Preheat your oven to 400°F (200°C).
Grease a 9-inch round cake pan with butter.
In a large mixing bowl, beat the softened cream cheese until smooth.
Add the sugar and mix until well combined.
Pour in the heavy cream and mix until fully incorporated.
Whisk the eggs in a separate bowl and add them to the mixture.
Gently fold in the flour, vanilla extract, and salt.
Pour the batter into the prepared pan and smooth the top.
Bake for 40-45 minutes until the top is dark brown and the center is slightly jiggly.
Let it cool in the pan for at least an hour before refrigerating for 4 hours or overnight.
