Preheat oven to 325˚F. Line a baking tray with parchment paper or spray with cooking spray and set aside.
In a large bowl, whisk together pumpkin, sugar, syrup, oil, vanilla, pumpkin spice, cardamom if using, and salt.
Add oats, pecans, and pepitas and toss to coat.
On the prepared tray, spread granola evenly. Bake 20 minutes. Remove from the oven and stir. Add cranberries if using and stir to combine. Bake for 10-20 more minutes, or until lightly browned and oats are crisp, stirring after 10 minutes.
Remove from the oven, stir, and cool completely. The granola will crisp as it cools. Once granola has cooled, break into pieces. Store in a zip top bag or airtight container for 3-4 weeks or in the freezer for 3 months.
