Using a hand or stand mixer, whisk together the softened cream cheese and sour cream until smooth and creamy.
Add in the powdered sugar, granulated sugar, lemon juice, vanilla extract, and salt and mix until well combined.
Using a silicone spatula, gently fold in the 2 cups of prepared whipped cream until well combined.
Remove crust from freezer or fridge and pour filling over top of crust. Spread evenly using an offset spatula.
Cover with plastic wrap or aluminum foil and refrigerate for at least 12 hours. This will allow the ingredients to set up properly.
Use a knife to loosen the cheesecake around the edge of the springform pan and remove the rim of the pan.
Cut into slices and serve!
