01 - Preheat oven to 325°F (165°C). Line a large, rimmed baking sheet with parchment paper to prevent sticking.
02 - In a large mixing bowl, toss together oats, pecans, pumpkin seeds, coconut (if using), salt, cinnamon, ginger, nutmeg, cloves, and allspice until thoroughly mixed.
03 - In a separate bowl, whisk pumpkin purée, maple syrup, melted oil, and vanilla extract until fully unified and smooth.
04 - Pour the wet mixture over the dry ingredients. Stir with a spatula until every oat is evenly coated.
05 - Evenly spread the granola mixture onto the prepared baking sheet. Pat down gently to form clusters. Bake for 30–35 minutes, stirring once at the midway point, until golden and aromatic.
06 - Remove granola from oven and let it cool completely on the pan; it will crisp as it cools. Once fully cooled, stir in dried cranberries and crystallized ginger (if using). Transfer to an airtight container for storage.
