Ingredients
1 cup white sugar
½ cup butter, melted
2 eggs
1 teaspoon vanilla extract
1 ½ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon salt
½ cup sour cream
½ cup chopped walnuts
2 medium bananas, sliced
Directions
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9×5-inch loaf pan.
Stir sugar and melted butter together in a large bowl. Add eggs and vanilla; mix well. Combine flour, baking soda, and salt; stir into butter mixture until smooth. Fold in banana slices, sour cream, and walnuts; transfer into the prepared pan.
Bake in the preheated oven until a toothpick inserted into the center of the loaf comes out clean, about 1 hour. Cool loaf in the pan for 10 minutes before inverting onto a wire rack to cool completely.
