01 - Preheat the oven to 325°F and line a large baking sheet with parchment paper.
02 - Combine oats, walnuts, coconut flakes (if using), cinnamon, and salt in a large bowl.
03 - Whisk together maple syrup (or honey), melted oil, and vanilla extract in a small bowl.
04 - Pour the wet mixture over the dry ingredients and stir thoroughly until oats are evenly coated.
05 - Spread the granola mixture evenly onto the prepared baking sheet.
06 - Bake for 25 to 30 minutes, stirring halfway through, until golden brown and fragrant.
07 - Remove from oven and let cool completely on the baking sheet; granola will crisp as it cools.
08 - Once cooled, stir in dried cranberries evenly throughout the granola.
09 - Store in an airtight container at room temperature for up to two weeks.
