Preheat oven to 350. Cut 1/2 cup butter (1 stick) into the 1 cup of flour until fine crumbs. Press into a 9×9 ungreased glass pan. Bake for 18-20 minutes until set. Let cool completely.
With an electric handheld beater, beat together 1 cup heavy cream, 2 TBSP confectioners sugar and vanilla extract. Beat until stiff peaks form.
With your handheld beater, beat together 4 oz (1/2 block) of cream cheese at room temperature with the 1/2 cup confectioners sugar. Carefully fold a generous 1/2 cup of your whipped cream into the cream cheese mixture. Set aside.
On top of the cooled cookie layer dollop the cream cheese mixture. Spread evenly with an offset spatula. Next spread the cooled lemon pie filling on top of the cream cheese layer. Finally top with the rest of your whipped cream! Refrigerate for at least 2 hours. Slice and serve chilled! Store any extra covered and in the refrigerator. Can double to make a 9×13!
