Measure rolled oats and coconut flakes into a large mixing bowl.
In a small pot, measure out honey and butter (or coconut oil).
Warm honey and butter on the stove until just melted.
Whisk in salt and cinnamon to combine.
Pour contents of the pot over oats and coconut, mixing until everything is sticky and coated.
Dump oats into two, 13x19 inch baking pans and evenly spread.
Space oven racks, placing one on the bottom and the other, on the 3rd rung (unless you have a confection oven; if so you don't have to do this for even toasting).
Slip filled baking pans into the oven and set timer for 7 minutes.
When your timer goes, remove pans from oven and stir golden oats under, bringing fresh oats to the top.
Switch pans, place the top one on the bottom rack and the bottom one on the top. If you don't have a confection oven, this will help evenly roast the granola.
Set timer for another 5-7 minutes.
Remove pans, stir granola again and once again, switch pans around.
Set timer for another 5 minutes.
Granola should be turning a golden brown at this point.
If it still seems raw or looks like it hasn't turned lightly golden in color, return it to the oven for another 5 minutes (max) before removing from oven.
Note: you may overdo your granola the first time. Some ovens are hotter than others, so keep a careful eye on your granola and take notes, so you can get it right the next time 'round!
When your granola is finished, stir in nuts, dried fruit or toasted seeds.
Let granola cool until it reaches room temperature.
Jar and store at the back of your kitchen counter, or you can freeze your granola immediately.
