In a saucepan, heat the whole milk over medium heat until it begins to steam, but do not let it boil.
Add the chopped white chocolate, stirring continuously until it has fully melted and the mixture is smooth.
Stir in the double cream, vanilla extract, and a pinch of sea salt, mixing well to combine.
Once heated through, remove the saucepan from the heat.
Pour the white hot chocolate into mugs, topping each with a generous dollop of whipped cream and a sprinkle of white chocolate shavings for an elegant finish.
Serve immediately.
