i am so sorry I wasted my butter and my marshmellow cream. I followed the directions and use marshmellow cream vs marshmellow frost (not available) the flavor was like eating a butter mess. I added more marshmellow cream and it is almost tolerable. i also ended up throwing away the entire mess.

I've search places for a jar of fluff.
So i was craving for this so i opted to buy some marshmallows and melt them in the microwave and add some powdered sugar. But by the moment thwy start to cool down they go back to its solid form. I'm asking friends to buy me a jar of fluff somewhere else. Huhu! :(

Sandy, I use marshmallow cream located by the marshmallows in the stores, if your store don't have it...there are a couple recipes for it on here. :o)
Also, I added at least 3 cups of powdered sugar maybe even 4 to get the right spreading consistency...maybe thats the difference between fluff verses cream. But I use the cream in anything that calls for fluff, because I can't get fluff around here. It don't make a difference in any other recipe though.........hope that helps you.
