Instructions

  • Preheat the oven to 350°F and grease a loaf pan.
  • Mix flour, salt, baking powder, and baking soda in a medium bowl. Set aside.
  • In a large bowl, stir together melted butter and cane sugar until smooth and creamy.
  • Add eggs one at a time, beating well after each addition.
  • Stir in sourdough discard, lemon juice, vanilla, lemon zest, and lemon oil until fully combined.
  • Fold in the dry ingredients gently, mixing just until no dry flour remains.
  • Pour the batter into the prepared loaf pan and smooth the top evenly.
  • Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean.
  • Let cool in the pan for 10-20 minutes, then transfer to a wire rack to cool completely.
  • Mix powdered sugar and lemon juice for glaze, then drizzle over cooled bread before serving.

Notes

Don’t skip the lemon zest—it carries most of the lemon flavor. For a dairy-free version, substitute butter with a neutral oil like avocado. Older discard gives a stronger tang. Long ferment overnight if desired. Add nuts or fruit after mixing for variety.
