Preheat and Prep : Preheat your oven to 350°F (175°C). Grease a standard loaf pan and line it with parchment paper for easy removal. Toss the blueberries in a tablespoon of flour to prevent them from sinking during baking.

Mix Wet Ingredients : In a large mixing bowl, whisk together the Greek yogurt, vegetable oil, eggs, lemon zest, and vanilla extract until smooth and well combined.

Combine Dry Ingredients : In a separate bowl, sift together the flour, baking powder, sugar, and salt. Gradually add the dry mixture to the wet mixture, stirring until just combined. Be careful not to overmix.

Fold in Blueberries : Gently fold the blueberries into the batter, being careful not to crush them. Pour the batter into the prepared loaf pan, spreading it evenly.

Bake the Loaf : Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean. Allow the loaf to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

Prepare the Lemon Glaze : In a small bowl, whisk together the icing sugar, 1 tbsp lemon juice, and 1 tbsp milk until smooth and pourable. Adjust consistency with more milk or sugar as needed.

Glaze and Serve : Drizzle the glaze over the cooled loaf, letting it cascade down the sides. Slice and serve this luscious, citrusy loaf with a cup of tea or coffee.
