Preheat the oven to 350 degrees F. Line a large rimmed baking sheet with parchment paper.
In a large bowl, mix the oats and pepitas.
In a small saucepan, whisk together the coconut oil, pumpkin, maple syrup, cinnamon, nutmeg, ginger, cloves, and salt. Heat over medium heat, whisking occasionally, until the coconut oil is melted and the mixture is warm. (Alternatively, you can whisk these ingredients in a microwave-safe bowl and then heat for 45 seconds to 1 minute.
Pour this pumpkin mixture over the oats and pepitas and mix well with a spoon. Spread mixture onto your prepared baking sheet and bake until golden brown, 20 to 25 minutes. Remove the pan from the oven and let it cool completely, undisturbed (it will crisp as it cools). Once cool, break the granola into pieces with your hands if you want to retain big chunks, or break it apart with a wooden spoon if you don’t want extra-clumpy granola.
Store in an air-tight container at room temperature for up to 10 days.
