The FLUFFIEST Marshmallow Frosting

Fluffy Marshmallow Frosting Is Sweet, Light, and GORGEOUS!

I love frosting so much and since I’ve got the basics here on my site for you (Perfect Buttercream and Creamy Chocolate Frosting). We now get to move on to the FUN STUFF!!

This marshmallow frosting is fluffy, creamy, glossy, sweet but not too sweet, spreadable, pipe-able and an ALL AROUND WINNER.

What Actually IS Marshmallow Frosting?

This is the frosting for those of you who (gasp) aren’t into buttercream. It’s such a beautiful frosting and it’s easy to make. It also happens to be much lower in fat and calories than buttercream, if you’re worried about that kind of thing.

It starts with an egg white base. You heat the egg whites so there is no danger of salmonella. You whip them up with granulated sugar, cream of tartar (to stabilize the egg whites), a pinch of salt, and a little vanilla extract.

You whip it for 7-9 minutes, so a stand mixer works best, but you can absolutely do it with a hand mixer… but you want the peaks to be stiff and glossy.

The only down-side to this frosting is it doesn’t really keep for very long. I always recommend serving the same day. BUT if you have to store it, airtight in the refrigerator for up to 24 hours max.

It pipes like a DREAM…

And it toasts up so pretty using a kitchen torch.

You can absolutely spread this on a cake, but it isn’t great for FILLING a cake, because it is so soft in texture. It’s best for covering cakes, and piping onto cupcakes.

Dreamy, isn’t it?

This easy-to-make Fluffy Marshmallow Frosting is spreadable, pipe-able and all around glossy and gorgeous!


Ingredients:

  • 4 large egg whites
  • 1 cu granulated sugar
  • 1/4 teaspoon cream of tartar
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla

Instructions

  1. Add the egg whites, granulated sugar, cream of tarter, and salt to a heat-safe bowl of an stand mixer. Set the bowl over a saucepan filled with a few inches of simmering water.
  2. If you aren’t using a stand mixer, use any large heat-safe bowl, with high sides for mixing.
  3. Heat the mixture, whisking constantly until the egg whites are warm to the touch and sugar has dissolved, about 3 – 4 minutes.
  4. Remove the bowl from the heat and transfer to your stand mixer fitted with the whisk attachment. Mix on high speed, until stiff, glossy peaks form, about 7-9 minutes. Add the vanilla during the last 10 seconds of mixing.
  5. Spread or pipe onto cake immediately.

Notes:

Best if used immediately.

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts.

First of all, this was amazing. We didn’t end up using it all to cover the cake (which was a little more than two tiers, to give you an idea) so we just ate the rest of it ourselves because it was too good. I wasn’t able to find any comments before I made it about how long it actually lasts, so I wanted to share that I made it on a Tuesday and finished it on a Friday. The marshmallow had started to lose its shape but it wasn’t falling off or separating. I also stored it in the… Read more »

First time making a marshmallow frosting and it came out great! Consistency was perfect. Frosted chocolate cake and refrigerated it until we ate it in the evening.

Do you think I could use meringue powder instead of the egg whites? How would you recommend making that swap?

Will adding less sugar (half as much) prevent the whites from getting thick and forming any peaks at all?
