Got ripe bananas and a bit of sourdough starter hanging out in your fridge? This is the recipe for you. Sourdough banana bread is everything banana bread should be—soft, rich, and just sweet enough!
1. Prep the Oven & Pan
Preheat your oven to 360°F. Then, grease a loaf pan with butter and set aside.
2. Mix Wet Ingredients
In a large bowl, mash the bananas. Stir in the brown sugar and vanilla. Add eggs one at a time, mixing well after each. Then, stir in your sourdough starter until smooth.
3. Mix Dry Ingredients
In a separate bowl, sift together the flour, baking soda, and salt.
4. Combine Everything
Gradually add the dry mixture to the banana mix, stirring gently between batches. Next, pour in the milk and oil, and mix until just combined—be careful not to overdo it.
5. Bake
Pour the batter into your prepared loaf pan. Bake for about 1 hour, or until golden brown and a toothpick comes out clean.
6. Cool & Serve
Let the loaf cool in the pan for 10–15 minutes, then transfer to a rack. Dust with powdered sugar and serve with butter or mascarpone, if you like.
