In a medium bowl, combine the pumpkin puree, vegetable oil, water, and vanilla. Whisk well.

Generously grease a bundt pan with nonstick spray.
Add 3 cups (675 G) of pumpkin batter to the pan and spread evenly. Then, scoop the cream cheese filling over the batter, making a ring. Top with the remaining batter and spread to cover the filling.

Remove the cake from the oven and let cool for 15 minutes before inverting to remove from the pan.
