01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan and line with parchment paper for easy removal.
02 - In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, and salt until thoroughly blended.
03 - In a large bowl, whisk granulated sugar and eggs until pale and slightly thickened, about 2 minutes. Add vegetable oil, Greek yogurt, lemon juice, lemon zest, and vanilla extract. Mix until smooth and fully incorporated.
04 - Gently fold the dry ingredients into the wet mixture using a spatula. Mix only until just combined to avoid developing gluten, which can result in a tough texture.
05 - Toss fresh blueberries with 1 tablespoon flour in a small bowl. This prevents the berries from sinking to the bottom during baking. Fold the coated blueberries into the batter.
06 - Pour batter into the prepared loaf pan and smooth the top with a spatula. Bake for 50-55 minutes until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
07 - Allow the loaf to cool in the pan for 10 minutes. Carefully remove from the pan and transfer to a wire rack to cool completely before glazing.
08 - In a small bowl, whisk sifted powdered sugar with fresh lemon juice, starting with 1 tablespoon. Add additional juice as needed to reach a thick but pourable consistency.
09 - Drizzle the glaze evenly over the completely cooled loaf. Allow the glaze to set for 15-20 minutes before slicing into 8-10 servings.
