Peanut Butter Brownies are awesome. These luscious brownies start with a fudge brownie mix, but peanut butter chips added to the batter amp up the flavors exponentially! The cream cheese, peanut butter frosting is to die for. These drool-worthy brownies are the perfect dessert for company dinners, potlucks, tailgating parties or holiday baking. If you enjoy peanut butter and chocolate dessert combinations, this is one of the best!
