In a large saucepan, heat 1 ½ cups water, cinnamon stick and cloves over medium heat. Bring to a boil and add rice. Continue to boil until most water has been absorbed and rice is tender but not dry.
Add milk, Coffee mate natural bliss Creamer and cornstarch; decrease heat to medium-low and stir until mixture begins to simmer. Add sugar and continue to stir for 5 minutes. Remove from heat and let cool. Mixture will thicken.
