1Preheat oven 300. In food processor, grind 1 cup oats to a fine powder.
2In a large bowl combine whole oats, ground oats, nuts, coconut, cinnamon & nutmeg.
3In saucepan over medium heat, combine the brown sugar, butter, water, and maple syrup. Heat just until butter has melted and mixture is bubbly. Stir in salt and vanilla.
4Pour hot mixture over the oats mixture, stirring well to coat (I use hands). If not uniformly moist, stir in another tablespoon or two of water. Let mixture stand 10 minutes.
5Spread the mixture out on a large jelly roll baking sheet (I line with parchment paper). Separate granola a little to allow space between for the hot air to circulate. Place pan on center rack and bake for 40 minutes. Remove from oven and stir (I gently flip with a spatula). Return to oven to bake for additional 20 minutes. Stir/flip one more time and bake approximately 15 more minutes until the mixture is uniform golden brown and completely dry.
6Cool completely. Store in a covered container at room temperature.
