Preheat the oven to 175°C (350°F). Grease or line an 8x4-inch loaf pan with parchment paper.
In a large mixing bowl, mash the bananas with a fork until smooth.
350 g very ripe bananas
Stir in the melted butter until well combined.
76 g unsalted
Add the baking soda and a pinch of salt, mixing gently.
½ teaspoon baking soda, 1 pinch Salt
Stir in the sugar, beaten egg, and vanilla extract until smooth.
150 g granulated sugar, 1 Large egg, 1 teaspoon vanilla extract
Fold the flour into the mixture until just combined - avoid overmixing, or the bread may turn dense.
205 g All-purpose flour
Gently stir in the blueberries, keeping a few aside to sprinkle on top if you like.
150 g blueberries
Pour the batter into the prepared loaf pan and smooth the surface.
Bake for 55–60 minutes. Test with a toothpick or skewer, it should come out clean or with just a few dry crumbs. If the top browns too quickly, cover loosely with foil and continue baking until the center is set.
Allow the loaf to cool in the pan for 5-10 minutes, then transfer to a wire rack to cool completely before slicing.
Notes
Tips and Tricks
If using frozen blueberries, don’t thaw them before adding to the batter, this helps prevent streaky purple bread.
Toss the blueberries in a teaspoon of flour before folding them in. This helps stop them from sinking to the bottom.
Use extra-ripe bananas for the best natural sweetness and moist texture.
Store at room temperature for 2-3 days or refrigerate for up to a week. Freeze slices individually for up to 2 months.
For a sweeter loaf, add a sprinkle of coarse sugar or a few extra blueberries on top before baking.
