Add all ingredients (except the butter) into the inner pot and stir evenly to distribute the sugar and spices amongst the rice and milk.
Close the lid of the rice cooker and select ‘Congee/Soup’. Press Start.
One hour later, your rice cooker will chime. Open the lid and add in a knob of butter. Stir to melt through.
Remove the spices from the rice pudding and serve warm with a dusting of cinnamon powder (optional) or distribute into individual bowls and chill in the fridge to serve cold.
