Ingredients
  

Dry ingredients
  • 1.5 cup all-purpose flour
  • 1 tsp baking soda
  • 0.5 tsp baking powder
  • 0.5 tsp salt
  • 1 tsp cinnamon
Sweet base
  • 0.5 cup granulated sugar
  • 0.25 cup brown sugar
  • 2 eggs
  • 0.33 cup vegetable oil
  • 1 tsp vanilla extract
  • 3 very ripe bananas, mashed about 1 cup
Vegetable add-in
  • 1 cup zucchini, grated and squeezed dry
Optional mix-ins
  • 0.5 cup walnuts or chocolate chips optional

Equipment

  • 1 sheet pan

Method
 

Prep and heat
  1. Preheat the oven to 350°F and grease a 9x5 loaf pan.
Mix dry and wet
  1. Whisk all-purpose flour, baking soda, baking powder, salt, and cinnamon together until evenly combined.
  2. Mash very ripe bananas in a large bowl, then stir in granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until smooth and combined.
  3. Stir in grated zucchini that has been squeezed dry so the batter won’t be watery.
Combine and bake
  1. Fold the dry ingredients into the wet ingredients just until no streaks of flour remain, then fold in walnuts or chocolate chips if using.
  2. Pour the batter into the greased loaf pan, then bake at 350°F for 55–65 minutes until deep golden and a toothpick in the center comes out clean (visual cue: golden top and set center).
Cool and slice
  1. Cool in the pan for 15 minutes before slicing so the crumb firms up.

Notes

Pro tip: squeeze the grated zucchini very dry for a tender, not-gummy crumb. Store tightly covered in the fridge for up to 4 days (bring slices to room temp for best texture); freeze up to 2 months. For a dairy-free option, use dairy-free chocolate chips if substituting for walnuts.
