Preheat your oven to 350°F (175°C) and grease and flour a 9x13-inch baking dish or line it with parchment paper.
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set aside.
In a large bowl, use a hand mixer or stand mixer to cream the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
Beat in the eggs, one at a time, followed by the vanilla extract. Mix until well combined.
Add the mashed bananas and sour cream to the wet ingredients and mix until fully incorporated.
Gradually add the dry ingredients into the wet ingredients, mixing on low speed just until combined. Do not overmix.
To make the streusel, mix the brown sugar, flour, ground cinnamon, and melted butter in a small bowl until crumbly. Stir in the chopped walnuts if using.
Pour half of the banana batter into the prepared baking dish and spread it evenly.
Sprinkle the streusel mixture evenly over the batter layer.
Pour the remaining batter over the streusel layer and spread it evenly to cover.
Bake the cake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Slice and serve the banana cake as is, or with a dollop of whipped cream or a dusting of powdered sugar, if desired.
