01 - Preheat oven to 350°F. Grease and line a 9x5-inch loaf pan with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well combined.
03 - In a large bowl, whisk sugar and eggs until pale and slightly thickened. Add oil, yogurt, lemon juice, lemon zest, and vanilla; mix until smooth.
04 - Gently fold dry ingredients into wet mixture until just combined. Do not overmix.
05 - Toss blueberries with 1 tablespoon flour, then fold into batter.
06 - Pour batter into prepared loaf pan and smooth the top. Bake for 50-55 minutes, or until a toothpick inserted into the center comes out clean.
07 - Cool in pan for 10 minutes, then transfer to a wire rack to cool completely.
08 - In a small bowl, whisk powdered sugar with enough lemon juice to reach a pourable consistency. Drizzle glaze over cooled loaf and allow to set before slicing.
