Ingredients

  • 1 ½ cups all-purpose flour
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp salt
  • 1 cup granulated sugar
  • 2 large eggs
  • ½ cup plain Greek yogurt
  • cup vegetable oil
  • 2 tbsp fresh lemon juice
  • 1 tbsp lemon zest
  • 1 tsp vanilla extract
  • 1 cup fresh or frozen blueberries tossed in 1 tsp flour

For the Glaze (optional)

  • ½ cup powdered sugar
  • 1 –2 tbsp fresh lemon juice

Instructions

  • Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×5 inch loaf pan and line with parchment paper.
  • Mix Dry Ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  • Combine Wet Ingredients: In a large mixing bowl, whisk sugar and eggs until light and fluffy. Add yogurt, oil, lemon juice, lemon zest, and vanilla extract. Mix well.
  • Add Dry to Wet: Slowly stir in the dry ingredients until just combined—don’t overmix.
  • Fold in Blueberries: Gently fold in the blueberries tossed in flour. This helps prevent them from sinking to the bottom.
  • Pour and Bake: Pour batter into the prepared loaf pan. Smooth the top and bake for 45–55 minutes, or until a toothpick comes out clean from the center.
  • Cool Down: Let the loaf cool in the pan for 10 minutes before transferring it to a wire rack.
  • Add Glaze (Optional): Mix powdered sugar with lemon juice and drizzle over the cooled loaf. Let the glaze set before slicing.

Notes

  • Use Room Temperature Ingredients – They blend more easily and create a smoother batter.
  • Don’t Overmix – Stir just until the flour disappears to keep the loaf soft and fluffy.
  • Coat Blueberries with Flour – This prevents them from sinking during baking.
  • Let It Cool Fully Before Glazing – A hot loaf will melt the glaze and make it runny instead of pretty.
