Chocolate PB Banana Upside Down Cake

Steps

1. Preheat the oven to 350 degrees and lightly grease or butter the sides of a 9×13 glass baking dish. In a medium bowl, whisk the flour with the baking powder, salt, and cocoa.

2. In a standing electric mixer, beat 2 sticks of butter with the granulated sugar at medium speed until very fluffy, about 5 minutes. Beat in the eggs one at a time. Add the vanilla. Beat in the flour mixture and the milk.

3. In a small bowl, blend the remaining stick of butter with the brown sugar and spread it in the baking dish. Arrange the bananas, cut sides down, in the dish. Spoon dollops of the peanut butter into the dish and fill in the gaps with the chocolate batter. Bake for 45 minutes. Let the cake cool for 10 minutes, then loosen the edges with a knife and invert in onto a platter. Let the cake cool slightly, then cut into squares and serve.
