Beat cream cheese until smooth and fluffy.
Mix in pumpkin, eggs, vanilla, salt, cinnamon, ginger, and nutmeg until combined.
Gradually blend in powdered sugar on low, then beat until silky.
Pour filling over the crust and smooth the top.
Bake 38–45 minutes, until edges are set and the center jiggles slightly.
Cool completely. Chill 1 hour for cleaner slices, then cut and serve.
