  • 1/2 cup vegetable oil
  • 3/4 cup sugar
  • 2 eggs, beaten
  • 2 bananas, mashed
  • 2 cups flour
  • 1/2 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/4 cup buttermilk
  • 1/2 cup walnuts, chopped
  • 1 teaspoon vanilla
  1. Preheat your oven to 350 degrees F.

  2. In a large mixing bowl, beat sugar and oil.

  3. Add the eggs and bananas and mix well.

  4. Add 1 cup of the flour, along with the baking powder, baking soda, and salt and mix well.

  5. Add 2 tablespoons of the buttermilk and blend.

  6. Add the remaining 1 cup of flour and mix well.

  7. Add the final 2 tablespoons of buttermilk along with the vanilla and blend.

  8. Stir in the chopped walnuts.

  9. Put muffin liners into muffin pan. Spoon batter into the cups, filling about 3/4 to the top. (I like to use a large cookie scoop so I can evenly distribute the batter).

  10. Bake for 25-30 minutes, or until a toothpick placed in the center comes out clean or with just a few crumbs.
