Method
Prep
- Preheat oven to 350°F and grease a 9x5 loaf pan.
- Whisk together all-purpose flour, baking soda, baking powder, salt, and cinnamon until evenly combined.
Make the batter
- Mash the very ripe bananas in a large bowl.
- Add granulated sugar, brown sugar, eggs, vegetable oil, Greek yogurt, and vanilla extract, then stir to combine.
- Stir in grated zucchini that has been squeezed dry.
- Fold the dry ingredients into the wet ingredients just until combined.
- Gently fold in the 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, ensuring the full bake time for a moist banana-blueberry crumb.
- Cool for 15 minutes before slicing.
Notes
Pro tip: Grate the zucchini and squeeze it dry very well—excess moisture can make the loaf gummy even when it’s baked through. Store in an airtight container in the fridge for up to 4 days; freeze sliced portions up to 3 months. For a lighter option, replace the vegetable oil with an equal amount of unsweetened applesauce and expect slightly softer crumb.
