Easy Marshmallow Buttercream Frosting Recipe

So this frosting. I’m just gonna say that’s it’s insanely delicious.  Not because I made it.

Well, maybe that. But because how did I not think of this sooner? And I didn’t Google it because I would like to go on believing I invented it. And Google is an inventors dream-killer.

But anyway it’s so super simple I can’t take it… it’s buttercream frosting recipe, with toasted melty marshmallows mixed right in.

Duh, right?

The marshmallows give it an insanely yummy flavor, but also a cool texture!  Like a cross between marshmallow and frosting, which obvi… it is. Of course, piped some on top of a vanilla cupcake and sprinkled Rice Krispie Cereal, because Rice Krispies are my love language.

But I could totally get down with this on a chocolate cupcake with graham cracker crumbs sprinkled on top. S’mores, FTW!

So let me show you…Toasted Marshmallow Buttercream Frosting…

How to Make Toasted Marshmallow Buttercream Frosting:

And toast them under the broiler for just about 45 seconds, until they look like this…

And beat the heck out of it!

Let it cool a bit before piping or spreading.  You’re gonna LOVE the texture of this frosting.

And it works perfect as a filling to a cake!

As it cools it will stiffen up, so don’t go adding a bunch more powdered sugar!

As soon as I put the marshmallows in it completely melted my buttercream and ruined it! Cant have fluffy buttercream with melted butter! Now it just looks like runny icing sugar. Going to try letting the marshmallows sit for a bit before mixing in next time.

What is the yield on this? Can it frost and fill a 9 inch layer cake?

This sounds incredible! I’m going to use it to make s’mores cupcakes. I’ve recently been introduced to Swiss meringue buttercream, and I love it. Do you think this would work with that too?

Mine came out incredibly sticky & difficult to manage, does anyone have any hints or tricks as to what went wrong and how to correct it next time I give this recipe a whirl? I’d like to stay away from adding more powdered sugar, as the recipe as written is already very sweet.

I made this frosting today and it’s delicious however once it cooled it has become so sticky and thick that it is impossible to pipe. I hade to empty the piping bag and make a sloppy icing mess with a knife instead. Any suggestions?

This is really yummy AND easy! I just had a slight problem. It nearly wrecked my kitchenAid hand mixer because the marshmallows stuck themselves right up the beaters and into the holes that hold the beaters as I beat. I would recommend using a stand mixer. Other than that, yum!

Hi. Can I color this frosting – using gel paste? If yes, at what stage (before OR after adding/mixing the marshmallows into the buttercream?).

Another question, is there a recommended temperature for broiling the marshmallows? As per your instructions above, just turn on the oven and put the marshmallows in..

THANKS A LOT! 🙂

I made this icing last night and oh my goodness it is so good! I love the crunchiness of the marshmallows and the light flavor of this icing. It’s hard not to eat it by the spoonful!
