Set the oven to 300F / 150C
Line a baking/cookie sheet with foil or greaseproof paper.
Measure out 1 T and 2 t Nutritional Yeast powder - measured out in separate containers.
Pour the Cashews into a saucepan.
Put the marmite, onion powder, garlic powder, 1 T nutritional yeast, sugar and Old Bay Seasoning (if using) into a small jug and pour in the water.
Mix thoroughly.
Turn the heat on the stove to medium and add the olive oil to the cashews.
Heat for about 2 minutes, stirring.
Remove from the heat and stir in the marmite mixture, until all the nuts are evenly coated.
Remove the pan from the heat and spread the nuts out on to the tray and place in the oven.
Bake for about 10-12 minutes, keeping an eye that the nuts don't start to burn.
Remove from the oven, cool for 2 minutes and then sprinkle FIRST with 1 t nutritional yeast.
Stir to coat and leave until cool.
When cold, put into a plastic bag and add the other teaspoon nutritional yeast. Close the mag and mix to combine. Now the cashews are cold this powder will not absorb into the nuts, but leave a powdery coating
When cool store in an airtight container for about a week. If refrigerated, the nuts will keep for up to 2 weeks.
