In a large bowl, mix the oats, buckwheat, and cocoa powder.
Add the date syrup, and stir until everything is evenly coated.
Line a baking sheet with a nonstick mat or parchment paper and pour the granola onto the sheet, spreading it into an even layer, then bake for 12 minutes.
Carefully sprinkle the coconut over the pan, and bake for another 8 minutes.
Allow the granola to cool for 1-2 hours on the counter - this is when it will get crunchy!
