1 1/2 c. all-purpose flour
1 tsp. baking soda
1/2 c. salted butter
1 1/2 c. white sugar
3 c. (18 oz.) semi-sweet chocolate chips
1 tbsp. pure vanilla extract
4 tbsp. hot water
4 lg. eggs
1 c. (6 oz.) white chocolate chips

Preheat oven to 325 degrees. Grease a 9"x13" baking pan.

In a medium bowl combine flour and soda with a wire whisk and set aside.

In a small saucepan melt butter and 2 cups of the semi-sweet chips over low heat, stirring constantly until smooth.

In a large bowl with an electric mixer at medium speed, beat chocolate mixture and sugar until smooth, about 5 minutes. Continuing to beat, add the vanilla, then the water, a tablespoon at a time. Scrape down sides of bowl. Next, add eggs one at a time, mixing well after each addition.

Gradually add the flour mixture, blending at low speed. Then add the remaining 1 cup of semi-sweet chips and the white chocolate chips. Blend until equally distributed throughout batter.

Spread batter into prepared baking pan. Bake 35 to 40 minutes or until toothpick inserted in center comes out just slightly moist.

Cool to room temperature. Cover well and refrigerate until cold. Cut into bars to serve. Yield: 18 servings.
