Creamy Rice Pudding

In a deep pot melt 1 stick of butter. Add 1 can of condensed milk, stir to combine. Add 2 cups of cooked rice plus 1/2 c raisins and heat until mixture has thickened, about 20 minutes. Remove from heat and add 1 T vanilla. The rice pudding will thicken a bit off the heat. Serve with cinnamon sugar. I like to place the rice pudding in the refrigerator( this also thickens it) and eat it cold.
