Lots of peanut butter in these brownies makes them extra-rich. This recipe starts with a brownie mix, so it's very simple to make. Peanut butter is added to the mix for even more flavor. The filling is also very easy to make in the microwave oven. Just make sure that you cook the sugar and corn syrup mixture well so the caramel peanut butter filling is smooth and velvety.
And the frosting, made of chocolate chips and peanut butter, is smooth as silk. And it stays soft too, even if the brownies last for a few days. Store them at room temperature covered with foil or the pan lid. Serve them as part of a cookie tray, or alone with a big glass of cold milk. These bars are also wonderful for an after-school treat for the kids.
