Chantal's New York Cheesecake

From allrecipes.com

15 graham crackers, crushed
2 tablespoons butter, melted

4 (8 ounce) packages cream cheese
1 1/2 cups white sugar
3/4 cup milk
4 eggs
1 cup sour cream
1 tablespoon vanilla extract
1/4 cup all-purpose flour

DIRECTIONS
Preheat oven to 350 degrees F (175 degrees C). Grease a 9 inch springform pan.
In a medium bowl, mix graham cracker crumbs with melted butter. Press onto bottom of springform pan.
In a large bowl, mix cream cheese with sugar until smooth. Blend in milk, and then mix in the eggs one at a time, mixing just enough to incorporate. Mix in sour cream, vanilla and flour until smooth. Pour filling into prepared crust.
Bake in preheated oven for 1 hour. Turn the oven off. Take a sharp knife and insert between cake and side of pan to loosen. Let cake cool in oven with the door closed for 1 hour. Remove and let cool. This prevents cracking. Chill in refrigerator until serving.
