Preheat your oven to 325°F and grease a 9-inch springform pan.
In a bowl, combine the melted butter with the Oreo crumbs, then press the mixture into the bottom of the prepared pan.
In a large mixing bowl, beat the cream cheese until smooth.
Add in the sugar, mixing until well combined.
Add the eggs one at a time, beating well after each addition to ensure a smooth consistency.
Mix in the sour cream and vanilla extract.
Stir in the coarsely chopped Oreo cookies gently with a spoon.
Pour the cream cheese mixture over the crust in the springform pan.
Bake on the top rack in the middle of the oven for about 1 hour and 15 minutes.
Once the cheesecake has finished baking, let it cool completely before removing it from the pan.
