The very best brownies in the world

This is another of my mother, RuthAnn Lavin's, fabulous recipes. I know that you can open a packaged mix and have brownies in about 30 minutes, but you can not have these brownies that fast. And these are worth waiting for!

My sweetheart doesn't like walnuts, so I usually leave the nuts out when making them for the family. But I like them best with the nuts included :-)

The Very Best Brownies in the World

4 eggs
2 c sugar
1/4 t salt

4 oz (4 squares) of unsweetened chocolate
1/2 c butter

1 t vanilla
1 c flour
1 c chopped nuts (optional)

Beat the eggs, sugar, and salt together in a large mixing bowl until thick and smooth. Melt the chocolate and butter together, either in a double boiler or gently in a microwave. Let the mixture cool and stir carefully into the eggs, slowly, beating all the time so the eggs don't curdle. Stir in the vanilla and flour until just combined. Fold in the nuts.

Scrape into a 9 x 13 inch pan and bake at 325 for 40 to 45 minutes. Cool and cut.
