I use Muscle Milk Vanilla Shake protein powder (from Costco). It does have maltodextrin and sucralose. If you don't like that you could use honey, stevia, xylitol or nothing but the fruit. It's the oatbran mixed in with the oatmeal that gives it a much nicer consistency than plain oatmeal. When I tried cooking steel cut oats, it just took too much time for me.
