Ingredients
Method
- Mash the bananas in a large bowl. Add the melted butter, sugar, egg, vanilla, and sourdough discard. Whisk until smooth.
- In a separate bowl, whisk the flour, baking soda, and salt.
- Fold the dry ingredients into the wet ingredients with a spatula until just combined. Do not overmix.
- Pour the batter into a greased or parchment-lined 9×5-inch loaf pan. Bake at 350°F (175°C) for 50 to 55 minutes, until a toothpick inserted in the center comes out clean or the bread reads 200°F (93°C) internally.
- Cool in the pan for 15 minutes, then transfer to a wire rack. Slice warm or at room temperature.
Notes
If your bananas are frozen, thaw and drain off any excess liquid before mashing. The bread keeps at room temperature for 3 days, well wrapped, but toasts beautifully after that. The tang deepens overnight, so it is a great make-ahead bake.
