Equipment

  • Pressure cooker
  • 8-inch Springform pan
  • Trivet
  • Food processor or electric mixer
  • Aluminum Foil

Ingredients
 

  • 1/2 cup chocolate cookie crumbs
  • 1 pinch ground cinnamon
  • 8 ounces semisweet chocolate
  • 1 tablespoon butter
  • 16 ounces cream cheese softened
  • 1 cup heavy whipping cream
  • 1 teaspoon vanilla extract
  • 2/3 cup white sugar
  • 2 eggs beaten
  • 1 1/2 tablespoons unsweetened cocoa powder
  • 1 1/2 cups water

Instructions
 

Prep the Pan and Crust

  • Grease an 8-inch springform pan that fits your pressure cooker. For easy removal, place a parchment paper round on the bottom. Stir the chocolate cookie crumbs and ground cinnamon together until evenly blended. Press the mixture into the bottom of the pan to create a level, packed layer.

Melt the Chocolate and Build a Silky Batter

  • Melt the semisweet chocolate and butter together until glossy and smooth, then set aside to cool slightly. Beat the softened cream cheese with a mixer or food processor until satiny. Gradually stream in the melted chocolate while mixing until the color is uniform.
  • Incorporate the heavy whipping cream, vanilla extract, white sugar, and beaten eggs. Mix on low speed until the batter is cohesive and shiny. Sieve the cocoa powder over the top and mix gently until no streaks remain. Pour the batter into the prepared pan and tap it against the counter to release air bubbles.

Pressure Cook, Then Cool Slowly

  • Cover the pan with waxed paper and wrap it securely in aluminum foil. Add 1 1/2 cups of water and a trivet to the pressure cooker. Place the pan on the trivet, seal the lid, and cook at high pressure (15 pounds) for 45 to 50 minutes.
  • Once cooking is complete, allow the pressure to release naturally. Carefully remove the pan, unwrap the foil, and let the cheesecake reach room temperature on a wire rack. The edges should be set while the center retains a slight jiggle.

Chill for the Final Set

  • Refrigerate the cheesecake for at least 8 hours before serving. This step is essential for achieving the perfect mousse-like texture and clean, sharp slices.

Notes

The Room Temp Rule: Ensure your cream cheese is truly softened before mixing to avoid white specks in your dark chocolate batter.
The Wobble Test: When done, the edges should be firm but the center should jiggle like set Jell-O. It will fully firm up during the 8-hour chill.
Clean Slicing Tip: For bakery-style slices, dip your knife in hot water and wipe it dry before every single cut.
Waterproofing Safety: Use a double layer of foil around the base and seams of your springform pan to prevent steam or water from making the crust soggy.
