make
- First, melt your marshmallows with the milk. I like to do this in a saucepan over medium heat. However, you can do this in the microwave. If you use the microwave, melt them in 30 second intervals. This will help prevent burning. If you do choose the stove top method, stir those marshmallows frequently! Again, prevent burning.
- Let them sit for 5-10 minutes to cool.
- While they are cooling, beat the butter and shortening. Make sure they are room temperature. This helps give the frosting it’s creamy texture.
- Then, add in melted marshmallow and vanilla. Beat it well.
- Gradually, add in your powdered sugar. Adding it gradually will be easier for you to check the consistency of the frosting. Plus, it’s much less messy. Start with 2 cups and if needed, add 1/2 cup gradually until the frosting has reached your desired consistency.
- Keep your leftover frosting in the refrigerator in a covered container. When you use your leftover frosting, let it come to room temperature before using. It will stay good in the fridge for about 2 weeks.

What a great idea! I needed a filling for a Swiss cake roll type cake and I think the marshmallow will give it the right texture, taste, and be a little more sturdy than your average buttercream when chilled. I made a half recipe with plant butter but doubled the marshmallows and it turned out perfectly.

Hi Grace- Yes it can be used in a filling for the cookies and yes, you can put it in the freezer. Just be sure to store it in an air tight covered container/storage bag.

Could you sub all butter instead of butter crisco, as in buttercream frosting or would it be too soft? The crisco is a little more stiff than butter, though I love both! Thanks!

Hi Luci! You could, but, the consistency may be softer.

I have never commented on a recipe blog before, but I wanted to let you know how much I appreciate this recipe! I thought about a marshmallow icing for a birthday cake because I had accidentally received a double order of two sizes of marshmallows... so I have a lot on hand! Like you said, most recipes don't call for actual marshmallows. So thank you!
