Pour milk into a glass microwave safe measuring cup or large mug.
Add all other ingredients and heat for about 1 minute in microwave at high power. Stir and continue heating in 30 second intervals, stirring after each, until desired temperature. Top with fresh whipped cream and/or marshmallows and serve.
Notes
*Use dairy-free milk for vegan. I like using unsweetened vanilla almond or cashew milk.
