Whisk egg white in a medium bowl until frothy, then add coconut sugar, cinnamon and sea salt and stir until well combined. Add the macadamias and stir through the mixture, ensuring that they are evenly coated.
Add the macadamia mixture to a lined baking tray and place in the oven for 30 minutes, stirring every 10 minutes to ensure that the nuts do not burn. Remove from the oven to cool completely, then break apart.
Store in an airtight jar or container.
