There’s something special about the way Aunt Becky’s kitchen smelled when this bread came out of the oven — sweet bananas, toasted nuts, and those little bursts of blueberry that make every slice feel like home. This loaf bakes up incredibly moist with a tender crumb, the kind of simple comfort you can enjoy warm…
Aunt Becky’s Blueberry Banana Bread
A moist banana bread made with mashed bananas, fresh blueberries, and a touch of sour cream for added tenderness.
Ingredients
- 1/2 cup butter (melted)
- 1 cup white sugar
- 2 eggs
- 1 tsp vanilla extract
- 1 tsp lemon juice
- 1 3/4 cups all-purpose flour (Reserve 2 tbsp for coating the berries)
- 1 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp salt
- 1/2 cup sour cream
- 2 medium bananas (mashed)
- 1 1/2 cups fresh blueberries
Instructions
Oven & Pan Prep
- Preheat your oven to 350°F (175°C). Thoroughly grease a standard 9×5 inch loaf pan, or line it with parchment paper for effortless removal.
Combine Wet Ingredients
- In a large bowl, mix together the melted butter and white sugar. Add the eggs, vanilla extract, and lemon juice. Whisk until fully combined and smooth.
The Flour Separation (Critical Step)
- Measure out your 1 3/4 cups of flour. Remove 2 tablespoons of the flour and place it into a small bowl with the blueberries. Toss gently until the berries are completely coated. This layer prevents them from sinking to the bottom of the pan.
Sift & Incorporate Dry Base
- In a separate bowl, whisk together the remaining flour, baking soda, baking powder, and salt. Pour the dry ingredients into the wet butter mixture and mix gently until just combined.
Fold the Heavy Elements
- Mash your bananas with a fork. Gently fold the mashed bananas, sour cream, and the flour-coated blueberries into the batter until evenly distributed. Do not over-mix.
Bake to Perfection
- Spread the batter evenly into your prepared 9×5 inch loaf pan. Bake at 350°F for 60 to 70 minutes. Because of the extra moisture from the blueberries, it may take 5 to 10 minutes longer than a standard loaf. Test with a toothpick in the absolute center.
Cool Thoroughly
- Remove from the oven and let the bread cool inside the pan for 10 minutes. Then, turn it out onto a wire rack to cool completely before slicing.
BAKING BEST PRACTICE: Keep an eye on the loaf around the
- 45-minute mark. If the top crust is beautifully golden brown but the center isn’t fully cooked yet, loosely tent a sheet of aluminum foil over the top of the pan to prevent over-browning while it finishes baking.

Notes
- Coating the blueberries in 2 tablespoons of the flour is essential — it keeps them from sinking to the bottom of the loaf.
- Blueberries add extra moisture, so the loaf may need the full 70 minutes to bake.
- Tent with foil if the top browns too quickly around the 45‑minute mark.
- Use fresh blueberries when possible; frozen berries can make the loaf wetter and may require extra bake time.
- Let the loaf cool completely before slicing so it sets properly.
- I know waiting to cut into your bread is tough, but letting it sit until the next day and heating it slightly will really bring out the flavor.
