01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan and line with parchment paper for easy removal.
02 - Whisk together 1 1/2 cups flour, baking powder, and salt in a medium bowl until thoroughly blended.
03 - In a large bowl, whisk granulated sugar, eggs, Greek yogurt, vegetable oil, lemon zest, lemon juice, and vanilla extract until completely smooth and incorporated.
04 - Gradually fold the dry ingredients into the wet mixture using a spatula, mixing just until combined. Avoid overmixing to prevent tough texture.
05 - Toss fresh blueberries with 1 tablespoon flour in a small bowl to coat, then gently fold into the batter until evenly distributed.
06 - Pour batter into the prepared loaf pan and smooth the top surface. Bake for 50-55 minutes until a toothpick inserted into the center comes out clean.
07 - Allow the loaf to cool in the pan for 15 minutes before removing. Transfer to a wire rack to cool completely before glazing.
08 - Whisk powdered sugar with 2-3 tablespoons fresh lemon juice until smooth and pourable. Adjust consistency with additional juice if needed.
09 - Drizzle the lemon glaze evenly over the completely cooled loaf. Allow glaze to set for 10-15 minutes before slicing into 8 servings.
