I love sheet cake! My mom has made the most amazing chocolate Texas sheet cake since I was a little girl licking the batter bowl (hmmm, I guess I still do that). Recently I heard about a peanut butter version of this childhood favorite. At first I thought, “sounds great!” Then I had an idea I just knew would taste great. Chocolate sheet cake with peanut butter icing! Chocolate peanut butter is one of my favorite flavor combinations so I decided to try it.
