I make steel cut oats in a rice cooker with a timer, so I can put the oats and water in the night before. I've pre-mixed the spices, peanut powder, flax powder. I throw nuts and raisins in when I mix it all together in the morning. For spices it's cocoa, tiny bit of cloves, tiny bit of cinnamon, tiny bit of ginger, pinch of salt.
Steel cut oats are even better done with chicken broth as a savory in the rice cooker. Use as you would rice with dinner, or break an egg over a bowlful in the morning and microwave or "fried rice" it.
