Homemade Marshmallow Frosting recipe - yum! Few ingredients including marshmallow fluff, butter, vanilla, & powdered sugar make this a hit!

Hey there friends!!

Today I’m participating with some blog buddies in The Pinterest Challenge.

If you’re wondering what that is, it’s a group of awesome bloggers who create projects they’ve actually pinned. I’m their guest “Pinhead” of the month, and I’m excited to share with you the recipe I did.


Well, last week I shared the Free Transformers Cupcake Toppers with ya that I made for my nephew’s birthday party. Along with the toppers I obviously made cupcakes but wanted to change things up a bit. I decided I wanted to use Marshmallow Frosting. Β I did a few google searches but found only ones that involved egg whites and decided I needed a quick and Easy Marshmallow Frosting. I had remembered I saw one on Pinterest one day. It was from Just a Pinch. I usually modify all recipes, but this one I just added a little vanilla because I didn’t want to mess anything up. πŸ™‚

Here is how you can make it too…

Oh, I love marshmallow frosting!!! I’ve seen recipes for marshmallow frosting before, but they had eggs in it. I love your egg free recipe. So easy! Thanks for sharing! πŸ˜€ Hope you have a great day! πŸ˜€


    Lil' Luna

    Thanks, Stephanie!! It really is so simple and so yummy, and I’m all about simple and yummy. πŸ˜€


    Rice mellow cream has no eggs. It’s in the gluten free aisle.


    Making this Delish recipe right now ! I saw some people mentioned eggs in or not . I am looking at a plastic 16oz container of Marshmallow Fluff now. Ingredients state..Corn syrup-Sugar-Dried Egg White-Vanillin.. Underneath says:Contains Egg. Hope this helps πŸ™‚


Is there a difference in the Marshmallow Creme and the Marshmallow Fluff? Where do you get the Fluff?


    you get the fluff in the same isle as like peanut butter and jam/jelly and that kind of stuff.:)


    It’s a regional thing. CrΓ¨me is more Western; Fluff is available in East and South. TExtures differ, but I’ve never seen Fluff so all I can say it that my friends who have seen both say that it’s lighter and fluffier, while crΓ¨me is denser and stickier.

Russell van Kraayenburg

That is easy! I love it. I’ll have to try it sometime soon!


hi, love your site! how many cupcakes will this frost?


this frosting is delicious! i may or may not have eaten the leftovers by the spoonful i the middle of the night….. its like marshmallowy but whippy and buttery and wonderful! my new favorite frosting πŸ™‚ i love your site!


Will this recipie toast up or turn slightly brown if flame is applied? I love the look of toasted marshmallow frosting.


Hi! I will definitely try this, sounds great! Just one comment regarding the “no eggs policy” here…. I’ve never actually seen a jar of marshmallow fluff, but I’m pretty sure it contains egg whites. That is why other recipes tell you to use eggs – because with those recipes, you basically make the marshmallow fluff from scratch. Just saying, in case some of you want to avoid eggs for medical reasons.


Marshmellow Fluff has egg in it!


Mine came out really wet. No way this could stand up on a cupcake. I even added a second container of fluff. It was still very wet and runny. Not happy!


    Mine did the same thing… Maybe I used creme instead of fluff? If there is a difference… Mine was more like a glaze but still yummy


Mine came out really REALLY thick and sticky and it was really hard to spread. What happened?


Hi there! I Thanks for the recipe, it was very easy to make. I just made it but I’m not sure if it came out right. It looks good, but it tastes like only butter and it’s kind of disgusting. Would I be ok to add more fluff or would it not change the flavor?


    Mine tasted like just butter and the consistency is very buttery. I tried adding more powdered sugar and some milk. It helped a little but I didn’t think it tasted like marshmallow at all. I loved how it spread though, it was very easy to decorate with.

      Lil' Luna

      So sorry you had a problem with this. Next time I would add more marshmallow fluff to see if that helps. πŸ™‚


Has anyone tried this with less butter! A cup seems like a lot. Looks delicious, though!

Shonie Castaneda

Can you bake a cake ahead of time, ice it with the Easy Marshmallow Frosting, then freeze it? If so, if you color the icing(to decorate), will it bleed after taking it out of the freezer?

    Lil' Luna

    You know what… Unfortunately, I couldn’t tell ya. I have never tried it. If you do end up trying it, let me know how it goes so I can know for the future. Good luck!

Susan T.

I wonder if this is similar to a recipe I have that contains Cream Cheese mixed with Marshamellow Fluff. I haven’t made it in a long time but it was great as a fruit dip at parties.

    Lil' Luna

    Ooooh, that sounds delicious to me!! I will have to give that a try next time I make Fruit Dip. πŸ™‚


Can you add food coloring?

    Lil' Luna

    Yes, you can! I would just make sure you don’t add too much so it the frosting stays a more thick consistency. πŸ™‚


Mine came out great! Fantastic! For those that said theirs came out runny, you didn’t something wrong. Check your ingredients and measurements again. Make sure you are using fluff.

    Lil' Luna

    Thanks, Shai! So glad yours turned out. We love it too and will be making it again today. πŸ™‚


Sorry phone typo… Not didnt*** you did do something wrong


This is really good and really easy. Those who are saying that it is runny are definitely doing something wrong, and if it’s too thick try mixing it some more. My 14 year old daughter made it with no problem!

    Lil' Luna

    Thanks, Sam! Glad it worked for you. I’ve never had a problem either and glad your 14 year old was able to make it. πŸ™‚


Well hello there πŸ™‚ I would like to know how long my this be stored for ?

    Lil' Luna

    I’ve actually never tried storing it and have made it right before using it. I’d imagine it would be good in a closed container in the fridge for at least a week or two.



