Directions:

1. Preheat your oven to 350 degrees F (175 degrees C) and generously grease and flour a 9-inch square baking dish.
2. In a bowl, beat superfine sugar and melted butter with an electric mixer until smooth. Add beaten eggs one at a time, ensuring each is fully incorporated before adding the next.
3. Mix baking soda into sour cream in another bowl, then stir it into the butter mixture until well combined.
4. Stir mashed bananas into the butter mixture, followed by cake flour and baking powder. Mix thoroughly, then stir in the vanilla extract.
5. Pour the banana cake batter into the prepared baking dish.
6. In a separate bowl, mix chopped pecans, brown sugar, and ground cinnamon. Sprinkle this delightful topping over the cake batter.
7. Bake in the preheated oven for approximately 45 minutes or until a toothpick inserted into the center comes out clean.
