This Oreo tiramisu recipe is a fun twist on the classic Italian dessert. Using a food processor, crush Oreos into fine crumbs and mix with melted butter. Press the mixture into a baking dish and chill. Meanwhile, prepare the mascarpone filling by beating mascarpone cheese, sugar, and vanilla extract until smooth. Layer the filling and crushed Oreos over the crust and chill for a few hours before serving.
