I originally found this idea over on exPress-o and decided to try it out myself. It offers a nice variation from the typical hot cocoa and/or coffee options. I like to call it "Creamy Milk" (original, I know).
Fill a mug with milk (I use non-fat) and heat in microwave until hot. Add a few splashes of your favorite coffee creamer (I prefer sugar-free Lucerne vanilla creamer) and top with whip cream/cinnamon/whatever you feel like.
It ends up tasting kind of like white chocolate hot cocoa. At first I was a little skeptical (I'm not a big fan of hot milk), but it's actually delicious! And using non-fat milk and sugar-free creamer makes it not too unhealthy, don't you think? :-)
Enjoy your Sunday!
