Add 36 Oreos into food processor. Pulse until fine crumbs. Pour in melted butter, and pulse again.
Press crumbs tightly into the springform pan, going about an inch up the side of the pan, making sure the bottom is pressed out evenly.Bake for 12 minutes, turning half way through. Remove from oven and allow to cool.
In the bowl of a stand mixer, beat cream cheese until smooth. Add sugar, and beat again. Add eggs, one at a time, then mix in sour cream and vanilla. Add flour and salt, and stir just until combined. Gently fold in bag of mini Oreos.
Pour mixture into crust swirling top for an even finish. Place pan on a cookie sheet, and bake for 1 hour and 30 minutes, checking and turning every 30 minutes. Be sure to bake until center of cheesecake only slightly jiggles when you shake it.
Turn off oven, prop open door, and let cheesecake cool in oven for 1 hour. Allow to cool completely on a cooling rack before covering with foil, and refrigerate overnight.
