In a small saucepan, combine the brown sugar, butter and water. Cook and stir over medium heat until sugar is dissolved. Remove from the heat; stir in the chocolate chips until melted and smooth. Transfer to a large mixing bowl; cool slightly.
Add eggs, one at a time, beating well after each addition. Combine the flour, baking soda, and salt; gradually add to chocolate mixture. Drop by rounded teaspoonfuls onto greased baking sheets. Bake at 350 degrees for 8-10 minutes or until set. Remove to wire racks; flatten slightly. Cool completely.
