Press into a 9 x11 inch pan lined with parchment paper. Refrigerate until cold.
Prepare the Cheesecake:
In a large mixing bowl with a hand mixer, or In the bowl of a stand mixer fitted with the paddle attachment, beat cream cheese until softened and smooth.
Add sugar and continue to beat until no visible sugar granules remain. Add lemon juice, vanilla and salt. Beat to combine the cream cheese mixture.
Switch to whisk attachment and add cream to bowl. Whisk on medium high until stiff peaks form.
