Preheat oven to 300F/150C
Line a baking tray with baking paper or a silicone baking sheet
Add all the dry ingredients to a mixing bowl.
Add the maple syrup and miso to a small pan and heat gently using a rubber spatula to mix the miso evenly into the syrup.
Pour the syrup mix over the dry ingredients and mix thoroughly to combine.
Spread onto the baking sheet and smooth out evenly into a thin layer. Dipping a spatula into water stops the mix sticking and makes it easier to spread evenly.
Bake for 20 minutes then turn the tray and bake for a final 10 minutes.
Cool completely before breaking into pieces.
Store in an airtight container at room temperature.
