Combine all dry ingredients in a large mixing bowl.
Blend the dates and water together then transfer the liquid to a small saucepan. On a low heat, warm the date mixture through for a few minutes until lukewarm. Stir regularly and do not allow to boil. Then stir in the vanilla extract.
Once warm, pour the wet ingredients over the dry ingredients and stir until fully combined.
Spread mixture in a thin, even layer over a baking tray (you may need two). Place in the centre of the oven for 20-25 minutes until granola is golden brown and crunchy.
