Preheat the oven to 220°C/425°F (200°C/425°F fan-forced oven). Prepare a 9-inch cake or springform pan lined with parchment paper.
In a large mixing bowl, beat the salt, eggs, sugar, cacao powder, vanilla powder, and dairy-free cream cheese until smooth and creamy.
Mix in the heavy cream, chocolate pastry cream, and warm melted chocolate until fully incorporated.
Pour in the chocolate cheesecake batter into the prepared cake pan. Level the top with a spoon or spatula.
Bake for 30-35 minutes, or until the top gets slightly burned and the center is set but still slightly jiggly. If you prefer to make thicker cheesecake, bake it longer.
Remove from the oven. Allow the chocolate cheesecake to cool on a wire rack. The cheesecake will slightly deflate as it cools down.
Once completely cool, refrigerate for at least 4 hours or overnight before cutting and serving.
