Directions

  1. Prep pans
    Preheat oven to 360°F. Lightly butter one 9×5-inch pan or three 7x3x2-inch mini loaf pans.

  2. Mix bananas & sugar
    In a bowl, cream bananas, sugar, and vanilla with mixer for 30–60 seconds (small banana lumps are fine).

  3. Add eggs & starter
    Add eggs one at a time, mixing until combined. Stir in sourdough starter.

  4. Add dry ingredients
    Sift flour, baking soda, and salt. Add to banana mixture in batches.

  5. Add liquids
    Pour in oil and milk, mixing until just combined. (Do not overmix — prevents toughness.)

  6. Bake
    Transfer batter to prepared pan(s).

    • Mini loaves: Bake 45 minutes.

    • Standard loaf: Bake 60–65 minutes.
      Check doneness with a toothpick. Cover with foil if browning too quickly.

  7. Cool
    Let cool in pan 20 minutes. Transfer to wire rack to cool fully.

  8. Serve
    Dust with powdered sugar or spread with butter/mascarpone if desired.

⚠️ Baking times may vary depending on oven type, pan size, and elevation. Always test with a toothpick before removing from oven.
