Mix Dry Ingredients together
Add some of the almond milk and stir. Make sure everything is mixed into the milk. Cocoa powder is hyrdophobic. This makes mixing it in easier.
Add the rest of the milk and whisk. Don't quite bring to a boil. Stir in heavy cream and vanilla. Add chocolate if you want to add it.
Taste. If you like it, pour into a mug. Top with marshmallows or whipped cream. Enjoy.
