Have you looked at what's in non-dairy creamer?

I make a liter of strong coffee, add one packet of Truvía (to knock down any bitterness), chill it, and mix it (over ice) with a good slug of half-and-half (not ultra pasteurized, milk and cream the only ingredients).

That's what I drink every morning in the summer. When it cools off in the fall, I go back to hot coffee.
