Step 1: Preheat your oven to 350°F (175°C) for even baking.
Step 2: In a large mixing bowl, combine rolled oats, raw nuts, flaxseed meal, kosher salt, ground cinnamon, and pumpkin pie spice (if using). Stir well.
Step 3: In a separate bowl, whisk together pure maple syrup (or honey), melted coconut oil (or olive oil), whisked egg white, and vanilla extract until blended.
Step 4: Pour the wet mixture over the dry ingredients and fold gently until coated.
Step 5: Stir in the coconut flakes, dried fruit, and chocolate chips if using. Mix until well incorporated.
Step 6: Spread the mixture evenly onto a lined baking sheet, pressing down slightly to create clumps.
Step 7: Bake for 20-25 minutes, stirring halfway through, until golden brown and fragrant.
Step 8: Allow to cool completely on the baking sheet, then break into clusters and transfer to an airtight container.
