In a medium saucepan, place the whole milk and heat it over medium-low until it begins to steam; do not let it boil.

Finely chop the dark chocolate and add it to the saucepan. Whisk continuously until the chocolate is melted and the mixture is smooth and glossy.

Blend the heavy cream into the chocolate mixture, making sure it’s fully incorporated.

Add the vanilla extract and a pinch of sea salt, whisking briefly to blend.

Maintain over low heat while stirring until it reaches your preferred temperature, taking care not to boil.

Ladle the hot chocolate into mugs, leaving space at the top for toppings.

Add a generous mound of whipped cream to the top of each mug.

Garnish with chocolate shavings before serving.
