Preheat oven to 300° F. Line a large baking sheet with parchment paper or a silicone baking mat.
In a large bowl, combine the oats, hazelnuts, cocoa powder, instant coffee, and sea salt and stir. Set aside.
In a medium bowl, whisk together the coconut oil, maple syrup, and vanilla extract. Pour the wet mixture over the dry ingredients and stir to combine. Make sure you even combine everything.
Spread the granola onto the prepared baking sheet and sprinkle with chia seeds if desired. Bake for 45 minutes, stirring every 15 minutes. Once you take the granola out of the oven, allow it to cool completely. Store granola in an airtight container at room temperature for up to 3 weeks.
