Combine all ingredients except cinnamon and thoroughly mix with a spatula.
Chill for 30 to 60 minutes.
Using your hands, roll into large marble-sized balls (form a total of 24 balls). Place balls on a plate or flat tray. Return to the refrigerator for 15 minutes.
Sprinkle ground cinnamon lightly over the balls. Using your fingers, gently pat the cinnamon over the surface.
