brownies, as they should be

This recipe has numerous rave reviews, and why shouldn't it?  It's incredibly easy, requires simple ingredients, and the batter tastes amazing (I admit...I cheated on my diet plan and licked the bowl).  The brownies have that absolutely perfect crust that I've never seen on anything but a boxed recipe.

Brownies, As They Should Be
From Tasty Kitchen's rainydaygal

• 1 1/2 cup flour
• 1/2 t. baking soda
• 1/2 t. salt
• 1 1/2 cup sugar
• 2/3 cup butter
• 4 T. water
• 2 packages (12 oz.) chocolate chips, divided
• 2 t. vanilla
• 4 eggs
• 1 cup chopped walnuts (optional)

Preheat oven to 375 degrees.  Mix together flour, baking soda, and salt; set aside.  In a large saucepan, melt butter with sugar and water; remove from heat.  Add one package of chocolate chips and vanilla, stirring until chocolate chips have melted.  Add eggs, one at a time, mixing well in between each.  Stir in flour mixture and then fold in remaining chocolate chips and walnuts.  Bake for 30-40 minutes, or until a toothpick comes out clean.  Let cool for at least 2 hours before serving.
