Heat the oven to 325 degrees F. Butter an 8-inch square baking pan.
In a heavy saucepan, melt the chocolate with the butter over low heat, stirring
until completely melted. Remove from the heat and stir in the sugar. Add eggs and
vanilla extract and "beat it all like mad." Stir in the flour, salt and
walnuts and mix well.
Spoon the batter into the prepared pan and bake for 40 minutes.
Take it out; let it cool; cut into squares and go crazy.
