This ultra-moist blueberry banana bread is packed with ripe bananas and juicy blueberries for a soft, tender crumb and bursts of fruit in every bite. It’s a simple one-bowl batter with pantry staples—perfect for breakfast, snacks, or dessert.
Preheat oven to 350°F. Grease a 9×5-inch loaf pan and line with a parchment sling for easy removal.
In a large bowl, whisk flour, baking soda, baking powder, salt, and cinnamon until evenly combined.
In a separate bowl, whisk mashed bananas, granulated sugar, brown sugar, melted butter, eggs, vanilla, and yogurt until smooth.
Add the dry ingredients to the wet and fold gently just until no dry streaks remain. Do not overmix.
Toss blueberries with 1 teaspoon flour (taken from the measured flour) to help prevent sinking, then fold them and the lemon zest into the batter.
Scrape batter into the prepared pan and smooth the top. Sprinkle with coarse sugar if using.
Bake 55–65 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Tent loosely with foil if browning too quickly.
Cool in pan for 15 minutes, then lift out to a wire rack to cool completely before slicing.
Notes
For extra blueberry pops, reserve 0.25 cups berries and press them on top before baking. Bread keeps 3 days covered at room temperature or up to 3 months frozen.
