Combine sugar and water in a medium saucepan; cook over low heat, stirring constantly, for 3 to 4 minutes or until sugar is dissolved. Increase heat to medium-high, boil, without stirring, for about 15 minutes or until caramel-colored. Quickly pour over bottom and sides of twelve 6 ounce ramekins or custard cups (if syrup hardens, soften over low heat.).
Heat evaporated milk in a small saucepan until it begins to simmer. Remove from heat. Stir in chopped chocolate until melted.
