Today's version is made with coffee.
This is how I make it:
Pour approx. 1/2 cup of Eggnog or Eggnog mixed with milk into your coffee cup. Heat in the microwave. Sprinkle in some cinnamon.
Add coffee. I use the medium button on my Keurig machine. Zip together with a frother.
If you want to be fancy (you do, trust me!), top with whipped cream and sprinkle cinnamon & nutmeg on top. Easy on the nutmeg, it can be strong!
(and do not, under any circumstances, count calories! lol)
