Method
Prep the oven and pan
- Preheat the oven to 350°F, and set an oven rack to the middle position. Grease a 9×5 loaf pan thoroughly so the loaf releases cleanly.
Mix the banana batter
- Mash the bananas thoroughly in a large bowl until almost smooth. Leave only a few tiny lumps for best texture.
- Stir in the melted butter, granulated sugar, egg, and vanilla until glossy and evenly combined. Mix just until no dry pockets remain.
- Add the baking soda and salt, then stir briefly to distribute. The batter may look slightly thicker as the baking soda activates.
- Fold in the all-purpose flour until just combined, stopping as soon as you don’t see streaks. Do not overmix to keep the crumb tender.
Add swirl (optional)
- Pour the batter into the prepared loaf pan and smooth the top. Tap the pan once to help the batter settle.
- For swirl, drop spoonfuls of peanut butter or Nutella on top, then add brown sugar and cinnamon if using. Drag a skewer through the surface to create swirls.
Bake and cool
- Bake for 60–65 minutes at 350°F, until a toothpick inserted in the center comes out clean. If the top browns too quickly, loosely tent with foil for the last 10 minutes.
- Cool the loaf in the pan for 15 minutes before slicing. This helps the center set so slices hold their shape.
Notes
For the sweetest flavor and best natural moisture, use bananas that are heavily freckled to nearly black. Storage: keep tightly wrapped at room temperature for 2 days or refrigerate up to 5 days. Freezer: yes—wrap slices individually and freeze up to 2 months. Dietary swap: substitute 1:1 gluten-free all-purpose flour for the regular flour to make it gluten-free (check label for xanthan/guar).
