I'm drinking one right now
Here's a link with a recipe -
http://www.ehow.com/how_2293047_make...ed-coffee.html but it requires that you wait overnight which is much too long for me
For mine, I took a cup of plain brewed coffee, 2.5 T of hot chocolate mix, 1 cup of milk (I used rice milk) and a bit of sugar. I mixed it up in a juice mixer pitcher and then added some ice. It melted and so I poured it over some ice in a glass.
The problem was that my first batch of ice melted right away and watered down the coffee. I would let your coffee cool a bit before making it (as hard as that is)
The good part was that I got three glasses of coffee out of it.
You'd have to tweak it how you like it but it's a basic recipe.
