We've added so much chocolate to a devil's food cake mix that no one will ever guess it came from a box. Chopped peanut butter cups are stirred into the batter and the frosting is a luscious blend of dark chocolate, heavy cream, and peanut butter.
These are the most decadent brownies ever! Start with your favorite boxed brownie mix and top with a peanut butter cheesecake layer and Reese's Peanut Butter Cups. The perfect dessert for a party or just because! If you love the combination of chocolate and peanut butter, you've got to try these brownie bars.
