Buttercream Frosting For Lazy Cheaters

... like me, of course.
You'll need:
- one 7 1/2 ounce jar of Marshmallow Fluff, and I realize that I've posted a lot of recipes using it, which is embarrassing, in a way.
- one cup softened butter.
- one cup of icing sugar. So obviously we're talking about a VERY HEALTHY recipe, right?
- some vanilla - about 1/2 tsp. - and food colouring, if you don't want ivory icing.

Using an electric mixer, beat the butter until it's fluffy and creamy and then add the whole jar of Marshmallow Fluff, which will be a sticky pain in the butt. Reduce speed and add the icing sugar, vanilla and food colouring and mix it all together. Now turn your mixer back up (and why do you do it this way? So you don't send icing sugar flying all over your kitchen. Learn from my mistakes.) and beat everything briskly until it's fluffy and gorgeous. There you go.
