Is there a recipe for marshmallow buttercream on here? I did a search for it, but nothing came up. I looked it up on goggle & heres a recipe I got: is this one good or should I just make regular buttercream & add marshmallow flavoring?

Ingredients
1 cup unsalted butter, softened
1 (7 1/2 ounce) jar marshmallow cream (such as Marshmallow Fluff or Creme)
1 cup confectioners' sugar
1/2 teaspoon vanilla extract

Directions
1Beat butter in a large bowl with mixer on high speed until creamy.
2Beat in marshmallow creme.
3Reduce speed to low, and beat in confectioners' sugar and vanilla.
4Increase spead to high; beat until fluffy.

Sorry I couldn't be of more assistance.

I wonder if you can add marshmallow creme to SMBC?

You should be able to add a little. I know that IMBC can only hold "extra" a certain amount of liquid added to the recipe before it will break down. I tried this with IMBC and Strawberries years ago and it turned out soupy.

Yeah, I made that mistake with raspberries once...it still tasted really good though!
