Method
Make the Hot Fudge
- In a saucepan, whisk together ¾ cup (180 g) heavy cream, ¼ cup (45 g) brown sugar, ¼ cup (30 g) Dutch-process cocoa powder, and a pinch of salt.
- Heat over medium, whisking constantly, until steaming but not boiling.
- Remove from heat and stir in 3 oz (85 g) finely chopped dark chocolate and 2 tbsp (30 g) unsalted butter until smooth and glossy.
- Transfer the hot fudge to the refrigerator and chill 20–30 minutes, until thick, spoonable, and pudding-like.
- Reserve ⅔ of the fudge for layering inside the cheesecake and keep ⅓ refrigerated for topping later.
Prepare the Pan
- Line the bottom of an 8–9 inch springform pan (heart-shaped or round) with parchment paper cut to just hang over the edge for easy removal.
- Do not grease the pan and do not wrap it in foil yet.
Make the Oreo Crust
- Preheat the oven to 350°F (175°C).
- Crush 24–26 Oreos (280 g) into fine crumbs. Stir in 6 tbsp (85 g) melted unsalted butter and a pinch of salt.
- Press the mixture firmly into the bottom of the prepared pan.
- Bake for 10 minutes, then remove and let cool completely.
- Reduce the oven temperature to 305°F (150°C).
Make the Chocolate Cheesecake Filling
- In a mixing bowl, beat 24 oz (680 g) full-fat cream cheese until completely smooth, scraping down the bowl often.
- Add ¾ cup (170 g) granulated sugar, ¼ cup + 1 tbsp (35 g) Dutch-process cocoa powder, 2 tbsp cornstarch, and ¼ tsp fine salt.
- Mix on low speed until just combined.
- Add 3 large eggs, one at a time, mixing on low speed after each addition.
- Add ½ cup (120 g) sour cream, 4 oz (120 g) melted and cooled dark chocolate, and 1 tsp vanilla extract. Mix just until smooth.
- Do not overmix. Overmixing incorporates air and causes cracking.
Assemble the Cheesecake (Fudge Pocket Method)
- Spoon a thin layer of cheesecake batter over the cooled crust using a large cookie scoop or spoon.
- Using a small cookie scoop or melon baller, drop rounded scoops of the thick hot fudge evenly across the batter.
- Add a little more cheesecake batter — it is okay if the fudge scoops are still partially visible.
- Add a few more fudge scoops, then finish with the remaining batter. The final layer of batter should mostly cover the fudge.
- Do not swirl.
- Use an offset spatula to gently smooth the top.
Wrap and Bake in a Water Bath
- Wrap the bottom and sides of the springform pan tightly with two layers of heavy-duty foil, then cover with a plastic shower cap for extra protection.
- Place the pan inside a large roasting pan. Pour hot or boiling water into the roasting pan until it reaches ½ to ⅔ up the sides of the springform pan.
- Bake at 305°F (150°C) for about 1 hour 30 minutes, until:
- The edges are set
- The center still has a slow, custardy wobble
- If it does not jiggle, it is overbaked.
Cool Properly (Critical Step)
- Turn the oven off, crack the oven door, and let the cheesecake cool inside the oven for 1 hour.
- Remove from the oven, cool completely at room temperature, then refrigerate overnight (at least 8 hours).
Make the Brownie Crumble (Next Day)
- Preheat the oven to 325°F (165°C) and line a baking sheet with parchment paper.
- Mix ¼ cup (60 g) melted unsalted butter, ⅓ cup (75 g) granulated sugar, 1 tbsp milk, ½ cup (60 g) all-purpose flour, ¼ cup (25 g) Dutch-process cocoa powder, and a pinch of salt until clumpy.
- Drop the crumble onto the baking sheet in loose, irregular clumps, about ½–1½ inches wide, spaced ½–1 inch apart. Do not press flat.
- Bake for 8 minutes, remove the pan, and gently break only the largest clumps.
- Return to the oven for 4–6 minutes more.
- The crumble will look slightly underdone when removed. This is correct — it will firm up and become crunchy as it cools. Do not overbake.
- Cool completely, then break into irregular chunks.
Make the Chocolate Whipped Cream
- In a small bowl, whisk 2 tbsp Dutch-process cocoa powder, 2–3 tbsp powdered sugar, and a pinch of salt.
- Add 2–3 tbsp of the heavy cream and whisk into a smooth paste.
- Add the paste to the remaining 1 cup (240 g) cold heavy cream, and add in ½ tsp vanilla extract, whip to soft–medium peaks.
Make the Chocolate Drizzle
- For ganache, heat ½ cup (120 g) heavy cream until steaming. Pour over 3 oz (90 g) finely chopped dark chocolate, let sit 2 minutes, then whisk until smooth.
- Alternatively, warm store-bought chocolate sauce until pourable.
Assemble and Serve
- Top the chilled cheesecake with the remaining fudge, heat up until softened and spread on top of cheesecake. Add brownie crumble on top, leave a little bit leftover to sprinkle on top of the whipped cream. Spoon chocolate whipped cream over the top, add rest of crumble. Drizzle generously with chocolate drizzle.
Notes
- Bake low and slow and remove while the center still has a slow, custardy wobble. If it doesn’t jiggle, it’s overbaked.
- Mix on low speed once eggs are added to avoid cracking.
- The hot fudge must be thick and spoonable before layering so it forms pockets.
- Do not swirl the fudge.
- The brownie crumble will look underdone when removed and will crisp as it cools.
- Works in an 8–9 inch heart-shaped or round springform pan.
Storage
- Refrigerate covered for up to 4 days.
- For best texture, store without toppings and add them before serving.
- Cheesecake (without toppings) can be frozen for up to 1 month.
Make-Ahead
- Bake the cheesecake 1 day ahead and chill overnight.
- Brownie crumble and hot fudge can be made 1–2 days ahead.
- Assemble with whipped cream and drizzles just before serving.
