Preheat oven to 340°F (170°C) and line a large baking sheet with parchment paper..
Pulse the nuts: Add pecans, hazelnuts, almonds and pumpkin seeds to a food processor. Pulse a few times until roughly chopped (you want texture, not nut flour).
½ cup pecans , ½ cup hazelnuts blanched , ½ cup almonds , ⅓ cup pumpkin seeds
Mix the wet ingredients: In a small pan, gently heat coconut oil, maple syrup, vanilla extract, and cocoa powder. Stir until smooth and glossy.
⅓ cup cocoa powder, 4 tablespoon coconut oil , ½ cup maple syrup , 1 teaspoon vanilla extract
Combine: In a large bowl, mix oats and chopped nuts and seeds. Pour the chocolate mixture over the top and stir until everything is well coated.
2 ½ cups cups large flaked rolled oats
Bake: Spread evenly on the baking sheet. Bake for 20 minutes, stirring 2- 3 times to prevent burning and to help it crisp up.
Cool & finish: Let the granola cool completely (it firms up as it cools). Stir in the dark chocolate chips (optional) once cooled completely.
⅓ cup (vegan) dark chocolate chips
Store: Transfer to an airtight jar or container. Keeps well for about 2 weeks.
