1 cup packed light brown sugar (7 oz)
1 cup light corn syrup (8 oz)
1 cup peanut butter (8 oz)
1 cup salted dry-roasted peanuts, chopped (4 oz)
6 cups Rice Crispy cereal ( 6 oz)
1 cup peanut butter chips or semi-sweet chocolate chips
1 cup semisweet chocolate chips, melted in microwave 30-60 seconds
1. Grease 13- by 9-inch baking pan. Bring sugar and corn syrup to simmer in large pot. Off heat, add peanut butter and peanuts, stirring until smooth. Add rice crispy cereal and stir until incorporated.
2. Scrape half the mixture into prepared pan and press into bottom and corners with greased spatula (or with greased gloved hands if making a large volume). Sprinkle peanut butter chips or chocolate chips, if using. Add the remaining mixture, pat the mixture down. Drizzle melted chocolate over top and spread to cover. Let cool completely, about 30 minutes. Slice and serve. (Bars can be stored in airtight container for 2 days.)
