4 cups semisweet chocolate chips
1 cup butter or margarine (softened)
1 cup packed brown sugar
1 teaspoon vanilla extract
2 eggs
2 1/2 cups all-purpose flour
1 1/2 teaspoons baking soda
1/2 teaspoon salt
1 (6 ounce) package white baking bars — cut into 1/4- to 1/2-inch chunks
1 cup pecan or walnut halves
Heat oven to 350º. Heat 1 1/2 cups of the chocolate chips in 1-quart saucepan over low heat, stirring constantly, until melted. Cool to room temperature, but do not allow chocolate to become firm. Beat butter, brown sugar and vanilla in large bowl with electric mixer on medium speed until light and fluffy. Beat in eggs and melted chocolate until light and fluffy. Stir in flour, baking soda and salt. Stir in remaining 2 1/2 cups chocolate chips, the white baking bar chunks and pecan halves. Drop dough by level 1/4 cupfuls or #16 cookie/ice-cream scoop about 2 inches apart onto ungreased cookie sheet. Bake 12 – 14 minutes or until set. Cool 1 – 2 minutes; remove from cookie sheet to wire rack.
