I use one cup of low-fat chocolate milk, 2 bananas which I peeled, broke into pieces and froze, and ice. Then, blend til smooth. It comes out really thick, almost like a "real" milk shake, and is so delicious I have to up the quantity of ingredients because DH always wants some. Oh, yeah, I may also add some cinnamon to the mixture because I love chocolate and cinnamon and I learned from Christine on a food channel that cinnamon makes the chocolate taste more chocolate-y.
