Grease a 9 x 13 inch pan. Mix the cereal and peanuts in a large bowl.
In a medium saucepan stir together the brown sugar and corn syrup over medium heat. Bring the mixture to a boil for 1 minute. Then remove from heat and stir in the peanut butter, vanilla, and salt. Stir until the mixture is smooth.
Pour the peanut butter mixture over the cereal mixture. Toss carefully with a wooden spoon until all of the cereal is covered.
Transfer the mixture into the prepared 9 x 13 inch pan and press down gently. Cool for about 20 minutes.
Melt the chocolate chips in the microwave stirring every 20 seconds until completely melted and smooth. Drizzle over the cooled bars. Let the chocolate cool.
Cut into bars and enjoy!
Notes
If you want you can even put the chocolate in a little ziploc bag to drizzle it. Using a cup place the ziploc bag over the rim of the cup and pour the chocolate into the bag, cut a small hole in a corner, and use that to easily drizzle the chocolate over the bars.
