Chocolate-Bottom Banana Squares

Saw it on Cook.Bake.Love's website then 鲸鱼's website. If you love the combination of chocolate and bananas, this recipe is a sure keeper. Thanks Angel for sharing this beautiful recipe. When I grabbed one piece of the cake, the chocolate chips on top melted and sticked on my fingers ... it was fingers licking good :D My cake sat in the oven for 45 mins. the surface still doesn't browning, then I gave up, that's with a yellowish surface.