Thanks for the great recipe! I’m wondering if you meant to say a HALF cup of butter? It tasted like straight butter, so I kept adding sugar and fluff and eventually milk, but nothing could make it taste better. Am I the only one who thought it was so buttery? It looked so good, and I wanted to like it. Any advice?


    I used half butter and half Crisco to cut down on sweetness and make it stand up better for outdoor wedding . Also added a little less marshmallow. It came out great!! This may solve some of the problems people have experienced

      Lil' Luna

      Thanks for sharing that info!! Also, thank you for trying this recipe!!


How many cupcakes can you frost with it?

    Lil' Luna

    I was able to frost about 1 dozen when I piped it on. It could probably frost 2 dozen if you just spread it on with a knife. πŸ™‚

Ammie Ortiz

Thank you SO MUCH, I’ve been looking for a recipe and this is PERFECT!!!! THANKS!

    Lil' Luna

    No problem! Thanks for stopping by. πŸ™‚


      Can I add flavorings like lemon juice? Thanks

        Lil' Luna

        Sure you can! I haven’t tried, since I love how it is, but that is a great idea! Let me know what you think!


Do you use unsalted butter?

    Lil' Luna

    I try to use unsalted butter in all my desserts, but will use salted if it’s the only thing I have on hand. πŸ™‚


Is this also good on a very humid day. I know I will love this. I am a marshmallow freak!

    Lil' Luna

    Unfortunately, I’ve never tried making it on a humid day. :/ I’d imagine it would be okay but may need a bit more powdered sugar to make it more stiff. πŸ™‚


Can you make this with dairy free “butter”? We use Earth Balance because my son is allergic to dairy and I’m trying to find a dairy free icing recipe that actually tastes good.

    Lil' Luna

    Unfortunately, I’ve never tried. If you do give it a try let me know how it goes so I can let others know. πŸ™‚


I made this marshmallow icing according to the instructions with 1 cup of butter despite thinking it was way too much butter and unfortunately it was. The icing was not very good. I checked some other marshmallow recipies such as Kraft and they call for 1/4 cup of butter instead. Perhaps it is a misprint.


Kristyn this marshmallow frosting is awesome, I’ll definitely make it again !!!! I used it for brownies I wanted to decorate with Peeps & jelly beans for Easter and I don’t like sweet frosting and never frost my brownies. This worked out great and is very easy to make, not saving the other recipes I found that would take a bit more time.


Does this frosting need to be refrigerated? I made a double batch and have a little left over. I want to frost more cupcakes tomorrow and am wondering. I love this frosting! I’ve used it twice now with great results. I used Creme one time and Fluff one time, and both worked great. A 10-year old girl at my daughter’s party today loved the frosting so much she asked if she could have another cupcake. πŸ™‚


I also was wondering if it should be refrigerated. It oozed slowly down the sides of my cupcakes.


how much does this make?

Kathy @ Living A Creative Life

This is my new ‘favorite’ frosting. Thanks so much for sharing!
I had a large container of marshmallow fluff and added much more than 7 oz., I think. So delicious!


I want to make this frosting for my sons Bay Max bday cake. If I only have marshmallow creme would you recommend adding a egg white or two or does the creme work out okay?


Silly me 😜 I didn’t look at the dates of these Posts !! OOPPS πŸ˜„ No matter what year it is, I LOVE THIS ICING !!


Can this frosting be toasted with a kitchen torch? I’d like to use this recipe for my s’mores cupcake frosting.

    Lil' Luna

    That’s a good question?? I haven’t tried, but I’d love to know!! Let me know how it comes out, if you give it a try!


This recipe is awful. I made it exactly as written, piped it onto cupcakes that I had made the day before, and the icing immediately began to melt. It didn’t hold the piping details at all, and ended up being an very unattractive “blob” on the cupcakes. The final texture is perfectly fine, but you the you’re going to make pretty cupcakes with this recipe, think again.

    Lil' Luna

    Sorry it didn’t turn out. I haven’t had that happen, so not sure what went wrong.


      For folks who are having it turn out floppy/drippy and not a solid shape holding frosting — you need to whip the butter/sugar until it’s fluffy. Can take a while. Then, FOLD IN the marshmallow FLUFF. If you continue to whip/beater-mix it will soften the fluff and ruin the texture. It might seem tough to hand mix/fold in the fluff, but do it little by little and this frosting turns out great.

        Lil' Luna

        Thank you for sharing that AJ!! Hope that helps anyone out there πŸ™‚


Question, Does the recipe call for 17 oz of Fluff? Or 1, 7oz. Jar of Fluff?


Does the recipe call for 7 or 17 oz of Fluff? It is very hard to tell.


The frosting turned out sticky and hard to work with. I followed every step to a T, but still was not pleased.

    Lil' Luna

    I’m sorry to hear that. I can’t think of why that would have happened? Thank you for trying it!

Deborah Sparks

Ive made quite a lot of frosting and really didnt think I would have issue because alot of people here did well with it. Mine piped well, but ran down the length of the cupcake in a matter of 10 minutes. I used 1/2 c of butter as recipe called for. Thoroughly whipped the butter/ powdered sugar with a stand mixer till fluffy. I did use marshmallow creme instead of fluff (as this is whats available here) so maybe that makes all the difference. I dont know. I will say while it tasted good, DO NOT MAKE this with Marshmallow Creme, it will run like a horse at the derby. ;0) . That is the only issue I can find to be at fault. Sorry.

    Lil' Luna

    No worries..thank you for sharing!! I’m sorry it ran down. That could be it or maybe heat/humidity?? Not sure where you are at. But, thank you for trying them!
