Follow these steps to create your delicious Oreo Cheesecake Bars:

1. Prepare the Pan: Line an 8×8-inch square baking pan with parchment paper, leaving some overhang for easy removal later.
2. Make the Oreo Crust: In a medium bowl, combine the crushed Oreo cookies and melted butter. Stir until the mixture resembles wet sand.
3. Press the Crust: Firmly press the mixture into the prepared baking pan to create an even layer for the crust.
4. Mix the Cheesecake Filling: In a large bowl, beat the softened cream cheese until smooth. Gradually add the sugar and vanilla extract and continue mixing until combined.
5. Add Eggs: Add the eggs one at a time, mixing well after each addition until fully incorporated.
6. Pour the Filling: Carefully pour the cheesecake filling over the crust, spreading it evenly.
7. Chill: Cover the pan with plastic wrap or foil and place it in the refrigerator. Chill for at least 4 hours or until the cheesecake is firm.
8. Cut the Bars: Once set, use the parchment overhang to lift the cheesecake from the pan. Cut into squares.
9. Add Toppings: If desired, top each square with whipped cream and a sprinkle of crushed Oreos.
10. Serve: Enjoy your Oreo Cheesecake Bars chilled for maximum flavor and texture.
