1. Bake the brownies according to the box directions in a 9×9 pan. Line with foil, parchment paper or spray with non- stick spray.

2. Take the brownies out with 5 minutes left of baking, sprinkle the chopped peanut butter cups and peanuts over the top of the warm brownies. Return to the oven for 5 more minutes.

3. Once you pull the brownies out of the oven, spread the peanut butter cups/peanut mixture with a knife or off-set spatula so you have a nice smooth layer. Let brownies cool.

4. Combine the chocolate chips, peanut butter and butter in a microwave safe bowl. Microwave for 1 minute then stir. Then microwave for 20 second increments, stirring after each until the mixture is melted and smooth.

5. Stir the cereal, vanilla and salt into the melted chocolate mixture until all combined.

6. Pour the chocolate mixture over the brownies and smooth with a spatula. Chill in the fridge for about 2 hours. Then remove and cut into bars. I found that if I kept these at room temperature for too long, they became messy and the layers fell apart. I recommend storing in the fridge.
