This may be a stupid question, but, what is Marshmallow Fluff and where do you buy it? Thanks.

i believe its the Jet Puff marshmellow cream. I get it at any grocery store and Smart N Final.

It's just creamy marshmallow stuff in a jar. Kind of like melted marshmallows in a jar. I just get in at our local grocery store in the baking aisle.

It can be found near the ice cream section or baking section in most grocery stores.

In our grocery stores it's by the peanut butter and jelly. It's famous for putting on sandwiches with PB. ("Fluffernutter" sandwiches)

It is a very important ingredient in recreating hostess filling

It is a marshmallow creme as everyone else has said, but it is also the most convenient type of marshmallow you can use for vegetarians.
