1 1/2 cups heavy whipping cream
1/2 cup marshmallow creme (fluff, divided)
1/3 cup hazelnuts (spread, Nutella, divided)
31/2 cups whole milk
chocolate sprinkles (or chocolate shavings for garnish)
Add 1 cup heavy cream and 1/2 cup marshmallow cream into a 1 pint whipped cream dispenser. Charge with 1 N20 charger and shake.
Refrigerate until needed.
In a medium heavy bottom saucepan, whisk together 1/3 cup hazelnut spread, remaining 1/3 cup marshmallow cream, 3 1/2 cups milk, and remaining 1/2 cup heavy cream over low heat until smooth and hot.
To serve, place one heaping tablespoon of hazelnut spread into the bottom of each of 4 clear glass mugs. Ladle in the hot chocolate carefully (do not stir) over spread, then top with a large dollop of the whipped cream. Garnish with sprinkles or chocolate shavings and serve with extra whipped cream.
