Pre-heat the oven to 325 degrees. Combine all ingredients in a large bowl. Mix really well, making sure everything is evenly coated with maple syrup and coconut oil. I usually use my hands to do this.
Line a large sheet tray with parchment paper and pour the granola mixture onto it in one even layer. Bake for 20 minutes, then remove the tray from the oven and stir with a wooden spoon or spatula. You will notice the corners and edges start to brown first, so make sure to move the granola around so that it does not burn. Return the tray to the oven and cook for another 10 minutes or until the granola is evenly golden brown and fragrant.
Let the granola cool completely before eating. Store in an airtight container for up to two weeks!
