In a medium bowl, combine the crust ingredients and mix until a thick dough forms.
Press evenly into the bottom of the baking pan.
In large mixing bowl, combine the cream cheese, sugar, and vanilla.
Beat with hand mixers until completely smooth and creamy.
Add in the eggs, one at a time, and beat until each is combined.
Remove 1 and 1/2 cups of this mixture and pour on top of the crust.
Add the pumpkin puree, cinnamon, and pumpkin pie spice to the remaining cheesecake mixture and stir until completely combined.
Careful not to combine the two layers, pour the pumpkin layer on top of the plain cheesecake layer.
Using a medium mixing bowl, stir together the brown sugar, white flour, oats, and cinnamon.
Add in the butter and vanilla and mix together until well combined.
Sprinkle this streusel topping evenly over the pumpkin cheesecake layer.
Place in the oven and bake for 50-55 minutes or until the cheesecake has set.
Allow to cool for about an hour and then place in the fridge for 1-2 hours.
Cut into bars and enjoy!
