Put your chocolate chips, cream, sugar, hot chocolate mix, and vanilla in a pot, and melt together. You will want to stir constantly.
Once melted, move pan to fridge and let cool enough to scoop out a stiff ball. (About an hour or so)
Make scoops, about 1 heaping tablespoon, and put on freezer paper on baking sheet
Stick in freezer for 20 minutes or so to harden a little further (You may be able to skip this step if you refrigerated for a longer time)
Roll into balls
Roll in your choice of goodies: candy canes crushed up, sprinkles, cinnamon, marshmallows, m&m's, etc.
Cover and chill until ready to eat/use
Stir into a mug of hot milk or eat plain!
