- 50 g Powdered Sugar (Sweetens the crust)
- 100 g Dark Chocolate (Using 100g is recommended)

How to Make Chocolate Hazelnut Tart Step-by-Step
- Step 1: Preheat your oven to 350°F. In a food processor, grind the chocolate sandwich cookies and blanched hazelnuts together. Combine with melted butter and powdered sugar until you reach a wet sand consistency. Firmly press the mixture into a 10” tart pan and bake for 12 minutes. Allow to cool completely.
- Step 2: Finely chop the dark and milk chocolate. Heat the heavy cream in a saucepan until steaming, then pour it over the chopped chocolate. Let it rest for a minute before stirring until smooth and glossy. Fold in the chopped hazelnuts and carefully pour the ganache into the cooled crust.
- Step 3: Toast the hazelnuts on a baking sheet for about 10 minutes until fragrant. Let them cool, then process in a food processor until they form a creamy paste. Set aside to cool further.
- Step 4: In a mixing bowl, beat the cream cheese until smooth. Add in the brown sugar, salt, and a splash of vanilla, mixing until combined. Incorporate the hazelnut butter, then in a separate bowl, whip the heavy cream until it reaches soft peaks. Gently fold the whipped cream into the cream cheese mixture until fluffy.
- Step 5: Spread the hazelnut mousse over the ganache layer in the crust. Cover the tart and refrigerate for at least 4 hours or overnight for the best results.
