Oreo Cheesecake Brownie Bars

Introduction

These Oreo Cheesecake Brownie Bars combine three iconic desserts into one show-stopping treat. You get a fudgy brownie base, a layer of creamy cheesecake studded with Oreo chunks, and a rich chocolate ganache finish. It’s the ultimate indulgence for any chocolate and cheesecake lover.

Prep & Cook Time

Prep Time: 15 minutes

Cook Time: 75 minutes

Total Time: 90 minutes (plus cooling time)

Servings: 16 bars

Ingredients

• 18.4 ounce box brownie mix (plus ingredients needed for brownie mix)
• 22 Chocolate Cream Oreos (divided)
• 8 ounces cream cheese (room temperature)
• 1/4 cup granulated sugar
• 2 tablespoon full-fat sour cream
• 1 large egg
• 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• 1/4 cup chocolate chips
• 1/4 cup heavy whipping cream

Instructions

1. Preheat your oven to the temperature specified on the brownie mix box (typically 325°F or 350°F). Line a 9×9 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
2. Prepare the brownie batter according to the package directions. Coarsely chop 14 of the Oreo cookies and gently fold them into the brownie batter. Pour the batter into the prepared pan, spreading it into an even layer.
3. In a medium bowl, beat the room temperature cream cheese and granulated sugar together until smooth and creamy. Beat in the sour cream, egg, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) until just combined.
4. Roughly chop the remaining 8 Oreo cookies and fold them into the cream cheese mixture. Drop large spoonfuls of the cheesecake mixture over the brownie batter in the pan. Use a knife or offset spatula to gently swirl the two layers together, creating a marbled effect.
5. Bake for 45-55 minutes, or until the edges are set and the center only has a slight jiggle. The brownie layer should be baked through (a toothpick inserted into the brownie portion should come out with moist crumbs, not wet batter). Allow the bars to cool completely in the pan on a wire rack.
6. Once the bars are cool, make the ganache. Place the chocolate chips in a small heatproof bowl. Heat the heavy whipping cream in a small saucepan over medium heat until it just begins to simmer. Pour the hot cream over the chocolate chips, let it sit for 1 minute, then stir until smooth. Pour the ganache over the cooled bars and spread into an even layer.
7. Refrigerate the bars for at least 4 hours, or until the ganache is set and the bars are firm. Use the parchment paper overhang to lift the entire slab out of the pan. Cut into 16 squares with a sharp knife, wiping the blade clean between cuts for neat bars.

Variations

• Cookie Dough Swirl: Instead of swirling the cheesecake, drop small spoonfuls of edible chocolate chip cookie dough onto the brownie batter with the cheesecake for a triple-layer treat.
• Individual Servings: Bake the layers in a lined muffin tin for perfectly portioned “cupcake” style bars, reducing the bake time to 20-25 minutes.
• Frozen Treat: After chilling, cut and wrap bars individually. Serve them semi-frozen for a firmer, ice cream-like texture.
• Salted Caramel Drizzle: Before serving, drizzle the top with store-bought salted caramel sauce to add a sweet and salty contrast.

Tips for Success

• Ensure your cream cheese is truly at room temperature to avoid lumps in the cheesecake layer.
• Let the bars cool completely and chill thoroughly before cutting. This ensures clean layers and makes slicing much easier.
• For clean cuts, use a sharp knife and wipe it with a hot, damp cloth between each slice.

Storage & Reheating

Store leftover bars in an airtight container in the refrigerator for up to 5 days. They are best served cold. For longer storage, you can freeze the bars (wrapped tightly) for up to 2 months. Thaw in the refrigerator overnight. No reheating is necessary or recommended.

FAQ

Can I use a different size pan?

A 9×9 inch pan is ideal for thick bars. You can use an 8×8 inch pan for even thicker bars, but you may need to add 5-10 minutes to the bake time. A 9×13 inch pan will yield thinner bars and require a shorter bake time (start checking at 30-35 minutes).

My cheesecake layer cracked. What happened?

This can happen from over-mixing the cheesecake batter (which incorporates too much air) or from over-baking. Baking just until the center has a slight jiggle and cooling the bars gradually in the oven with the door propped open can help prevent cracks.

Can I use homemade brownie batter?

Absolutely. Use your favorite homemade brownie recipe for the base, aiming for a batter quantity that fits a 9×9 inch pan.

Do I have to make the ganache topping?

No, the ganache is optional but recommended for extra decadence. You can simply dust the top with powdered sugar or top with more crushed Oreos.

Can I use reduced-fat cream cheese or sour cream?

For the best texture and flavor, full-fat products are recommended. Low-fat alternatives may result in a less creamy cheesecake layer that can be more prone to weeping or cracking.

How do I know when the bars are done baking?

The edges will be fully set and pulling slightly away from the pan. The center should have a slight, gentle jiggle when you shake the pan—it will firm up as it chills. A toothpick inserted into the brownie portion (not the cheesecake swirl) should come out with a few moist crumbs.
