Cookies and Cream Dark Chocolate Oreo Cheesecake Step-by-step instructions

Before you start

Before starting, bring the cream cheese, eggs, and sour cream to room temperature so the batter mixes smoothly. Preheat the oven to 350°F (175°C) and prepare a 9-inch springform pan by wrapping the outside with foil.

Crush enough chocolate cookies to make 1 1/2 cups of crumbs for the crust, and chop the remaining 20 cookies into chunky pieces. Grate the 70% dark chocolate using a box grater to yield 1/2 cup of shavings. Have all equipment ready: mixing bowls, an electric mixer, a rubber spatula, and a roasting pan for the water bath.

Instructions

Crust and Batter

1. 1Prepare the crust and batter
   Heat the oven to 350°F (175°C). Wrap the outside of a 9-inch springform pan with foil. In a bowl, combine 1 1/2 cups chocolate cookie crumbs with 6 tablespoons melted butter; press firmly into the bottom of the pan. Bake for 10 minutes, then cool. In a large bowl, beat the cream cheese and sugar until smooth. Add the vanilla bean paste, then the eggs one at a time, beating well after each. Mix in the sour cream until just combined.
   Look for The batter should be smooth and creamy, with no lumps. The cookie pieces are chunky, not fine crumbs.
   Tip Have all ingredients at room temperature to prevent curdling. Beat just until incorporated; overmixing can cause cracks.
2. 2Fold in the cookies and chocolate
   Gently fold the chopped dark chocolate cookies and the grated chocolate shavings into the cream cheese batter using a rubber spatula. Fold until just distributed — do not overmix. Pour the batter over the cooled crust in the springform pan, smoothing the top with an offset spatula.
   Look for The batter is thick and studded with chocolate chunks and shavings evenly throughout.
   Tip Fold in a circular motion from the bottom up to incorporate without deflating the batter.
3. 3Bake the cheesecake
   Place the springform pan in a larger roasting pan and add hot water to come halfway up the sides of the springform. Bake at 350°F (175°C) for 55-65 minutes, until the edges are set and the center is slightly glossy but still moist. The internal temperature should read 160°F (71°C) for the eggs to be fully cooked. Turn off the oven, crack the door, and let the cheesecake cool inside for 1 hour.
   Look for The center should have a slight wobble when gently shaken but not be liquid. The top is lightly golden.

   Tip Do not open the oven during baking. Cooling gradually prevents cracks.

The crust is baked and cooled, and the batter is smooth and creamy with no lumps. The cookie chunks and chocolate shavings are folded in evenly, creating a thick, studded mixture. The batter is poured over the crust and ready for the oven. The kitchen smells of vanilla and chocolate. The cheesecake is now baking in the water bath.

Ganache and Topping

4. 4Make the ganache
   While the cheesecake cools, place the finely chopped 70% dark chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until it just begins to simmer. Pour the hot cream over the chocolate and let it sit for 2 minutes. Stir gently with a spatula until smooth and glossy. Set aside to cool slightly until it thickens but is still pourable.
   Look for The ganache is smooth, shiny, and coats the back of a spoon.
   Tip If the ganache is too thick, whisk in a splash of warm cream. If too thin, let it cool a few more minutes.
5. 5Pour ganache over cheesecake
   Once the cheesecake has cooled to room temperature, remove the springform ring. Place the cheesecake on a serving plate. Pour the slightly cooled ganache over the top, using an offset spatula to spread it evenly to the edges. Allow the ganache to set at room temperature for about 15 minutes, then refrigerate for at least 2 hours until firm.
   Look for The ganache is spread in an even layer, slightly dripping over the sides in places.
   Tip For clean slices, chill the cheesecake thoroughly before cutting.
6. 6Whip the cream
   In a chilled bowl, beat the cold heavy cream and confectioners' sugar with an electric mixer on medium-high speed until stiff peaks form. Be careful not to overwhip — the cream should be thick and hold its shape. Transfer to a piping bag fitted with a star tip.
   Look for The whipped cream forms firm peaks that hold their shape when the whisk is lifted.
   Tip Chill the bowl and beaters for 10 minutes before whipping for best volume.
7. 7Pipe cream and decorate
   Pipe whipped cream peaks around the top edge of the cheesecake, spacing them evenly. Press the halved chocolate cookies around the outside edge of the cheesecake, gently pushing them into the cream and ganache so they stick. Refrigerate the decorated cheesecake for at least 30 minutes before serving.
   Look for The cream peaks are tall and distinct, and the cookies stand upright around the sides.
   Tip Use a small offset spatula to help position the cookies if needed.

The baked cheesecake has cooled completely. The ganache is glossy and pours smoothly over the top, spreading to the edges. The whipped cream is stiff and pipes into tall peaks.

The cookie halves are pressed around the sides, creating a decorative border. The cheesecake is chilling in the refrigerator, and the ganache is setting to a shiny finish.

Slicing and Serving

8. 8Slice and serve
   Use a sharp knife dipped in hot water and wiped dry to slice the cheesecake into wedges. Lift each slice with a metal cake server, revealing the tall layers of crust, creamy filling, cookie chunks, ganache, and whipped cream. Serve chilled.
   Look for Each slice shows distinct layers: cookie crust, dense cheesecake with chocolate chunks, glossy ganache, and cream peaks.
   Tip For clean cuts, clean the knife between slices.

The cheesecake is fully chilled and firm. A knife dipped in hot water cuts clean slices, each revealing the layers of crust, creamy filling with chocolate chunks, ganache, and cream. The slices are lifted with a metal server, holding their shape perfectly. The presentation is tall and elegant, ready to serve.

Common mistakes

Overmixing the batter after adding eggs can incorporate too much air and cause cracks during baking. Skipping the water bath can lead to a dry, cracked cheesecake.

Pouring hot ganache over a warm cheesecake will cause it to melt and slide off — always cool the cheesecake completely first. Overwhipping the cream can turn it grainy and buttery. Also, be sure to chop the cookies into chunks, not crumbs, to keep the intended texture.

How to tell it’s done

The cheesecake is done when the edges are set and the center is slightly glossy and moist — it should have a gentle wobble when the pan is shaken, but not be liquid. For food safety, the internal temperature should read 160°F (71°C) in the center, ensuring the eggs are fully cooked.

After turning off the oven, leave the cheesecake inside with the door ajar for 1 hour to cool gradually, which helps prevent cracking. The ganache is ready when it is smooth and coats the back of a spoon. The whipped cream holds stiff peaks.
