These Chocolate Cheesecake Bars are exactly what you want when chocolate and cheesecake crave each other. The recipe makes a dense, creamy filling set atop a crisp Oreo crust and finished with a glossy chocolate ganache and piped stars. No fiddly water baths or tiny pans—just a 9×13 pan and straightforward steps.

I tested the method to keep timing simple: a quick blind-bake for the crust, a chocolate-infused cheesecake baked until just set, then a chilled finish and a smooth ganache. The technique yields clean slices with a restrained sweetness and real chocolate depth.

If you like reliable, chocolate-forward desserts that travel well and slice cleanly, this is a keeper. I’ll walk you through the exact ingredients, the step-by-step bake, tool suggestions, common slip-ups, and a few sensible variations so you can make these with confidence.

The Ingredient Lineup

Ingredients

regular full-size package Oreo cookies, crushed into fine crumbs (36 sandwich cookies in total) — the base for a chocolate cookie crust; crush finely for even packing and structure.
8 tablespoons (4 ounces) unsalted butter, melted — binds the Oreo crumbs and yields a crisp, sliceable crust once baked.
12 ounces bittersweet chocolate, coarsely chopped — melted into the filling for deep chocolate flavor and a dense, fudgy texture.
1 and 1/2 pounds (24 ounces) full-fat cream cheese, at room temperature — the backbone of the filling; room temperature ensures a smooth, lump-free batter.
1 cup granulated sugar — provides sweetness and helps the texture set properly.
1/4 cup light brown sugar, packed — adds a touch of caramel notes and moisture to the filling.
2 Tablespoons unsweetened natural cocoa powder — reinforces chocolate flavor and deepens color without extra sugar.
4 large eggs plus 2 large egg yolks, at room temperature — contribute richness and structure; room temperature eggs incorporate more easily.
1 cup heavy cream, at room temperature — enriches the filling and helps it stay creamy while baking.
2 teaspoons vanilla extract — brightens and rounds the chocolate flavors.
16 ounces semi-sweet chocolate, finely chopped — used to make the glossy ganache that tops the bars.
1 and 1/4 cups heavy cream — heated and poured over the semi-sweet chocolate to create the ganache.

Cook Chocolate Cheesecake Bars Like This

Preheat the oven to 350°F. Line a 9×13-inch baking pan with heavy‑duty aluminum foil, leaving at least a 2‑inch overhang on two opposite sides, and spray the foil lightly with nonstick baking spray. Set the pan aside.
In a large bowl, combine the crushed Oreo crumbs and the melted butter; stir until the crumbs are evenly moistened.
Press the crumb mixture firmly into the bottom of the prepared pan and slightly up the sides. Bake the crust at 350°F for 10 minutes. Remove from the oven and transfer the pan to a wire rack to cool. Reduce the oven temperature to 325°F.
Set up a double boiler: fill a medium pot about one‑third full with water and bring it to a low simmer over medium heat. Place a heatproof bowl on top of the pot so the bottom of the bowl does not touch the water.
Put the 12 ounces coarsely chopped bittersweet chocolate into the bowl and reduce the heat to low. Stir occasionally until the chocolate is completely melted. Remove the pot from the heat and leave the bowl on top of the pot while you make the filling; set aside.
In the bowl of a food processor (or a mixer), pulse the room‑temperature cream cheese until smooth, scraping down the sides as needed (about 2 minutes).
Add the granulated sugar, packed light brown sugar, and unsweetened cocoa powder to the cream cheese and process/beat until smooth and fully combined.
With the mixer on low, add the 4 large eggs and 2 large egg yolks and the 1 cup room‑temperature heavy cream. Mix just until combined (about 20 seconds).
Using a silicone spatula, fold the melted bittersweet chocolate into the cream cheese mixture until evenly incorporated. Fold in the 2 teaspoons vanilla extract. Remove the bowl from the processor and stir the filling a few times with the spatula to ensure even blending.
Scrape the filling over the partially baked crust and smooth the top. Bake at 325°F for about 35 minutes, or until the center is set but still slightly jiggly. The cheesecake will finish setting as it cools.
Remove the pan from the oven and place it on a wire rack. Carefully loosen the foil from the pan edges, then run the tip of a knife around the inside edge of the pan to release the cheesecake. Allow the cheesecake to cool completely in the pan on the rack.
Once cooled to room temperature, transfer the pan to the refrigerator and chill for at least 4 hours (or until fully chilled) before removing from the pan and slicing.
To make the ganache, place the 16 ounces finely chopped semi‑sweet chocolate in a large heatproof bowl.
In a small saucepan over medium heat, bring 1 1/4 cups heavy cream to a rolling simmer, then immediately remove from the heat. Pour the hot cream over the chopped semi‑sweet chocolate and let sit for 1 minute. Whisk until the mixture is smooth and glossy.
Let the ganache cool until tepid. Spoon approximately 3/4 cup of the ganache into a large piping bag fitted with an open star tip and set the bag aside.
Pour the remaining ganache over the chilled cheesecake and spread evenly. Let the ganache set at room temperature for about 1 hour, or until firm.
Use the foil overhang to lift the cheesecake from the pan and transfer to a cutting board. Using a thin‑bladed sharp knife, slice into bars, wiping the knife clean between each cut.
Pipe a star of the reserved ganache onto each bar. Serve immediately, or store loosely covered in the refrigerator for up to 5 days.

