- 1 1/3 cups vegetable oil
- 2 cups white sugar
- 4 eggs, whisked
- 5 cups mashed bananas
- 1 tablespoon lemon juice
- 4 cups all-purpose flour
- 2 tablespoons baking powder
- 1 teaspoon salt
- 2 cups chopped walnuts
- Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9×5-inch loaf pans.
- Beat vegetable oil and sugar together in a bowl until creamy and smooth; stir in eggs.
- Mash bananas and lemon juice together in a separate bowl; mix into oil mixture until just incorporated.
- Sift flour, baking powder, and salt together in a third bowl; slowly mix into wet mixture using an electric mixer on low until just incorporated. Fold in walnuts. Pour batter into the two prepared loaf pans.
- Bake in the preheated oven until a knife inserted in the center of the loaf comes out clean, about 1 hour 15 minutes.
