Combine the rolled oats, flour, coconut, brown sugar, cinnamon and salt in a large bowl and whisk to combine well. Break up any lumps of brown sugar.
Place the butter, honey and water in a small saucepan and place over a low heat until the butter is melted. Don’t allow to simmer. Add the baking soda and whisk well. It will foam up a little – this is fine. Add to the dry mix and stir until thoroughly combined.
Roll heaped tablespoons into balls and place on a tray with enough space between each ball for some spreading. Repeat with the remaining cookie dough. Use hand or a fork to lightly flatten.
Bake for 15-18 minutes until desired cooking level has been achieved. Longer will give a crunchier cookie.
Leave on the tray to cool before moving.
Once completely cool, can be stored in an airtight container for a couple of weeks.
