Creating the Fluffy Hazelnut Chocolate Mousse is a straightforward process, but attention to detail will elevate your results. Follow these steps to ensure a perfect mousse every time:

1. Prepare the Whipped Cream
   • Pour 1 cup of heavy whipping cream into a chilled mixing bowl.
   • Add 1 tablespoon of powdered sugar and the vanilla extract.
   • Beat the mixture with an electric mixer on medium speed until soft peaks form. Be careful not to overbeat, as this could result in butter instead of whipped cream.
   • Set aside in the refrigerator.
2. Combine Hazelnut Spread and Cocoa
   • In a separate bowl, combine the hazelnut spread, cocoa powder, and a pinch of salt.
   • Mix well until the cocoa is fully integrated into the hazelnut spread, creating a smooth, chocolatey paste.
3. Blend the Mixtures
   • Gently fold half of the whipped cream into the hazelnut-cocoa mixture. Use a spatula to ensure you maintain the light texture.
   • Once combined, fold in the remaining whipped cream, ensuring the mixture is smooth and fluffy.
4. Chill the Mousse
   • Spoon the mousse into individual serving glasses or bowls.
   • Cover and refrigerate for at least 2 hours, allowing the flavors to meld and the mousse to set.
5. Garnish and Serve
   • Before serving, whip the remaining cup of heavy cream with the remaining 2 tablespoons of powdered sugar until soft peaks form.
   • Top each serving of mousse with a dollop of whipped cream.
   • Garnish with dark chocolate shavings and chopped hazelnuts for an added touch of elegance and texture.
