- 3 bananas, mashed
- 1 cup white sugar
- 2 eggs, lightly beaten
- 3/4 cup vegetable oil
- 2 cups all-purpose flour
- 2 teaspoons baking soda
- 3 tablespoons buttermilk
- 1 cup chopped pecans (optional)
- 1 cup confectioners' sugar, or as needed
- Preheat oven to 300 degrees F (150 degrees C). Grease 14 muffin cups.
- Lightly beat bananas and white sugar together in a bowl until smooth; add eggs, one at a time, until incorporated. Beat in vegetable oil until well blended, 1 to 2 minutes. Stir in flour, baking soda, and buttermilk; mix well. Fold in pecans. Pour batter into the prepared muffin cups.
