Using the double broiler method, melt the chocolate over medium to low heat and add the milk, cream, sugar, and vanilla extract.
Continually stir until the chocolate comes to a simmer (not boil). Do not let the chocolate burn.
Once the chocolate begins to simmer lightly, check the thickness. It should be thicker than American Hot Chocolate, but not as thick as chocolate fondue.
If it's too thick, add a little bit more milk. Pour into a cup, top with whip cream, homemade marshmallows, edible lavender or chocolate shavings and serve immediately.
