Ingredients

For the Crust:

1 ½ cups (15 full-sheet) plain graham cracker crumbs (about 180g)
6 tablespoons (85g) unsalted butter, melted
¼ cup (50g) granulated sugar
¼ teaspoon fine sea salt

For the Cheesecake Layer:

24 ounces (680g / 3 standard 8-oz blocks) full-fat brick cream cheese, at room temperature
1 cup (200g) granulated sugar
1 cup (240g) full-fat sour cream, at room temperature
2 teaspoons pure vanilla extract
3 large eggs, at room temperature
2 tablespoons (16g) all-purpose flour or cornstarch

For the Chocolate-Caramel Swirl:

12 ounces (340g) high-quality semi-sweet or bittersweet chocolate (60–70% cocoa), finely chopped
6 tablespoons (85g) unsalted butter
1 teaspoon pure vanilla extract
½ teaspoon instant espresso powder (optional but recommended)
¾ cup (180ml) thick, pourable homemade salted caramel sauce, warmed
Flaky sea salt, for finishing (e.g., Maldon)

Instructions

Step 1: Preheat your oven to 325°F (163°C). Grease a 9×13-inch metal baking pan and line it with parchment paper, leaving an overhang on two long sides for easy removal.

Step 2: In a food processor, pulse the graham crackers until they become fine crumbs. Add melted butter, sugar, and salt, then pulse until the mixture resembles wet sand. Press the crust mixture firmly and evenly into the prepared pan. Bake for 10 minutes, then cool completely on a wire rack for at least 20 minutes.

Step 3: Using a stand or hand mixer, beat cream cheese on medium speed until smooth, about 2 minutes. Add sugar and continue beating for 2 more minutes until fluffy. Mix in sour cream and vanilla extract until combined.

Step 4: Add eggs one at a time, mixing only until the yolk disappears after each addition. Fold in flour just until incorporated. Pour this cheesecake batter over the cooled crust and smooth the top. Refrigerate for 15 minutes.

Step 5: Melt chocolate and butter together in a double boiler until smooth. Remove from heat and stir in vanilla extract and espresso powder (if using). Let cool for 3–4 minutes until warm (95–100°F).

Step 6: Warm the caramel sauce until it’s fluid (about 100°F). Dollop the caramel over the chilled cheesecake layer, then dollop the chocolate mixture over the caramel. Using a skewer, gently swirl to create a marbled effect—do not overmix.

Step 7: Place the pan on a larger baking sheet to catch any drips. Bake in the preheated oven for 42–48 minutes until the edges are set and the center jiggles slightly. The internal temperature should read 150–155°F.

Step 8: Turn off the oven and crack the door open with a spoon. Let the bars rest inside the oven for 1 hour. Then transfer the pan to a wire rack and let cool completely for 2–3 hours. Cover and refrigerate for at least 8 hours, preferably overnight.

Step 9: Use the parchment paper overhang to lift the cheesecake slab out of the pan. Cut into 12–16 bars using a hot, dry knife. Sprinkle flaky sea salt and additional caramel sauce on top before serving, if desired.

Tips & Variations

Use full-fat brick cream cheese for the creamiest texture; low-fat versions can cause graininess and poor structure.

For a caffeine hint, add the optional espresso powder—it enhances the chocolate depth.

If you don’t have a food processor, place graham crackers in a sealed bag and crush with a rolling pin until finely ground.

Try topping with toasted nuts for extra crunch and flavor contrast.

FAQs

Can I use low-fat cream cheese or Neufchâtel?

No—reduced-fat versions contain added water and stabilizers that cause weeping, graininess, and poor structure. Full-fat cream cheese is essential for a creamy texture and proper setting.

Why did my bars crack?

Cracks often happen if the batter is too cold when baked, the oven temperature is too high, cooling is too rapid, or the eggs are overmixed. Use room-temperature ingredients, bake at a true 325°F (check with an oven thermometer), cool gradually in the oven, and avoid overbeating the batter.
