Reduce oven to 325°. With a hand mixer or stand mixer, beat cream cheese at medium speed until creamy. Add brown sugar and flour and beat until fluffy. Add eggs one at a time, beating well after each one. Stir in cream and vanilla. Pour over pecan filling. Bake for 1 hour. Turn off oven and leave cheesecake in oven with the door closed for 1 hour. Remove from oven and run a knife along the outside edges to loosen cheesecake from sides of pan. Let cool. Chill for at least 4 hours before serving.
