Pre-heat the oven to 200°C (400°F) and line a large, flat baking tray with grease-proof paper.
Heat the maple syrup, peanut butter and butter together in a pan, just until the butter has melted.
In a large bowl, mix up all the other ingredients until combined.
Pour the warm ingredients over the dry, and stir together (you may need to get your hands in to ensure the dry ingredients are well coated).
Sprinkle the granola over the prepared tray, moving it around with your hands to make sure no bits are on top of each other.
Bake in the oven for between 5-10 minutes until nice and golden. Watch very carefully as it can turn from perfect to burnt in a matter of seconds (and believe me, I speak from miserable experience).
Allow to cool and then enjoy it as breakfast or sprinkled over a little Greek yoghurt.
