Preheat your oven to 300°F (150°C) and line a large rimmed baking sheet with parchment paper.
In a large bowl, combine the oats, pepitas, chia seeds, cinnamon, and salt.
In a small bowl, whisk together the melted coconut oil, honey (or maple syrup), and vanilla extract.
Pour the wet mixture over the dry ingredients and stir until everything is evenly coated.
Spread the mixture onto the prepared baking sheet and press it down firmly with a spatula or the bottom of a measuring cup — this is what creates big clusters instead of loose crumbs.
Bake for 35–40 minutes total, rotating the pan (not stirring) at the 20-minute mark for even color.
Remove from the oven and let the granola cool completely on the pan, undisturbed, for at least 30 minutes.
Once fully cooled, break the granola into clusters and fold in the dried cranberries.
Store in an airtight container at room temperature.
