This easy-to-make Fluffy Marshmallow Frosting is spreadable, pipe-able and all around glossy and gorgeous!
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 was amazing and came out great !!! I love the taste !!
Hello, can i make this icing and put it in sealed piping bag and use it after a few hrs?
I have a friend requested this icing for a DIY cake kit giveaways.
It sets up and might be hard to pipe after sitting in the bags.
Divine! I used to frost a dozen chocolate cupcakes and had lots leftover! I didn’t bother with a piping bag, but next time I will or make 2 dozen cupcakes. This is so delicious and in my opinion, way better than buttercream! Follow the instructions as written and you just can’t miss. I think it would be good in a layer cake with some crushed pineapple mixed in as a filling for the middle layer. Thanks for this wonderful recipe!
Hi,
How would this hold up in hot weather. I would like to make smore’s cupcakes for my son’s birthday in August. But I am thinking they’d be fine if we have something at home. I can keep them indoors. But if we end up having something outdoors, then how would the frosting do?
I think it will do fine as long as it’s not too humid!
Hi! Just came across this! If I use this for lemon meringue pie, I assume I don’t need to bake it, and I can just spread on the pie and torch it? Thanks!!!
You don’t need to bake this!
How long can this frosting be unrefrigerated?
Honestly I don’t refrigerate this frosting unless I am making it in advance! I prefer my buttercream at room temp!
This is a standard Swiss meringue.
No, it’s not. It is what you get before you add BUTTER to SMBC. THIS is marshmallow or merengue frosting…what my mother called 7 minute frosting.
What happens after 24 hours? Does it deflate? Or is it unsafe to eat?
IT will deflate a bit 🙂
Does this taste like marshmallows? 😉
It tastes like frosting more so than marshmallows, but it definitely has a subtle marshmallow flavor!
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 fridge in a cake saver. It held up very well.
