Preheat your oven to 350F (175C). Lightly grease an 8X4 inch or 9X5 inch loaf pan and set it aside.
In a medium mixing bowl, combine the flour, baking powder, and salt. Whisk together until evenly mixed.
In a large bowl, add the sugar and lemon zest. Rub the zest into the sugar using your fingers until fragrant. This helps release the lemon oils and enhances the flavor. Add yogurt, olive oil, eggs, and vanilla extract, the whisk everything together until smooth.
Gradually add the dry ingredients into the wet mixture, stirring just until incorporated. Gently fold in the blueberries. The batter will be fairly thick.
Transfer the batter to the prepared loaf pan and spread the top evenly with a spatula. Bake for 40-50 minutes, or until a toothpick inserted in the center comes out clean.
Allow the loaf to cool completely in the pan before removing it. Finish by drizzling lemon glaze over the top before slicing and serving. By using icing sugar and lemon juice.
