Spicy hot chocolate, with some whipped cream and dark chocolate flakes
A teaspoon of Hershey's Dutch chocolate powder (the baking variety, so there's only chocolate, and nothing else) mixed with a 3/4th cup of hot water, and two tablespoons of half and half (I use Land O Lakes Mini Moo's). A pinch of dried smoked chipotle powder gives that spicy punch with a subtle smoky flavor, and a sachet of your preferred sweetening agent. Topped off with some light whipped cream and chocolate flakes. It's not winter yet; I'm just getting ready.
