Step 1: Prepare the Base

1. Crumble the cookies in a food processor or in a freezer bag with a rolling pin until finely crushed. Mix the crumbs with the melted butter until well combined.
2. Press the cookie-butter mixture evenly into a greased springform pan (approx. 24 cm diameter) and form a firm base. Chill for about 10 minutes to set.

Step 2: Make the Filling

1. In a large bowl, thoroughly mix cream cheese, Nutella, and sugar. Add the eggs one by one, mixing well after each addition.
2. Stir in the vanilla extract. Whisk the agar-agar with a little water and add this mixture to the cheesecake filling. Mix everything well.

Step 3: Assemble and Bake

1. Pour the finished filling evenly over the chilled cookie base. Smooth the surface with a spatula.
2. Bake the cheesecake in a preheated oven at 160 °C (convection) for approx. 45-50 minutes, or until the filling is set. Let it cool to room temperature, then chill for at least 4 hours (or overnight).

Step 4: Serve

1. Garnish with vegetable cream before serving and enjoy!