Reasons to Love Chocolate Cheesecake Bars

They combine a crunchy chocolate-cookie base with a dense, chocolatey cheesecake layer and a shiny ganache top—three textures in one bite. The result is indulgent without being overly sweet, which keeps each bar balanced.

Made in a 9×13 pan, they scale easily for a crowd and slice into neat bars for serving. The chilling step does the heavy lifting: it firms the filling so you get clean slices that hold up on a plate or at a party.

Finally, the separate bittersweet (in the filling) and semi‑sweet (in the ganache) chocolates let you dial the richness and sweetness by swapping proportions or using the chocolates included in the recipe.

Ingredient Flex Options

Stick to the listed ingredients for the best, tested result. If you want small changes that stay within the recipe’s spirit, here are conservative options that use ingredients already in the recipe:

Use a little more or less of the 12 ounces bittersweet chocolate in the filling to nudge intensity—more bittersweet for deeper cocoa notes, less for a milder filling.
If you prefer a slightly sweeter finish, use a higher proportion of the 16 ounces semi‑sweet chocolate in the ganache (you can pour all of it and skip piping), since the ganache ingredient is already in the recipe.
If you want a firmer crust, press the Oreo crumbs slightly higher up the sides before baking instead of keeping it flat.

Recommended Tools

9×13-inch baking pan — required size for the recipe’s yield and baking times to match.
Heavy‑duty aluminum foil — for lining and easy removal using the overhang.
Food processor or stand mixer — smooths the cream cheese quickly and evenly.
Medium pot and heatproof bowl — for the double boiler when melting the bittersweet chocolate.
Silicone spatula — gentle folding and scraping ensure even texture without overworking.
Wire rack — cools the pan after baking so the cheesecake finishes setting properly.
Large heatproof bowl and a small saucepan — for making the ganache by pouring hot cream over chocolate.
Piping bag with open star tip and a thin‑bladed sharp knife — for finishing and clean slicing.

Slip-Ups to Skip

Don’t skip chilling. Cutting before the cheesecake is fully chilled will lead to messy slices and a soft ganache top. Give the minimum 4 hours in the fridge.

Avoid overheating the chocolate when melting. Use a low simmer for the double boiler and remove from heat as instructed. Overheated chocolate can seize or become grainy in the filling.

Don’t overmix the filling once eggs are added. Mix just until combined to limit air incorporation, which reduces the chance of cracks and keeps texture dense and even.

Year-Round Variations

Keep the core elements and adjust only presentation for different seasons. For summer gatherings, chill well and serve directly from the fridge. In cooler months, let the bars sit at room temperature for 5–10 minutes before serving for a silkier mouthfeel.

For holidays or special events, pipe slightly larger ganache stars and arrange bars on a decorative platter. The recipe’s components remain the same—only the look shifts—so the proven texture and flavor stay intact.

Pro Tips & Notes

Room temperature ingredients matter: cream cheese, eggs, and heavy cream incorporate more smoothly and reduce lumps. Plan ahead so nothing is cold straight from the fridge.
When pressing the crust, use the bottom of a measuring cup for an even, firm layer—this helps the crust hold together when sliced.
Remove the pan from the oven and allow it to cool on a wire rack; residual heat finishes the set without overbaking. The center should still be slightly jiggly when you pull it, per the directions.
Wipe your knife between cuts and run it under hot water and dry it for the cleanest slices. A thin‑bladed sharp knife works best.
Reserve about 3/4 cup ganache for piping as directed to add a professional-looking finish on each bar.

How to Store & Reheat

Store the bars loosely covered in the refrigerator for up to 5 days. The ganache maintains a nice sheen when chilled. For a travel-friendly container, line the container with parchment and layer bars with parchment between them.

If you prefer them a touch softer, remove individual bars from the fridge 10–15 minutes before serving. Do not microwave whole bars—briefly warming a single bar for 5–8 seconds can soften the ganache and make the texture more like a chocolate cheesecake mousse, but watch closely to avoid melting.

Time to Try It

Gather the ingredients and set aside an afternoon for a straightforward, impressive bake. Line the pan, press that Oreo crust, and follow the step-by-step method above. The result: glossy, chocolatey bars that slice cleanly and travel well—great for potlucks, parties, or quiet dessert nights.

When you make them, note any tiny tweaks you prefer so the next batch is perfectly yours. Then share a photo and a note: these Chocolate Cheesecake Bars are durable, indulgent, and reliably delicious.
