Preheat the oven to 180°C. Line two baking trays with baking paper.
Stir the flour, rolled oats, coconut, sugar, orange zest and thyme leaves in a large mixing bowl.
Heat the butter, water and honey in a small saucepan, stirring occasionally until the butter has melted. Remove from the heat, add the bicarbonate of soda and stir to combine (the mixture will foam up).
Add the the butter mixture to the dry ingredients and mix until well combined.
Using an ice cream scoop to measure out evenly-sized amounts of the mixture, roll the portions into balls and place them on the tray with plenty of space between them (they will spread). Flatten them with a fork.
Bake in the oven for 15 minutes, swapping the trays around halfway through cooking.
Remove from the oven and cool on the trays before storing them in an airtight container.
