Ingredients
Method
- Preheat oven to 350°F (175°C) with a rack in the middle. Grease a 9x5-inch loaf pan and line with parchment.
- Mash banana in a large bowl. Whisk in melted butter, sugar, eggs, sour cream, and vanilla until glossy.
- Sift flour, baking soda, and salt over the wet mixture. Fold with a spatula just until no dry spots remain.
- Gently fold in the blueberries until evenly distributed, about 8–10 strokes.
- Scrape batter into the loaf pan and bake 55–60 minutes until a toothpick inserted in the center comes out with just a few moist crumbs.
- Cool in the pan 10 minutes, then lift out and cool completely on a rack before slicing.
Notes
The loaf needs to cool fully before you get clean slices. If you can’t wait, a serrated knife and a gentle sawing motion help, but expect slightly crumbly pieces when it’s still warm.
