Found this recipe in a magazine awhile back. Very YUMMY!! Great to ice a cake with and do some simple decorations…such as borders, writting, scroll work; but it does not crust.

Marshmallow Creme Buttercream


  • 1lb (4sticks) of unsalted butter, softened
  • 2 jars or tubs (7 or 7 1/2 oz each) or 1 large tub (16 oz) marshmallow cream (such as Marshmallow Fluff or Creme)

  • 2 cups confectioners’ sugar

  • 2 tsp vanilla (I had to reduce to 1 tsp b/c the vanilla flavor was overpowering w/ 2 tsp) you could also sub another flavoring for the other tsp.


  1. Beat butter in a large bowl w/mixer on medim speed until creamy. Beat in marshmallow cream. When well blended, beat in confectioners’ sugar and vanilla. Increase speed to high and beat 3 to 4 min until fluffy.

I did it for S'more cupcakes but it didn't really taste like marshmallow, I used just one teaspoon of's delicious reminds me of the vanilla Swiss meringue buttercream.

I don't particularly like buttercream, but this is fabulous!!! I don't use anything else. I actually add 2-3 tsp of Wilton's clear vanilla and it is wonderful!

Does this crust? How does it do with decorations? Can it be used as filling?

I love this icing. You can't really taste the marshmallow, but it's fluffy and really nice to work with. I like how it's a big spongy. Thanks for sharing.

Anyone ever covered this with fondant?

I absolutely love this icing. I have been trying to find a buttercream that I really love for a while now and haven't been able to settle on one. I don't like the flavor of icing with crisco and am not a fan of the consistency of all-butter buttercream. So glad I found this!! The consistency is great and it doesn't have any sort of lingering unpleasant taste caused by shortening. The only thing I would complain about is the fact that the butter flavor gets stronger with time and becomes a bit overpowering in my opinion. I will definitely make this again in the future, but might play around a bit with the butter/marshmallow ratio to lessen the buttery flavor a bit.

And tjames30--I covered this with fondant and it worked great!

Oh my goodness! I've finally found a buttercream that I actually love, not just tolerate! IMHO, It seemed to get a little sweeter as it set, so if you'd like a not so sweet BC, use it right away. If you like it sweeter, make it a couple of days early. I covered it in Buttercream Flavored Marshmallow Fondant (recipe on CC) and it traveled over 4 hrs on some pretty rough roads. It does not crust, tho.

Since it doesn't crust, does it smooth well? I've made icings that don't crust and had them run down the side of a cake before...haha. Is it firm? I'd love to see a picture of how it looks on a cake...I wonder if adding meringue powder would make it crust??

The last sentence in her descriptions says that it will not crust.

I'd like to know the same

I come back with the same question, can anyone tell me if we can make borders or flowers, thank you

Has anyone tried adding to this frosting? Like chocolate or puréed fruit?

cooncat Says... 2015-05-11 20:15:20

You can make your own marshmallow crème with a prep time of about 10 - 15 minutes if you do not have the pre-made type.  Just type in homemade marshmallow crème in your search engine and there are several easy recipes with great ratings out there.

Can anyone tell me if it's possible to make flowers or borders with this buttercream, thank you

I made this and added an additional cup or so of powdered sugar because the flavor of the butter was so strong. It is very tasty, but I felt like it became very soft when brought back to room temp after being in the fridge overnight, so IMHO, I don't think it would be great for piping or flowers.  Maybe it would stiffen up if you added more powdered sugar.

Thank you newbiebaker 1 for your answer.
