Pre-heat your oven to 180 degrees Celsius. Prepare a baking tray with parchment or a silicone mat.
In a large bowl, mix your oats, whole nuts, seeds, cacao powder, cinnamon. Add your coconut oil, pure honey or maple, vanilla, and sea salt. Mix with a large spoon or by hand. Transfer granola on to the baking tray and using a spatula, press down the granola against the tray so this crisps it up nicely.
Bake for a total of 20-25 minutes. Halfway through (after 10 minutes), take out the tray and flip the granola using a flat spatula and press it down again. This helps the granola to cook evenly and crisps up into clusters.
Once cooked, take out of the oven and let it cool for about 10 minutes without stirring. Again, this will let it continue to cook and create clusters and more crunch.
Lastly, add your chopped chocolate, and another sprinkle of sea salt. Store in an air-tight container and enjoy!
This can last up to a month in your pantry if stored in a cool, dry place. Otherwise you can also store in your fridge.
