With an electric mixer on medium high beat cream cheese till smooth. Gradually add sugar and beat until combined. Beat in vanilla. Whisk the eggs in a measuring cup and drizzle into cream cheese mixture a little at a time. Beat well and scrape down sides as needed. Beat in sour cream and salt it should be very creamy at this point. Stir in chopped cookies by hand.
