Chocolate Custard

8 egg whites
2 cups chocolate-flavored low-fat milk
1/4 cup sugar
1 teaspoon vanilla

In a large mixing bowl use a fork or wire whisk to lightly beat egg whites. Stir in milk, sugar, and vanilla. Place six 6-ounce custard cups in a 13x9x2-inch baking pan on an oven rack. Pour milk mixture into the custard cups. Pour boiling water into the pan around the custard cups to a depth of 1 inch. Bake in a 325 degree oven for 25 to 35 minutes or till a knife inserted near the center comes out clean. Serve warm or chilled.
