Pre-heat your oven to 350 degrees.
In a large bowl, mix the 4 cups of oats with nuts/seeds, melted coconut oil, and maple syrup. Mix well so that all the oats are coated.
Add the remainder of the ingredients to the bowl.
Line a cookie sheet with parchment paper. To the lined cookie sheet, add the granola mixture. Spread it in a single layer.
Bake it for 15 minutes in a pre-heated 350 degree oven. After 15 minutes, give it a stir and lower the temperature to 300 degrees. Bake for another 20 minutes. More if it's still moist.
Once it is done, let it cool for at least 30 minutes. This will make sure it becomes crispy.
