Preheat your oven to 400°F (200°C). Line a 9-inch springform pan with crumpled parchment paper.
In a large bowl, beat softened cream cheese and granulated sugar until smooth and creamy.
Add eggs one at a time, mixing after each until just combined.
Stir in heavy cream, lemon zest, and lemon juice until smooth.
Sprinkle in flour and salt. Gently mix until just combined and smooth.
Pour batter into the prepared springform pan.
Bake for 50-60 minutes, until the top is deeply browned and the center is slightly jiggly.
Cool completely at room temperature, then refrigerate for at least 4 hours or overnight.
Remove from pan, peel away parchment, and serve chilled.
