Preheat oven to 300 degrees. Line large baking sheet with parchment paper.
Mix oats, pecans, almond flour, pumpkin pie spice, cinnamon and salt in large bowl.
In separate microwave-safe bowl, combine maple syrup, oil, brown sugar and vanilla. Microwave in 20 second intervals {mixing in-between} to dissolve brown sugar.
Pour over oat mixture and mix together with rubber spatula, until everything is evenly coated.
Spread granola onto prepared baking sheet. Bake 30 minutes, stirring every 10 minutes. Remove from oven when golden brown.
Do not stir granola. Cool completely in pan. Store granola in airtight container.
