3/4 cup all-purpose flour 1/2 teaspoon baking powder 1/2 teaspoon salt 1/2 cup broken nuts
Preheat oven to 350 degrees Fahrenheit.
Sift together dry ingredients (flour, baking powder and salt), and set aside.
Melt chocolate and shortening in a double boiler (in a pan which is over another pan of boiling water). Remove pan from heat, and beat in the sugar and eggs. Stir in the dry ingredients, and then mix in the nuts.
Spread combined ingredients in a well-greased 8-inch square pan. Bake 30 to 35 minutes, or until top has dull crust. A slight imprint will be left when top is touched lightly with finger. Cool slightly, then cut into squares.
