Add the milk and the mini chocolate chips to a frother, and blend on the cappuccino setting, or stiff foam setting.
Pour into a glass once the program has completed.
Meanwhile, dip the end of a toothpick into black food coloring, then make dots in the shape of a face on one end of the marshmallow. Re-dip into the food coloring as necessary. Add an orange sprinkle for a nose.
Top the hot chocolate with the snowman marshmallow. Enjoy!
