To make the granola, preheat the oven to 300 degrees and line a baking sheet with parchment paper.
Combine the rolled oats and pecans in a large bowl.
In a separate bowl, whisk together the canola oil, maple syrup, and pumpkin pie spice. Pour the mixture over the oats and stir to combine.
Spread the mixture over the prepared baking sheet.
Bake for 20 minutes, stirring halfway through the cook time.
Remove the baking sheet from the oven and place on a wire cooling rack to cool completely.
Prepare the cheesecake filling by beating together the cream cheese, pumpkin, sugar, and pumpkin pie spice until smooth and well combined.
Fold in the whipped topping.
When the granola is cool, spread an even layer in the bottom of each jar.
Pipe a layer of pumpkin cheesecake over the top of the granola.
Add another layer of granola to the jar, then another layer of pumpkin cheesecake.
Chill for at least one hour before serving.
