Whip the cream with a pinch of salt in a large bowl until soft peaks form, about 3-5 minutes.

In a separate bowl, combine Nutella, sugar, and vanilla extract. Stir until smooth and creamy.

Gently fold half of the whipped cream into the Nutella mixture, then repeat with the remaining whipped cream.

Transfer the mousse into serving cups and chill in the refrigerator for at least 2 hours.

Garnish with chocolate shavings or whipped cream before serving.
