1 cup granulated sugar
1 1/2 teaspoons vanilla extract
1 teaspoon salt
2 cups all-purpose flour
2 cups (12-ounce package) NESTLÉ TOLL HOUSE Semi-Sweet Chocolate Morsels, divided
1 cup chopped nuts

PREHEAT oven to 375°F. BEAT butter, sugar, vanilla extract and salt in large mixer bowl. Gradually beat in flour. Stir in 1½ cups morsels and nuts. Press into ungreased 15 x 10-inch jelly-roll pan. BAKE for 20 to 25 minutes or until golden brown and set. Cool until just slightly warm. MICROWAVE remaining morsels in small, heavy-duty plastic bag on HIGH (100%) power for 30 to 45 seconds; knead. Microwave at additional 10- to 15-second intervals, kneading until smooth. Cut tiny corner from bag; squeeze to drizzle over cookie. Allow chocolate to cool and set; break cookies into irregular pieces.
