Mocha Bars

Preheat oven to 350 degrees. In a saucepan, melt butter. Add brown sugar and stir until dissolved. Let mixture cool, then beat in egg. Sift together flour, salt and baking powder and add to butter-egg mixture alternately with the cold coffee. Blend in the vanilla and stir in the chocolate chips and nuts.

Note: For neater bar cookies, line the baking pan with foil before greasing. When the bars have finished baking, let them cool a few minutes in the pan. Flip the uncut bars onto a wire rack; remove the foil and let cool completely, then cut into squares. Bars will cut without ragged edges.
