These Oreo Cheesecake Bars are creamy, rich, and packed with cookies and cream flavor. They have a dark chocolate cookie crust, a smooth vanilla cheesecake filling, chopped chocolate sandwich cookies inside, and extra cookie pieces sprinkled over the top.
This recipe gives you the taste of a classic cookies and cream cheesecake without needing a springform pan or a water bath. Everything bakes in a square pan, chills until firm, and slices into neat dessert bars.
The texture is the best part. The crust is dark and slightly crunchy, the cheesecake layer is soft and creamy, and the cookie pieces add little chocolatey bites throughout. These bars are perfect for parties, holidays, potlucks, bake sales, dessert trays, or a simple weekend dessert.
Ingredients You’ll Need
Chocolate Sandwich Cookies
Use chocolate sandwich cookies for the crust, filling, and topping. You can use Oreo cookies or any generic chocolate sandwich cookies.
Cream Cheese
Softened full-fat cream cheese gives the smoothest and richest filling.
Granulated Sugar
Sugar sweetens the cheesecake layer without overpowering the cookie flavor.
Sour Cream
Sour cream makes the filling creamier and adds a small tang that balances the sweetness.
Eggs
Eggs help the cheesecake layer set while baking.
Vanilla Extract
Vanilla gives the filling a soft bakery-style flavor.
Butter
Melted butter holds the cookie crumb crust together.
Flour
A small amount of flour helps the bars set and slice neatly.

- 1/2 cup granulated sugar

How to Make Oreo Cheesecake Bars
Step 1: Prepare the Pan
Preheat the oven to 325°F.
Line an 8×8-inch baking pan with parchment paper. Leave a little parchment hanging over the sides so you can lift the bars out after they chill.
Lightly grease the parchment so the crust releases cleanly.
Step 2: Make the Cookie Crust
Add the chocolate sandwich cookies to a food processor and pulse until they turn into fine crumbs.
Pour the crumbs into a bowl and mix with melted butter. The mixture should look like damp crumbs and hold together when pressed.
Press the crust firmly into the bottom of the prepared pan. Use the bottom of a measuring cup to make it even and compact.
Bake for 8 minutes, then let it cool slightly while you make the filling.
Step 3: Make the Cheesecake Filling
In a large bowl, beat softened cream cheese and sugar until smooth.
Add sour cream, eggs, vanilla extract, and flour. Mix just until combined.
Do not overmix after adding the eggs. Too much air can make the cheesecake puff up while baking.
Fold in the chopped chocolate sandwich cookies with a spatula.
Step 4: Fill the Pan
Pour the cheesecake filling over the baked cookie crust.
Spread it evenly with a spatula.
Sprinkle the crushed cookies over the top. Press them down very lightly so they stick to the cheesecake layer.
Step 5: Bake
Bake for 32 to 38 minutes, or until the edges look set and the center still has a slight gentle jiggle.
Do not wait until the center looks fully firm. The bars will continue to set as they cool.
Let the pan cool at room temperature for about 1 hour. Then refrigerate for at least 4 hours, or overnight for the cleanest slices.
Step 6: Slice and Serve
Lift the chilled bars out of the pan using the parchment paper.
Slice into squares with a sharp knife. Wipe the knife between cuts for cleaner edges.
Serve chilled.
Tips for the Best Oreo Cheesecake Bars
Use softened cream cheese. Cold cream cheese can leave lumps in the filling.
Pack the crust firmly. A loose crust will crumble when you cut the bars.
Do not overmix the cheesecake filling after adding the eggs.
Use chopped cookies in the filling, not only crumbs. Cookie pieces give better texture.
Chill the bars fully before slicing. This is the most important step for clean squares.
Use parchment paper so the bars lift out easily.
Wipe your knife between cuts for a cleaner dessert tray look.
Make-Ahead Instructions
These bars are great for making ahead because they need time to chill.
Bake them the day before serving, refrigerate overnight, then slice the next day.
The texture becomes firmer and cleaner after a full chill.
How to Store
Store Oreo cheesecake bars in an airtight container in the refrigerator for up to 5 days.
Keep them chilled until ready to serve.
Frequently Asked Questions
Can I use generic chocolate sandwich cookies?
Yes. Generic chocolate sandwich cookies work well. They are also better for original food photos because you can avoid visible branding.
Can I make these without sour cream?
Yes. Use plain Greek yogurt instead, or leave it out. Sour cream gives the filling a smoother texture.
Why did my cheesecake bars crack?
They may have been overmixed or overbaked. Mix gently after adding eggs and bake only until the center slightly jiggles.
Can I use a 9×9-inch pan?
Yes. The bars will be slightly thinner and may bake a little faster.
Do these bars need to be refrigerated?
Yes. Since they contain cream cheese and eggs, keep them refrigerated.
Can I double the recipe?
Yes. Double the ingredients and bake in a 9×13-inch pan. Add a few extra minutes if needed.
