Chocolate-Bottom Banana Square

By now, you may have seen many bloggers baked this delicious cake. Yes I'm joining the craze too. This is a simple and delicious recipe and I had made twice already. Everyone who I shared this cake with gave a thumb up! Definitely a keeper! Thanks Hearty Bakes for sharing this wonderful recipe. I twisted a bit by adding walnut and the next time I will omit the chocolate to turn it to a Banana Walnut Square. I think it will be very nice too as the cake was soft and moist.
