In a medium bowl, sift flour, baking powder, baking soda, cinnamon, pumpkin pie spice, ginger, nutmeg, and salt. Set aside. On a dinner plate, spread the pumpkin puree. Use 8 sheets of paper towels, use 2 at a time and press into the puree. Do this 4 times to soak up some of the moisture.
2 cups All-purpose flour, 1 tsp Baking powder, 1/2 tsp Baking soda, 2 tsp Ground cinnamon, 1 tsp Pumpkin pie spice, 1/2 tsp Ground ginger, 1/4 tsp Ground nutmeg, 1/2 tsp Salt, 15 oz Pumpkin puree can
Using a mixer, mix the oil, brown sugar, vanilla, sour cream, and pumpkin puree. Add in the dry ingredients and mix on low speed until just combined. Scrape the bowl.
1/2 cup Oil, 3/4 cup Brown sugar, 1 tsp Pure vanilla extract, 1/2 cup Sour cream, 1 Large egg
Spread 1/3rd of the pumpkin batter on the bottom layer of the pan (this will act as the crust). Use a large cookie scoop to scoop half of the cheesecake batter on top of the pumpkin. Use half of the remaining pumpkin batter and scoop on top of the cheesecake batter. Use a butter knife to swirl it together. Repeat with the remaining cheesecake batter and pumpkin batter and swirl it on top.
Bake for 55-65 minutes. The edges will be set and the middle will have a slight jiggle. No water bath needed. The cake will crack due to the cake rising and pushing through the cheesecake.
Turn off the oven, prop open the door, and let cool for 20 minutes. Take out of the oven and place pan on a wire rack. Don't take off the pan until after the chill time. Cool the cake completely before covering with foil. Chill in the fridge for at least 6 hours or overnight.
