Preheat oven to 180 degrees C. Grease a 20x30cm pan.
In a large bowl combine flour, white sugar, bicarb soda, cinnamon, ginger, cloves, salt, coffee, butter, molasses and eggs. Beat 2 minutes at medium speed. Pour into prepared pan.
Bake for 25-30 minutes. Let cool.
To Make icing: In a small saucepan over low heat cook 1/3 cup butter until light golden brown, stirring constantly. Add icing sugar, vanilla and water. Blend until smooth (may need to add more water). Spread over cooled bars.
