Bake an additional 20 to 25 minutes or until top is deep golden brown and center is set. Cool 5 minutes.
In small saucepan, combine chocolate chips and oil. Cook over medium heat until chips are melted, stirring constantly. Carefully pour over filling; gently spread to cover. Sprinkle with pecans. Refrigerate 1 1/2 hours or until chocolate is set. Cut into bars. Store in refrigerator.
