01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan and line with parchment paper, allowing overhang on sides for easy removal.
02 - In a medium bowl, whisk together 1 1/2 cups flour, baking powder, baking soda, and salt until well combined.
03 - In a large bowl, whisk granulated sugar and eggs until pale and slightly thickened, about 1 minute. Add oil, 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 just until combined—do not overmix or the cake will become dense.
05 - Place blueberries in a small bowl and toss with 1 tablespoon flour until lightly coated. This prevents them from sinking to the bottom during baking.
06 - Gently fold the flour-coated blueberries into the batter, taking care not to crush them.
07 - Pour batter into the prepared loaf pan and smooth the top with a spatula. Bake for 50-55 minutes, or until a wooden toothpick inserted into the center comes out clean or with a few moist crumbs.
08 - Let the cake cool in the pan for 10 minutes. Using the parchment paper overhang, lift the cake from the pan and transfer to a wire rack. Cool completely before glazing, about 1 hour.
09 - In a small bowl, whisk together powdered sugar and 1 tablespoon lemon juice. Add additional lemon juice, 1 teaspoon at a time, until the glaze reaches a thick but pourable consistency.
10 - Drizzle the glaze evenly over the completely cooled cake, allowing it to drip down the sides. Let the glaze set for 15-20 minutes before slicing.
