Deirdre's Chocolate Lovers Brownies

I have tried dozens of brownie recipes over the years and I finally got
one that has the right flavor and the right consistency.  Many thanks to
Deirdre Christman for this fool-proof (it worked for me!) and easy one..

Ingredients:

2 sticks of unsalted butter
4 squares of unsweetened chocolate
2 cups sugar (I like a tad less)
4 eggs (if they are jumbo use only 3)
1 cup flour
pinch salt
1/2 teaspoon vanilla
1 cup chocolate chips
1 cup walnuts (optional)

Technique:

Melt butter and chocolate slowly in a pot large enough to hold all of
the ingredients.  Cool slightly then add sugar and then beat in one egg
at a time.  Then add vanilla and all of the rest of the ingredients,
mixing enough just to blend the flour.

Spread evenly into a greased 9 X 13 pan and bake in a pre-heated 350 degree
oven for 25 minutes.

Cool several hours before trying to cut or remove from pan.
