Brownie Caramel Pecan Bars

Heat oven to 350°F (175°C). Line 9-inch square baking pan with foil, extending foil over edges of pan; grease and flour foil. Combine sugar, butter and water in medium saucepan; cook over low heat, stirring constantly, until mixture boils. Remove from heat; immediately add 1 cup chocolate chips, stirring until melted. Beat in eggs and vanilla until well blended. Stir together flour, baking soda and salt; stir into chocolate mixture. Spread batter into prepared pan. Bake 15 to 20 minutes or until brownies begin to pull away from sides of pan. While brownies are baking, prepare CARAMEL TOPPING. Remove brownies from oven; immediately and carefully spread with caramel topping. Sprinkle remaining 1 cup chips and pecans over topping; lightly press into topping. Cool completely in pan on wire rack, being careful not to disturb chips while soft. Lift out of pan; cut into bars.
