Preheat the oven to 160C (140C fan). Line your biggest baking tray with baking paper.
In a large bowl stir together the oats, coconut flakes, seeds, cinnamon and salt.
Melt the coconut oil in a small saucepan over a low heat. Pour the melted coconut oil, maple syrup and vanilla extract over the oat mix and stir to combine.
Tip on to the baking sheet and place in the oven for 15 minutes. Don't stir it during this time. Remove from the oven, turn the baking tray and return to the oven for another 15 minutes so it cooks evenly. Check it every now and then to make sure it doesn't burn.
Remove from the oven and leave to cool for 10 minutes. Then break up in to large clusters. Transfer to a sealed container (I use a large kilner jar) until ready to serve.
