Simmer over low heat for about 10 minutes, whisking occasionally.
Add more regular milk or a dairy-free alternative to thin the mixture, if desired.
Pour into mugs when desired temperature and consistency has been reached.
(Optional) Serve with mini marshmallows or whipped cream. If serving with whipped cream, consider adding a sprinkling of fresh cinnamon or nutmeg to the top.
Notes
Note: You can put the can of coconut milk in the refrigerator overnight, which can make the hot chocolate creamier.Second Note: Using the can of coconut milk is going to make this a thicker hot chocolate. If you prefer, you can use regular milk or your favorite non-dairy milk substitute to either thin the recipe or instead of the canned coconut milk.
