Step 6
Add the pumpkin to the remaining cheesecake batter, and pulse until fully incorporated. Pour the pumpkin cheesecake into the cooled crust. If using, slowly pour the reserved white cheesecake batter over the pumpkin cheesecake batter in a slow, thin stream, and use a toothpick or wooden skewer to swirl the two batters together. (If you pour too quickly, the white batter will sink inside the pumpkin.)
