Prepare premade pie crust in 9 inch pie pan and preheat oven to 425. Prick the bottom of the pie crust with the fork to avoid the bottom bubbling up. Bake for 10 minutes or so, until just beginning to brown.
Using a paddle attachment, mix together cream cheese and sugar. Scrape the bottom of the bowl and mix again briefly.
Scrape down the sides and bottom of the bowl again and add the eggs. Mix until thoroughly combined.
Add lemon juice, lemon zest, and vanilla and mix until just combined.
Lower oven temp to 350.
Pour filling into hot pie crust and bake for 30-40 minutes, until the center has a slight jiggle but is not liquid.
Allow to cool completely before chilling in the fridge for at least 4 hours, if not overnight.
Whip together whipping cream and powdered sugar until medium peaks form. Top pie as desired, either in rustic dollops or piped. Add lemon zest if desired.
