Crust Mix melted butter with Oreo crumbs and press in a 9-inch spring pan cover the bottom and 1 1/2" up the sides with crumbs, set aside. Note, you do not remove the filling of the cookies when you make crumbs out of them. Leave the filling in the cookies when you crush them. 

All Ingredients need to be at room temperature before beginning. Beat cream cheese until light and fluffy (You can add the 1 cup of butter as listed as an optional ingredient). Keep mixer on a low setting during the mixing and beating process. 

Add sugar gradually and continue beating cream cheese until mixed through. Add eggs one at a time and continue to beat until blended. Measure the vanilla, salt, and flour, pour into the cream cheese and egg mixture and beat until smooth. 

Add the sour cream and beat well. Turn off the mixer and stir in the six coarsely chopped Oreo cookies with a spoon. Pour cream cheese into the spring form pan and place the 8 coarsely chopped Oreo Cookies on top of the cream mixture. 

Place pan on the top rack and in the middle of a preheated oven at 325 degrees and bake for one hour. The Cheesecake will be done when it jiggles slightly in the middle when the pan is gently shaken. If the cheesecake is very jiggly, then cook for an additional 15 minutes. 

Turn the oven off.

When time is up prop the oven door open and let the cheesecake stay in the oven for one hour.   The oven should be turned off at this point. 

Remove from oven and let cool enough to place in the refrigerator for 24 hours. It is worth the anticipation. A cheesecake should season. The flavor ripens and becomes enriched. Yield: 16 servings
