4 (1 ounce) squares unsweetened chocolate
3/4 cup butter
2 cups white sugar
1 teaspoon vanilla extract
1 cup all-purpose flour
1 cup chopped walnuts
chocolate chips (optional)
1. Preheat oven to 350 degrees.
2. Microwave chocolate squares and butter in a large bowl on HIGH for about 1 minute (or until butter is melted). Stir until chocolate is melted.
3. Add sugar and mix. Stir in the eggs and vanilla. Mix in the flour and nuts. At this point I tossed in a few handfuls of semi-sweet chocolate chips.
4. Spread batter into a greased 9×13″ pan. Bake for 33-35 minutes. Do not over bake.
