Place milk, egg, sugar, salt, vanilla and cinnamon in a bowl and whisk to combine.
Divide milk mixture between 2 x 350ml microwave-safe mugs. Using a fork, separate rice in one tub. Add to one mug. Repeat with remaining rice and mug.
Microwave one mug on 30% power for 6 minutes or until mixture thickens and rice pudding is set (see recipe notes). Repeat with remaining mug. Stand for 2 minutes before serving dusted with a little extra cinnamon.
