Preheat oven to 325°F and grease or line one baking sheet with parchment paper.
In the largest bowl you can find, add the rolled oats, coconut flakes, pecans, almonds, sunflower seeds, pumpkin seeds, and sea salt. Set aside.
In a smaller bowl mix the maple syrup, honey, coconut oil (or melted butter) and vanilla extract.
Pour the wet mixture over the dry ingredients and stir well until everything is evenly coated.
Spread the granola onto the prepared baking sheet in an even layer. Use a spatula, the back of a spoon, or your hands to press it down firmly. This helps create the clusters.
Bake for 25–30 minutes, until lightly golden on top and slightly darker around the edges. For larger clusters, do not stir the granola while baking.
Remove from the oven and let the granola cool completely on the pan. This is where it crisps up and forms clusters.
Once fully cooled, break into clusters and store in an airtight container like a large mason jar for 2 weeks or freeze for up to 3 months.
You can use melted butter in place of the coconut oil for a richer, more golden granola with a slightly deeper flavor.
Use coconut flakes for the best flavor and texture. Shredded coconut will work in a pinch, but it can burn easily, so it’s best added halfway through and watched closely.
Don't stir the granola during baking if you want to create clusters.
Swap the nuts and seeds based on what you have; just keep the total amount about the same.
Let the granola cool completely before storing, it crisps up as it cools.
Optional add-ins, if you want to change it up:
Dried cranberries, blueberries, raisins, or chopped apricots (stir them in after baking).
Chocolate chips (add after the granola has cooled).
A sprinkle of cinnamon or a pinch of nutmeg (1/2 to 1 teaspoon cinnamon and 1/8 to 1/4 teaspoon nutmeg).
A handful of chopped dates, a naturally sweet option.
