  • 1 cup granulated sugar divided
  • ½ cup vegetable oil
  • 1/4 teaspoon salt
  • 1 medium overripe banana
  • 2 large eggs
  • 5 ounces buttemilk/sour milk (7 tablespoons)
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • 2 teaspoons cinnamon divided
  • 2 cups all purpose flour
  • 1 cup shredded zucchini about 1 medium


  • Preheat oven to 350°F. Grease a 9x5x3” loaf pan with nonstick cooking spray.
  • Stir oil and 3/4 cup sugar with a wooden spoon. Add bananas, eggs, milk, vanilla, 1 teaspoon cinnamon, salt and baking soda and mix until almost smooth (there will be some lumps from the banana).
  • Mix in flour until just incorporated, then stir in zucchini. Pour into prepared pan.
  • Combine 1/4 cup sugar and 1 teaspoon cinnamon in a small bowl. Sprinkle evenly over the top of the batter.
  • Bake for 40-50 minutes3 until a toothpick comes out with just a few crumbs. The edges will be a dark brown and there will be a nice crack down the center.
  • Cool completely before removing loaf from pan, but you can cut slices from the pan after it’s cooled for about 15-20 minutes.



  • In place of vegetable oil you can also use 1/2 cup softened unsalted butter.
  • In place of sour milk you can use buttermilk. Make your own buttermilk if you don't have it.
  • You can use dairy-free milk (i.e. almond milk) but then add 1 tsp vinegar or lemon juice to the batter.
