Cream Cheese and Sugar: Using an electric whisk, beat the room temperature block-style cream cheese and sugar until smooth and creamy.
Add Pumpkin: Incorporate the pumpkin puree, ensuring it is well blended with the cream cheese mixture.
Add Eggs and Flavor: Beat in the eggs, one at a time, followed by the vanilla extract and pumpkin pie spice.
Pour and Smooth: Pour the cheesecake mixture over the pre-baked crust, smoothing the top with a spatula.
Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until the cheesecake is set but still slightly jiggly in the center.
Cool and Chill: Allow the bars to cool to room temperature for 4-6 hours to prevent cracking. Once cooled, move to the fridge to finish setting.
