Make whipped cream topping.Sugar, salt, and heavy cream are whipped together using a handheld milk frother. Fluffy whipped cream is made in seconds. Set aside.
Simmer milk and take off heat. Stir in white chocolate chips until completely melted. Add vanilla extract, sea salt, and nutmeg.
Assemble drink.Pour white hot chocolate into a mug, top with whipped cream and garnish with a pinch of nutmeg.
White chocolate is naturally off-white and pale yellow in color due to the cocoa butter. If your chocolate chips are pure white, it means it contains little or no cocoa butter and other ingredients like artificial color or vegetable oil has been added.
The whipped cream can be made as stiff or soft as you like by adjusting the time you whisk. If you want a more pourable whipped cream with soft peaks that will stir into the drink easier, whisk until it thickens slightly. Make sure to move the handheld milk frother up and down to get air into the cream.
Whipped cream can be made ahead and stored in the refrigerator in an airtight container for up to 2 days. Stir it a little since it may have deflated a bit.
