Preheat oven to 300°F (150°C).

Coat a cookie sheet with nonstick cooking spray.

In a large mixing bowl, combine rolled oats, chopped almonds, chopped pecans, shredded coconut, pumpkin pie spice, and cinnamon.

Mix dry ingredients until well combined.

In a separate bowl, whisk together maple syrup, brown sugar, canned pumpkin, and vanilla extract.

Pour the wet mixture over the dry ingredients.

Stir until all ingredients are evenly coated.

Spread the granola mixture in a thin, even layer on the prepared cookie sheet.

Bake for 30-35 minutes, or until lightly golden brown, stirring halfway through to prevent burning.

Remove from the oven and let cool on the cookie sheet for at least 5 minutes.

Transfer the granola to a large bowl and mix in dried cranberries.

Once completely cool, store the pumpkin spiced granola in an airtight container.
