Preheat oven to 300".
Grease a 10" Spring form pan.
Combine 1 1/2 cups cookie crumbs and the melted butter.
Mix to combine and press into the bottom of the pan.
Refrigerate while preparing the filling.
In a large bowl combine the cream cheese, sour cream, and the sugar mixing until smooth. You can use a stand mixer with a paddle attachment or a hand mixer.
Add the eggs and the vanilla, mix until combined, then fold in the crushed Oreo cookies.
Pour filling over the crust.
Place the spring form pan onto a baking sheet and wrap in a kitchen towel. This is optional, you do not have to do this but according to the recipe it keeps the cake from cooking too fast.
Bake for 1 hour 20 minutes.
Turn off the oven and open the door 4 inches, leave cheesecake in the oven for an additional 30 minutes.
Remove from the oven, cool 30 minutes then refrigerate overnight.
You can garnish the cheesecake with mini Oreos and drizzle with hot fudge or you can just eat it as is, it is excellent either way.
