4 sticks (1 lb.) butter
8 sq. (8 oz.) Baker's Unsweetened Chocolate
8 eggs
3 c. white sugar
1 c. light brown sugar (tightly packed)
3 c. white flour
2 tsp. baking powder
1/2 tsp. salt
4 tsp. vanilla extract
1 to 2 c. crushed walnuts or pecans, optional

Spray two large roasting pans (15 x 11 x 3 inch) or 3 (13 x 9 x 2 inch) baking pans with Pam Cooking Spray. Preheat oven to 350 degrees.

Melt butter and baking chocolate at medium heat stirring until melted. If you use microwave - set it at medium. Set aside. In large bowl, beat eggs until frothy; slowly add sugars, beating until thickened with electric mixer on medium speed.

Pour in butter and chocolate mixture, while mixer is still running. Mix until well blended. Combine dry ingredients - slowly add to chocolate mixture. When everything is smoothly blended, add vanilla extract, mixing well; add nuts if desired beating mixture by hand.

Pour into prepared pans and bake at 350 degrees for 20 to 25 minutes. (You may want to check pans after 10 minutes and turn them or switch oven shelves to promote even baking.) Makes 7 dozen brownies.
