A Tip: When you are working with the marshmallow fluff, non stick cooking spray is your best friend! Spray your spoon, knife, frosting tool, etc with non stick cooking spray beforehand. This will make using the fluff a whole bunch easier.

I have a recipe for brownies that uses marshmallow fluff. I find that if you put dollops of the fluff all over the cake while it is hot/warm, the fluff softens up and is much easier to spread than waiting until the cake/brownie is cool. Just a thought to help others make this luscious dessert.
