Ingredients

2/3 cup packed brown sugar
4 1/2 tablespoons unsalted butter, cut into small pieces
3 medium bananas, sliced 1/4-inch thick
1 3/4 cups all-purpose flour
1 1/2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon ground cinnamon
1 pinch salt
3/4 cup white sugar
1/3 cup unsalted butter, softened
2 large eggs
1 1/2 teaspoons vanilla extract
2 medium overripe bananas, mashed
1/3 cup sour cream

Directions

1 Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C). Grease an 8-inch square cake pan.
2 Spread brown sugar on the bottom of the prepared pan and scatter butter pieces on top.
3 Place the pan in the preheated oven until butter has melted, 5 to 7 minutes. Remove from the oven; stir and spread mixture evenly on the bottom of the pan. Arrange sliced bananas to cover the bottom. Set aside.
4 Stir flour, baking powder, baking soda, cinnamon, and salt together in a large bowl; set aside.
5 Beat white sugar and butter together with an electric mixer in a large bowl. Mix in eggs and vanilla until well combined. Add mashed bananas and sour cream; mix to combine. Add flour mixture on low speed and beat until batter is just combined.
6 Pour batter over banana slices in the pan and smooth the top.
7 Bake in the preheated oven until a toothpick inserted into the center comes out completely clean, 30 to 35 minutes.
8 Let cool in the pan for about 30 minutes before inverting and slicing.
