In large bowl, combine first nine ingredients. Stir in peanut butter, honey and melted butter. Press mixture firmly into foil-lined 9x13-inch pan. Bake in preheated 350 F oven for 15 minutes. Remove from oven; sprinkle chocolate chips over bars. Return to oven until chocolate is softened (about 2 minutes). Spread chocolate evenly over bars. Cool slightly. Refrigerate until firm (about 2 hours). Cut into bars; wrap individually. Store in refrigerator.
