Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 1/2 cups mashed ripe bananas (about 4 medium)
- 1 teaspoon vanilla extract
- 1/2 cup sour cream
- 1/2 cup chopped walnuts (optional)
Instructions
- Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
- In a bowl, whisk together flour, baking soda, and salt.
- In a large bowl, cream butter and sugar until light and fluffy. Add eggs one at a time, mixing well after each.
- Stir in mashed bananas and vanilla extract.
- Add dry ingredients alternately with sour cream, mixing just until combined. Fold in walnuts, if using.
- Pour batter into prepared pan and smooth the top. Bake for 25–30 minutes or until a toothpick comes out clean.
- Cool in the pan on a wire rack before slicing and serving.
Notes
- Replace walnuts with chocolate chips for a sweeter version.

- Swap half the butter with oil for a lighter texture.
- Use thawed frozen bananas with excess liquid drained.
