In a large mixing bowl, combine all of the dry ingredients, stirring well to ensure everything is evenly distributed.
In a separate bowl, whisk together all of the wet ingredients until fully combined.
Pour the wet ingredients over the dry ingredients and mix thoroughly until all of the oats, nuts, and seeds are evenly coated.
Transfer the granola mixture to the prepared baking tray and spread it out into an even layer. Gently press the mixture down with the back of a spoon or spatula to encourage those delicious granola clusters to form.
Bake for 45 minutes at 150 degrees, or until golden brown and crisp. Check the granola halfway through cooking and gently turn it if necessary to ensure even baking.
Once baked, remove the tray from the oven and leave the granola to cool completely on the tray. This step is essential, allowing the granola to cool undisturbed helps create the large crunchy clusters that make homemade granola so irresistible.
When completely cool, break the granola into chunks of your desired size and transfer to an airtight container.
