My Favorite Brownie's

This recipe is from my Betty Crocker's Cooky Cook Book.  And it's headline is:

THE BEST COOKY OF 1920-1930

4 sq. unsweetened Chocolate (4 oz.)
2/3 cup shortening
2 cups sugar
4 eggs
1 tsp. vanilla
1-1/4 cups Gold Medal Flour
1 tsp. baking powder
1 tsp salt
1 cup chopped nuts

Heat oven to 350 degrees (mod).  Grease oblong pan  13" x 9-1/2" x 2".  Melt chocolate and shortening over low heat.  Beat in sugar, eggs, and vanilla.  Measure flour by dipping method or by shifting.  Stir flour, poking powder and salt together; blend in.  Mix in nuts.  Spread in pan.  Bake 30 minutes or until brownies pull away from the sides of the pan.  Do not over-bake.  Cool slightly and cut in bars.  Makes 32 brownies.

Note:  If you use Gold Medal Self-Rising Flour, omit baking powder and salt.
