Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and lightly grease a 9x5-inch loaf pan.

- In a large mixing bowl, whisk together the egg, light brown sugar, granulated sugar, oil, sour cream, and vanilla extract until smooth.

- Gently mix in the all-purpose flour, baking powder, baking soda, and salt until just combined.

- Fold in the mashed bananas and grated zucchini until thoroughly integrated.

- Toss the blueberries in a bit of flour and fold them into the batter carefully to avoid breaking them.

- Pour the batter into the prepared loaf pan and smooth the top with a spatula.

- Bake for 75-90 minutes, checking for doneness with a toothpick in the center.

- Allow the bread to cool in the pan for 15 minutes before transferring it to a wire rack to cool completely.
