Heat oven to 350 degrees. Line a 13x 9 pan with foil, leaving a 1 inch overhang; set aside. Combine brown sugar, butter, and peanut butter in a large bowl. Beat at medium speed, scraping bowl often, until creamy. Add eggs and vanilla; continue beating until well mixed. Stir in chocolate chips. Pat dough into prepared pan. Sprinkle with sugar. Bake for 20-22 minutes or until golden brown. Immediately press evenly spaced chocolate candies into warm bars. Cool completely. Remove bars from pan using edges of foil; cut into bars, cutting between candies.
