Ultimate Chocolate Cheesecake
This is the kind of dessert that stops people mid-conversation at the dinner table, the one everyone asks you to bring to every gathering. This cheesecake is built on three layers of pure chocolate indulgence: a crisp, buttery Oreo cookie crust, a dense and velvety chocolate cream cheese filling made with real melted chocolate, and a silky chocolate ganache poured right over the top.
Equipment
- 9-inch springform pan
- Stand mixer or electric hand mixer
- Large roasting pan - for water bath
- Food processor - or zip-lock bag and rolling pin for Oreo crumbs
- Double boiler or microwave-safe bowl - for melting chocolate
- Digital kitchen scale - highly recommended for accuracy
- Large mixing bowls
- Rubber spatula
- Measuring cups and spoons
- Aluminum foil - wide, heavy-duty
- Offset spatula or butter knife - for smoothing the top
- Wire cooling rack
Ingredients
- 24 cookies Oreo cookies - about 2 cups or 240g of crumbs, filling included
- 5 tablespoons unsalted butter - 70g, melted
- 10 oz semi-sweet chocolate - 280g, finely chopped (from baking bars, not chips)
- 24 oz full-fat cream cheese - 680g, at room temperature (block-style, not spreadable)
- 1 cup granulated sugar - 200g
- 3 tablespoons unsweetened cocoa powder
- 1 cup full-fat sour cream - 240g, at room temperature
- 3 large eggs - at room temperature
- 2 teaspoons pure vanilla extract
- 1/4 teaspoon fine salt
- 6 oz semi-sweet chocolate - 170g, finely chopped (for ganache)
- 3/4 cup heavy cream - 180ml (for ganache)
- Whipped cream - for garnish (optional)
- Chocolate shavings or curls - for garnish (optional)
- Fresh raspberries or strawberries - for garnish (optional)
Instructions
- Preheat oven to 325°F (163°C). Wrap the outside of a 9-inch springform pan with two layers of heavy-duty foil. Grease the inside lightly.
- Pulse 24 Oreo cookies in a food processor until fine crumbs form. Mix with 5 tablespoons melted butter, then press firmly into the bottom and 1 inch up the sides of the pan. Bake for 8 minutes and cool.
- Melt 10 oz semi-sweet chocolate in a microwave in 30-second bursts, stirring between each, until smooth. Set aside to cool to room temperature for 10-15 minutes.
- Beat 24 oz room-temperature cream cheese in a stand mixer on medium speed for 2 minutes until smooth. Add 1 cup sugar and beat for 2 more minutes until light and fluffy.
- Add 3 tablespoons cocoa powder and 1/4 teaspoon salt, mixing on low until combined. Add 1 cup sour cream and 2 teaspoons vanilla, mixing until smooth. Fold in the cooled melted chocolate.
- Add eggs one at a time, mixing on low after each addition just until incorporated. Do not over-mix. Fold the batter with a rubber spatula to ensure everything is evenly combined.
- Pour the filling over the cooled crust and smooth the top. Place the foil-wrapped pan in a large roasting pan and pour boiling water into the roasting pan to reach 1 inch up the sides of the springform pan.
- Bake for 60-70 minutes until the edges are set and the center has a slight wobble. Turn off the oven and leave the cheesecake inside with the door cracked open for 1 hour.
- Remove the cheesecake from the oven and cool on a wire rack for 1-2 hours until it reaches room temperature. Cover loosely with plastic wrap and refrigerate for at least 6 hours, ideally overnight.
- Place 6 oz semi-sweet chocolate in a heatproof bowl. Heat 3/4 cup heavy cream until steaming, pour over the chocolate, and let sit for 2-3 minutes. Stir until smooth and glossy. Cool for 10 minutes until slightly thickened.
- Run a knife around the inside edge of the pan, then release the springform. Place the cheesecake on a serving plate. Pour the ganache over the top and spread to the edges. Refrigerate for 20-30 minutes to set the ganache.
- Decorate with whipped cream, chocolate shavings, or fresh berries before serving. Slice with a clean, sharp knife wiped between cuts for perfect slices.
Notes
- Room temperature ingredients are essential: Take cream cheese, eggs, and sour cream out of the refrigerator at least 1-2 hours before starting to ensure a smooth, lump-free batter.
- Don't over-mix after adding eggs: Mix on low speed and stop as soon as each egg disappears into the batter. Over-mixing incorporates too much air, which can cause cracking and a spongy texture.
- Cool the melted chocolate: Allow the melted chocolate to cool to just barely warm before adding to the cream cheese mixture. Hot chocolate can scramble the eggs or cause the batter to seize.
- Double-wrap with foil: Use two generous layers of wide heavy-duty foil around the springform pan to prevent any water from seeping in during the water bath, which would ruin the crust.
- Use boiling water: Always use boiling water (not hot tap water) for the water bath to maintain temperature and create consistent steam throughout the bake.
- Don't skip the overnight chill: An overnight rest in the refrigerator is what transforms the texture from loose to perfectly dense and creamy. Slicing too early will result in a soft, under-set filling.
- Run a knife around the edges: Before releasing the springform pan, run a thin knife or offset spatula around the inside edge to prevent the sides from pulling and cracking as the cheesecake is unmolded.
- Variation ideas: For a mocha version, add 1 tablespoon instant espresso powder with the cocoa powder. For mint chocolate, swap vanilla extract for 1 teaspoon peppermint extract. For a raspberry swirl, drop spoonfuls of seedless raspberry jam over the filling and swirl before baking.
- Storage: Refrigerate covered for up to 5 days. Freeze the whole cheesecake or individual slices for up to 3 months. Thaw overnight in the refrigerator before serving.
- Gluten-free option: Use gluten-free Oreo-style cookies for the crust and ensure the baking chocolate and cocoa powder are certified gluten-free.
