Hey there! Before you scroll, there’s lot’s of important stuff in the post!…including the FAQ section, which may answer any questions you might have about this recipe. Enjoy!
There isn’t much that I love more than crackin’ open a jar of marshmallow creme and digging straight into it with a spoon. Ok, it does get better when you add peanut butter to it, but that’s not what we’re doing today.
Anyway, my point is I’m totally fine just eating marshmallow fluff out of the jar, but you can’t just throw some marshmallow fluff onto a cake and it work out. I mean I guess you could, but I feel like it just needs a little somethin’.
LET’S TALK ABOUT SOME OF THE INGREDIENTS IN THE FLUFFY MARSHMALLOW FROSTING:
Cream cheese: This helps to give the frosting some stability and it adds to the taste by cutting the sweetness of the marshmallow fluff and confectioner’s sugar.
Marshmallow fluff: Of course marshmallow frosting needs marshmallow fluff…it’s also called marshmallow cream. I don’t know of an alternative to this. Using melted marshmallows won’t give you the same results.
Butter: Butter makes everything better, right? Well it’s in this recipe to give flavor, creaminess and stability.
Confectioners Sugar: This is what will give it some sweetness.
MIXING METHOD FOR THE MARSHMALLOW FROSTING:
The mixing method for this frosting is super straight forward. You’ll essentially just whip it all up until it’s all super light and fluffy.
I added this frosting to my pineapple coconut cake, but it would also taste amazing on some chocolate cupcakes. (And I will be the first to admit that I don’t even need to put it on anything but a spoon.)
TIPS & FAQs FOR MAKING THE FLUFFY MARSHMALLOW FROSTING:
- Yes, you do want to actually add in the cream cheese. They tanginess cuts the sweetness a bit. The same goes for the salt.
- What is the difference between marshmallow creme and marshmallow fluff? I don’t think there’s any difference at all. I use the two terms interchangeably. Marshmallow creme does sounds fancier though, right?
- Try to get your cream cheese and butter close to room temperature, so they’ll mix together better.
- If you don’t have vanilla bean paste, not big deal, you can use vanilla extract.
- This recipe will not make a ton of frosting. It’s a really sweet frosting, so you won’t want to add a ton to your cupcakes or your cake. It makes the perfect amount to cover around 2 dozen cupcakes, or a two layer, 8″ cake that is filled with a different filling.
- If you’ll be using this to frost the outside of the cake AND as the filling between the layers, you may want to double the recipe.

This frosting is delicious. I think it tastes like cream cheese more than marshmallow, but I’m fine with that! I made it for “s’mores cupcakes” for my daughter’s backyard camping birthday party with chocolate batter and teddy grahams as a garnish. Will DEFINITELY make this frosting again!
Kara Jane
Hi Justine! So glad you like it! I had a lot of trouble getting myself to stop eating this straight out of the bowl when I made it. 😂 Thanks for the great review and the s’mores cupcakes sound wonderful!
Jackie Gibson
I was thinking of using this only as the filling between the layers. Thoughts? Would buttercream or cream cheese frosting be best for the cake itself?
Kara Jane
Hi Jackie, Oh yes I think it would work just fine as the filling. I’d do a thicker icing dam around the layers, or just don’t add a hugely thick layer of the marshmallow filling. It’s a little lighter and might squish out if you make it too thick or if the cake is too heavy. I think the frosting on the outside of the cake would depend on the type of cake you’re making. So, if it’s chocolate, I’d probably just do a chocolate buttercream on the outside. If it’s an apple cake, pumpkin cake, spice cake, red velvet, strawberry…then I’d do the cream cheese. If it’s vanilla, I’d do a vanilla buttercream and even add a little fruit in it if you wanted. I hope that helps!
Veronica
Does the icing become like a marshmallow once on the cake?
Kara Jane
No, not really, it stays as a buttercream consistency.
Becky
First – this was really good. Only had a 7 ounce jar of fluff on hand, so made a half batch. It was still a lot of frosting and more than enough to put a thick layer on a 9×13 pan. Yum.
Kara Jane
Hi Becky, I’m so glad you liked it! Thanks for the great review! 💖
Maria
How long can this be made beforehand? Does it need to be refrigerated? Could you add cocoa to make it chocolate?
Kara Jane
Yes you could add cocoa powder to it if you’d like. And yes, you should store this in the fridge because it contains cream cheese. This buttercream should be good up to a week, so you could make it a couple days beforehand if you needed to. When you get ready to use it, you can re-whip it if you want.
Cheryl
Is this pipeable?
Kara Jane
Well you could probably pipe your average cake borders with it, but it wouldn’t work well piping intricate designs or flowers really. It’s on the soft side.
