Preheat oven to 170 degrees.
Combine dry ingredients in a bowl and mix.
In a saucepan (or in the microwave) combine the coconut oil, sweetener and milk. Bring to the boil and allow to simmer for 2-3 minutes.
Pour wet mix into dry and ensure that granola is well and evenly coated. Add a small splash of milk if it's too dry. End product should be quite dry but slightly sticky.
Grease a baking tray and spread out mixture in a bit square/circle shape. Try and compact it. Bake for 20 mins (should be golden brown) before loosely breaking into chunks and spreading around the tray. Return to oven for 5-10 more minutes to get extra crispy. Remove and let cool before storing in an airtight container.
