I use my rice cooker. I have a ten cup cooker, but usually only make 2 cooked cups of steel cut oats. I've found that spraying nonstick spray (even though the rice cooker is nonstick) and the small amount keeps it from boiling over. I also use about 50 per cent more water than the recipe calls for (I think soaking overnight somehow requires more water) I set the timer to cook it overnight so it's ready when I wake up. I don't have a porridge setting, I use the brown rice setting. When it's done in the morning I mix in ground flaxseed (I don't like to cook the flaxseed) and whatever else I want to mix in (sometimes a mushed banana, sometimes nuts, etc).
