Ingredients

  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 3 large eggs
  • 1 cup granulated sugar
  • 1/2 cup sour cream
  • 1/2 cup vegetable oil
  • 1 tbsp lemon zest
  • 1/4 cup fresh lemon juice
  • 1 tsp vanilla extract
  • 1 cup powdered sugar (for the glaze)
  • 12 tbsp lemon juice (for the glaze)
  • 1 tbsp milk or cream (for the glaze)

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
  3. In a large bowl, beat eggs and sugar until light and fluffy. Add sour cream, oil, lemon zest, lemon juice, and vanilla extract; mix well.
  4. Gradually stir the dry ingredients into the wet until just combined.
  5. Pour batter into the prepared pan and bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
  6. Let the loaf cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely.
  7. For the glaze, whisk powdered sugar with lemon juice and milk until smooth.
  8. Drizzle the glaze over the cooled loaf and let it set before slicing and serving.

Notes

  • Substitute Greek yogurt for sour cream for a tangy, protein-rich twist.
  • Add lemon extract for a stronger lemon flavor.
  • Mix in poppy seeds for variation.
  • Store at room temperature for 3 days, or refrigerate for up to a week.
  • Freeze slices individually for longer storage.
