In a large bowl, combine butter and brown sugar until crumbly, about 2 minutes. Beat in egg. Gradually beat in coffee. Combine the flour, baking powder, cinnamon, baking soda and salt. Gradually add to the coffee mixture until blended. Stir in raisins and pecans.
Transfer to a 13x9-in. baking pan coated with cooking spray. Bake at 350° for 18-20 minutes or until edges begin to pull away from the sides of the pan and a toothpick inserted in the center comes out clean. Cool on a wire rack for 5 minutes.
Meanwhile for icing, in a small bowl, combine the confectioners' sugar, vanilla and enough water to achieve spreading consistency. Spread over warm bars.
