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.


    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.
