03 - In a large bowl, rub lemon zest into sugar with fingers until fragrant. Add oil, eggs, yogurt, lemon juice, and vanilla extract; whisk until smooth.
04 - Add dry ingredients to wet mixture and stir gently until just combined. Do not overmix.
05 - Toss blueberries with 1 tablespoon flour, then gently fold into batter.
06 - Pour batter into prepared loaf pan and smooth top. Bake for 50-55 minutes or until toothpick inserted in center comes out clean. Tent loosely with foil after 40 minutes if browning too quickly.
07 - Cool loaf in pan for 15 minutes, then lift out and place on wire rack to cool completely.
08 - Whisk powdered sugar and lemon juice until smooth and pourable. Drizzle over cooled loaf. Allow glaze to set before slicing.
