Preheat Oven: Heat oven to 300°F (150°C). Line a large baking sheet with parchment paper.

Combine Dry Ingredients: In a large mixing bowl, mix rolled oats, mixed nuts, shredded coconut (if using), ground cinnamon, and sea salt.

Prepare Wet Mixture: In another bowl, whisk together honey or maple syrup, melted coconut oil, and pure vanilla extract.

Mix Together: Pour the wet mixture over the dry ingredients and stir until everything is evenly coated.

Bake: Spread the mixture evenly on the prepared baking sheet. Bake for 21 to 24 minutes, stirring once halfway through, until the granola is golden brown.

Cool: Allow the granola to cool completely on the baking sheet; it will become crisp as it cools.

Store: Once cooled, store the granola in an airtight container at room temperature for 1 to 2 weeks or in the freezer for up to 3 months.
