To make the Cereal: For each serving, add ½ cup dry cereal mix to 1½ cups of water. Bring the water to a boil in a saucepan. Add cereal; cover, reduce heat and simmer 15 minutes, stirring occasionally.
Uncover and cook for 2 minutes or until thick, stir constantly. Stir in the sweetener (if using) and serve immediately.
