Ingredients
Method
- Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan or two 9-inch round cake pans.
- In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
- Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract and mashed bananas until well combined.
- In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. Gradually add these dry ingredients to the banana mixture, alternating with the sour cream.
- Gently fold in the chopped walnuts.
- Pour the batter into your prepared pan(s) and spread evenly. Bake for 35-40 minutes for a 9x13 pan, or 25-30 minutes for round pans.
- Let the cake cool in the pan for 15 minutes before transferring to a wire rack.
Notes
Use room temperature ingredients for better incorporation. Mash bananas thoroughly for the right consistency. Toast walnuts for enhanced flavor. Avoid opening the oven door during the first 25 minutes of baking.
