Preheat the oven to 350ºF. Grease a 9x5-inch loaf pan with nonstick cooking spray and set it aside.
In a large bowl,whisk together the all-purpose flour, baking powder, and salt. Set the dryingredients aside.
In a separate bowl,combine the oil, granulated sugar, sour cream, eggs, fresh lemon juice, lemonzest, and vanilla extract. Mix until the ingredients are fully combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
In a separate bowl,gently toss the blueberries with 2 teaspoons of flour to coat them. Fold theflour-coated blueberries into the batter.
Pour the batter intothe prepared loaf pan and spread it evenly.
Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean. If the top is browning too quickly, cover it loosely with foil for the last 10-15 minutes of baking.
Remove the pan fromthe oven and let the bread cool for about 20 minutes. Carefully remove thebread from the pan and transfer it to a wire rack to cool completely.
Once the bread hascooled, prepare the zesty lemon glaze. In a bowl, whisk together theconfectioners' sugar and fresh lemon juice until smooth. Adjust the lemon juicequantity to achieve the desired consistency.
Using a spoon, drizzle the glaze over the cooled bread, allowing it to spread and set for about 15-20 minutes.
