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:

Just mix up a basic buttercream.  You’re gonna go a little lighter on the sugar because the marshmallows add sweetness.

Then spread marshmallows on a parchment lined baking sheet…

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

Immediately mix that right into the frosting.

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!
