Add all the hot chocolate ingredients together in a pot over medium low heat. Be sure to whisk the mixture often to prevent anything sticking/burning on the bottom.
When the hot chocolate is steaming and everything is smooth, pour into mugs and top with the coconut whipped cream and marshmallows. Enjoy!
Matcha Coconut Whipped Cream
For the coconut whipped cream, beat all ingredients until smooth with an electric mixer for about 2 minutes.
Notes
Make sure the canned coconut cream is refrigerated overnight before whipping.
