- 1 Oreo Cookies (24 cookies / 2 cups crumbs)
- 1 Unsalted Butter (4 tbsp / 60g)
- 1 Salt (pinch)
Step 1: The Double-Baked Crust
Preheat your oven to 350°F (175°C). Pulse the whole Oreos in a food processor until fine crumbs form. Mix with melted butter and salt. Press firmly into a 9-inch springform pan.Step 2: The Gentle Emulsion
Reduce oven temperature to 325°F (160°C). In a stand mixer with a paddle attachment, beat the room-temperature cream cheese and sugar on medium-low speed until smooth (about 3 minutes). Scrape the bowl. Add sour cream and vanilla.Step 3: The Egg Integration
Add eggs one at a time, mixing on low speed just until the yolk disappears. Stop mixing immediately after the last egg. Gently fold in the chopped Oreos by hand using a spatula.Step 4: The Water Bath (Bain-Marie)
Wrap the bottom of your springform pan in triple layers of heavy-duty foil (or use a silicone liner). Place it in a large roasting pan. Pour the batter over the crust. Fill the roasting pan with boiling water halfway up the sides of the cake pan.Step 5: The "Slow-Cool" Technique
Bake for 60-70 minutes. The center should still jiggle like gelatin. Turn the oven off, crack the door open 1 inch, and leave the cheesecake inside for 1 hour. Then, remove and chill in the fridge for at least 5 hours. Top with chocolate ganache before serving.Actionable Tip: Use the flat bottom of a glass to compress the crust. Bake for 10 minutes. This "blind bake" seals the crust, preventing it from becoming soggy when the wet batter is added.NLP Note: Do not use a whisk! Whisking incorporates air bubbles, which are the #1 cause of cracks. We want a dense, creamy emulsion, not a fluffy soufflé.Why by hand? This prevents the cookies from bleeding into the batter, ensuring your Oreo Cheesecake has distinct black-and-white specks rather than looking grey.Science Check: The water buffers the heat, keeping the baking temperature gentle and even. This prevents the proteins from tightening too fast, which causes a rubbery texture.
