Thanks, Cyd! I ended up making these bars this weekend to help celebrate our anniversary, and they turned out so delicious! The chocolate frosting is super rich, but the peanut butter cake bars aren't, so they even each other out! We love peanut butter and chocolate around here, so I'll make these again.

This is so easy but I wished I would have added mini chocolate chips to the batter. I also had to add so much more powdered sugar to the frosting. I would cut back on milk next time. My peanut butter fans are in love with this.

Do you put the frosting on the cake warm or cooled? Like Texas sheet cake frosting goes on warm cake. Thanks!
