Add about 1/3 of the pumpkin cake batter to the bottom of the greased Bundt pan.
Pour 1/2 of the cheesecake batter over the pumpkin batter (try to avoid having the cheesecake batter touch the edges of the pan - but it's okay if it does).
Pour another 1/3 of the pumpkin cake batter over the cheesecake batter. Gently spread the pumpkin batter to cover all of the cheesecake batter (do so carefully as to not mix the two together too much).
Pour the remaining cheesecake batter over the pumpkin batter.
Finally, spread the remaining pumpkin batter over the top of the cheesecake batter, spreading it gently to cover all of the cheesecake batter. Tap the pan gently on the counter a few times to release any air bubbles.
Bake for 50-60 minutes or until a toothpick comes out clean.
Once you remove the cake from the oven, allow it to cool right side up for 15 minutes. After 15 minutes, turn the Bundt pan upside down on to a cooling rack to remove the cake from the pan. **it's important that you remove the cake from the pan while it's still warm, but not immediately upon removing it from the oven**
Allow the cake to cool completely to room temperature.
