Spread 3/4 of the cheesecake mixture carefully over the crust. Leave the remaining filling in the food processor.
To the processor, add the pumpkin puree and pumpkin spice. Blend until smooth once again.
1 cup pure pumpkin puree, 1 teaspoon pumpkin pie spice
Add the pumpkin mixture on top, carefully smoothing it out.
Bake, uncovered for 30 minutes.
Crumble:
While the cheesecake is baking, make the crumble. Pulse the walnuts and brown sugar in a food processor until coarsely chopped.
1 cup walnuts, 1/3 cup light Brown Sugar
Add the flour, pumpkin spice, salt, melted butter, and a teaspoon of water. Pulse once more until the mixture forms crumbly bits.
1/2 cup all-purpose flour, 1 teaspoon pumpkin pie spice, 1/4 teaspoon salt, 4 tablespoons unsalted butter, 1 teaspoon water
Scatter the crumble on top of the cheesecake bars (after they have baked for 30 minutes) and bake for an additional 20 minutes or until the crumble achieves a golden-brown hue.
Allow the cheesecake to rest at room temperature until completely cooled. Once it’s cooled, refrigerate for 4 hours before slicing.
Remove the cheesecake from the baking dish, cut into bars, and serve.
Notes
Room Temperature Ingredients: Ensure the cream cheese is softened and at room temperature for a smooth cheesecake filling.
Use Parchment Paper: Line your baking pan with parchment paper, allowing extra to hang over the sides for easy removal.
Don’t Overmix: Mix the cheesecake filling on low speed with a hand mixer or stand mixer to avoid incorporating too much air.
Check for Doneness: Bake until the edges are set, and the center still has a slight jiggle. This ensures a creamy cheesecake.
Cool Gradually: Allow the bars to cool in the pan on a wire rack before refrigerating to prevent cracks.
Sharp Knife: Use a sharp knife to cut the bars, wiping it clean between cuts for neat slices.
