Preheat the oven to 375 degrees Fahrenheit. Line a baking pan with parchment paper and set aside. In a bowl, mix together crushed Oreo cookies, melted butter, and sugar until combined. Press the mixture onto the prepared baking pan.
Bake for 10 minutes or until golden brown. Let cool completely before proceeding with the next step. In another bowl, beat together cream cheese, sugar, eggs, and vanilla flavoring until creamy.
Pour the cream cheese mixture over the cooled cookie crust and spread evenly. Top with pieces of Oreo cookies by pressing them lightly into the cream cheese layer.
Bake in preheated oven for 30-35 minutes or until the cream cheese layer is no longer jiggly. Let cool completely before cutting into cubes and serving.
