How to make cereal bars

To make these cereal bars, combine cereal and peanuts in a large bowl. In a medium saucepan set over medium heat, stir together the sugar and corn syrup. Bring the mixture to a boil for one minute. Remove the pan from the heat and stir in the peanut butter, vanilla and salt. Stir until the mixture is smooth.

Pour the sugar mixture over the cereal mixture and toss with a rubber spatula until the cereal is completely coated with the sugar mixture. Line a 13 x 9 inch pan with parchment paper so that the paper hangs over the sides. Butter or grease the parchment paper. Pour the mixture into the prepared pan. Spread evenly over the bottom of the pan. Be careful not to crush the cereal.

Place the pan in the refrigerator for 20 minutes to chill.

While the mixture is chilling, melt chocolate in a heatproof bowl set over a pot of simmering water. Use a spoon or piping bag to drizzle the chocolate over the bars. Allow the chocolate to set before cutting into small bars.
