Marshmallow Buttercream = Delicious.
It seems to me that people are either icing on or icing off kind of people. Are you an icing person? I like icing, but I really just prefer cake and cupcakes naked. Unless there is some kind of marshmallow involved (or that white icing you get on cakes in the grocery store…I don’t know what it is about that kind of icing but I love it). But a marshmallow frosting? Sign me up.
Add Marshmallow Fluff!
On the weekend I made chocolate cupcakes and was trying to decide what kind of frosting to ice them with. As I pulled out the recipe card for my tried and true vanilla buttercream I wondered what it would taste like with marshmallow added. Marshmallow makes everything delicious don’t you think? Well it certainly made this frosting ah-mazing.

Marshmallow Buttercream Recipe Tips
- How much frosting does this recipe make? This Marshmallow Vanilla Buttercream Frosting is the perfect icing for either chocolate or vanilla cupcakes! Will ice 12 – 16 cupcakes (thickly), or 24 cupcakes if spread more thin.
- The key is in the whipping! For the most fluffy, soft and creamy frosting, whip, whip, whip, making sure to scrape the sides of the bowl often!
- Marshmallow Fluff: This is also sometimes called Marshmallow Creme. You can find it in small plastic containers in the candy aisle (sometimes it’s also in the baking aisle). The containers are usually 198 g (7 oz) which is what I use.
- Butter: You can use salted or unsalted butter, at room temperature. If you use salted butter, you may not want to add any extra salt.
- Icing Sugar: Also called powdered or confectioners sugar.
- Flavour Tip: You can add 1/2 tsp vanilla to the frosting if you wish.
- What if my frosting is too soft/thin? Just add more powdered sugar, 1 tablespoon at a time.
- What if my frosting is too thick? Add more cream, 1 tsp at a time until it’s the consistency you want.
- Make Ahead: This frosting can be made ahead of time. Just store it in an airtight container in the fridge, then bring it up to room temperature before you use it.
- Storage: Keep any leftover frosting in an airtight container in the fridge.
- Do I need to keep my frosted cake/cupcakes in the fridge? This is a personal preference. I am comfortable leaving my frosted cakes/cupcakes out on the counter for up to 2 days. You can keep them in the fridge if you like.
- Will this frosting crust? It will crust like any other buttercream, if left uncovered, but honestly, I haven’t found this to be a problem.
- Can I add food colouring to the frosting? Absolutely. I like to add a bit of red to make pink cupcakes for Valentine’s Day.
- Frosting Tip: I used a Wilton 1M icing tip for the icing roses.
- Can I torch this frosting? NO. This is a buttercream base so it will just melt.

Thank you Jo-Anna for your reply to my question. I will definitely be using fresh puréed raspberries in your marshmallow buttercream icing recipe. Since I will be using this icing as the filling I want it to be thicker than a spreadable icing. This is going to taste sooo good with the rich, dark chocolate cake. 🙂
Just made this frosting for my sons snowman cupcakes. I’m not a buttercream fan so I can definitely taste the butter, but otherwise it is so good! It is a bit soft so Ill keep the cupcakes in the fridge till I’m ready to take them to my sons school. Great recipe!
Yay! That is awesome!!
Can you tell me who makes the marshmallow fluff used in this recipe? I live in UK. MY granddaughter loves marshmallow flavour so I really have to try this recipe.
Hi Glenda! I use the Kraft Marshmallow Fluff, but I’ve also used the brand Fluff. I hope you can find them!
Thank you so much for this awesome idea!!! My husband is a marshmallow fluff junky 😉 though its hard to find in a german grocery store, I know where to get it and its mostly unknown… I’ll make it my new favourite secret ❤️
You are so welcome! I hope you enjoy it! xo
This is definitely a hit and I’m not even a marshmallow fan. I decided to try this because I was making the cupcakes for kids and wanted to deter myself from snacking on the extras. That was a major fail because I have no self control and I like this icing better than the standard buttercream I can’t stay away from. My taste buds thank you for this recipe, however my waistline doesn’t.
Hahaha! I know what you mean…I have a weakness for icing too! I’m so happy you like the recipe though! xo
Hi, I’d like to try this frosting on the tops of s’mores cupcakes…do you think it would toast if I heated it gently with a torch?
Hi Shannon! No, this icing will not torch…because it’s a buttercream base it will just melt.
How many cupcakes will this frost?
Hi Peggy! This recipe will frost 12 – 16 cupcakes (thickly), or 24 cupcakes if spread more thin.
Can I use marshmallow cream instead?
This was exactly what I was imagining, and hoping to find. I took it to a dinner party tonight and wow what a success! This will also be one of my go-to recipes. It was messy and sticky to make but sooo worth it!
I’m so happy you like it Marilyn!
Thanks so much! I bought a grocery store pumpkin spice cupcake in the fall and it had a lovely, fluffy icing. Yours is the first recipe to replicate it. I am grateful you shared. Now to find a beautiful poured fondant icing. Happy Easter.
Oh that makes me so happy Nancy! Happy Easter to you!
