Mom's brownies

The best brownies in existence.  Somehow, it makes a difference who makes them:  Mum's are fudgiest, Amber's were black last time, and Mandy's are generally burnt to a crisp.  Um, good luck, I suppose. (:

















4 sticks butter, melted
scant 2 c. white sugar
1/2 c. cocoa
4 eggs
1 t. vanilla
3/4 t. salt
1 1/2 c. flour

(Chocolate chips and walnuts make delish additions to the top!  Also, I was thinking a toffee crumbled on the top might be nice?  but a bit sweet perhaps.) 
(I added a teaspoon of finely ground coffee, it was tasty.)

Melt the butter in a big bowl in the microwave.  Then add the rest of the ingredients in the order they're listed, stirring after the addition of each.  Bake in a 9x13'' cake pan at 350F until a toothpick inserted in the middle comes out clean.  Cook them for less time for fudgier brownies. MMmmmmmm...
