4 oz. unsweetened chocolate

1/2 C. (1 stick) butter

4 eggs

2 C. sugar

1 C. sifted all-purpose flour

1 t. vanilla extract

1 C. broken walnuts

Preheat oven to 325° F. Grease a 9-by-9-by-2-inch baking pan; set aside.

Melt chocolate and butter in a double boiler or mixing bowl over a pan of hot water; cool slightly. (Alternatively, this can be melted in a microwave, stirring it and watching it carefully to prevent the chocolate from burning.)

Beat eggs until foamy. Gradually add sugar, beating thoroughly after each addition. Blend in chocolate mixture. Mix in flour, then vanilla, then nuts.

Spread in greased pan, smoothing to the corners. Bake about 40 minutes, until brownies begin to pull from sides of pan.

Cool to room temperature in the pan on a wire rack, then cut into squares or bars.

Makes about 2 dozen.
