Preheat oven to180°C. Combine oats, nuts, seeds, a pinch of sea salt and cinnamon in a large bowl.
In a separate bowl, combine all the wet ingredients and stir well.
Pour the liquid mixture over the oat’s mixture. Stir really well to ensure all the dry ingredients are moistened.
Spread the mixture in fairly even layer onto a rimmed baking sheet, but with very little, if any, space between the ingredients. This is how you’ll get the nice big clumps of granola!
Bake for 25-28 minutes, shaking the pan and flipping the mixture over as best you can about halfway through.
The granola will continue to crisp up as it sits, so don’t over-bake or it will burn. Add the raisins once the granola is cooked and cooled.
Allow to cool before eating. Store any leftovers in an airtight container to keep it fresh!
