Mix the crushed biscuits with melted butter until well combined. Press firmly into a tin to form the base. Chill in the fridge.
In a bowl, add double cream, cream cheese, and Nutella.
Whisk until thick and creamy, almost like ice cream consistency. This creates the perfect Nutella Cheesecake No Bake texture.
Spread the mixture evenly over the chilled base and smooth the top.
Refrigerate for at least 4 hours or overnight for best results.
Gently warm the Nutella for the topping until slightly softened.
Pour over the cheesecake and spread carefully.
Sprinkle chopped hazelnuts around the edges.
Chill again for 1 hour before serving.
