Method
Prep and preheat
- Preheat oven to 350°F, then grease a 9x5 loaf pan.
- Whisk all-purpose flour, baking soda, baking powder, salt, and cinnamon together in a bowl.
Make the batter
- Mash very ripe bananas in a large bowl, then add granulated sugar, brown sugar, eggs, vegetable oil, Greek yogurt, and vanilla extract and stir to combine.
- Stir in grated and squeezed dry zucchini.
- Fold the dry ingredients into the wet mixture until just combined, then gently fold in blueberries that have been tossed in flour.
Bake and cool
- Pour the batter into the prepared loaf pan.
- Bake for 60–70 minutes at 350°F until a toothpick in the center comes out clean, letting the full bake time set the moisture from the bananas and blueberries.
- Cool for 15 minutes before slicing.
Notes
Pro tip: squeeze the grated zucchini dry so the loaf bakes with a tender, not gummy, crumb. Store tightly wrapped at room temperature for up to 3 days or in the fridge for up to 5 days; freeze sliced portions for up to 2 months. For a dairy swap, use plain lactose-free yogurt 1:1 instead of Greek yogurt if needed.
