Phase 1: The Galactic Foundation
Preheat oven to 350°F (175°C). Wrap a 9-inch springform pan base with heavy-duty foil.
Pulse Oreo cookies in a food processor until coarse crumbs form (texture like black sand).
Mix crumbs with melted butter; press firmly into pan bottom for a compact crust.
Phase 2: The Cosmic Filling
Beat room-temperature cream cheese on medium for 3-4 minutes until smooth and fluffy.
Gradually add sugar, beat 2 more minutes until lightened.
Add eggs one at a time, mixing just until combined—avoid over-mixing.
Beat in vanilla extract and sour cream until smooth and flowing.
Phase 3: The Water Bath Baking Method
Place springform pan in larger roasting pan; pour filling over crust.
Pour hot water into roasting pan halfway up springform sides.
Bake 50-55 minutes until edges set and center jiggles slightly.
Turn off oven, crack door open, cool cheesecake in oven for 1 hour.
Phase 4: The Cosmic Drip Creation
After chilling overnight, heat heavy cream until simmering; pour over chocolate chips.
Let sit 2 minutes, whisk until smooth and glossy at 80-85°F.
Drip ganache around edges and fill top surface using a squeeze bottle or spoon.
Work quickly; ganache sets in about 5 minutes. Vary drip lengths for a natural cosmic look.
