Preheat your oven to 350℉ (175℃) and grease a loaf pan (8.5×4.5×2.5 inches) with either butter or cooking spray, then dust it with a little flour.
In a large mixing bowl, combine 1½ cups of all-purpose flour, 2 teaspoons of baking powder, and ½ teaspoon of salt. Whisk them together to ensure the leavening agent is evenly distributed.
In another bowl, whisk together 1 cup of Greek yogurt, 1 cup of sugar, 3 large eggs, 2 tablespoons of lemon zest, 1 teaspoon of vanilla extract, and ½ cup of vegetable oil until smooth and well combined. The mixture should be creamy and slightly thick.
Now, pour the wet ingredients into the dry ingredients and gently mix with a whisk until just combined. Be careful not to overmix; you want the batter to be fluffy!
In a small bowl, toss the 1½ cups of blueberries with 1 tablespoon of flour. This helps keep the blueberries suspended in the batter instead of sinking. Gently fold the blueberries into the batter with a spatula.
Pour the batter into the prepared loaf pan, spreading it evenly with a spatula. It should be nice and smooth on top.
Bake in the preheated oven for about 50 minutes or until a toothpick inserted into the center comes out clean. Keep an eye on it; all ovens vary!
While the loaf bakes, prepare the lemon syrup. In a small saucepan over medium heat, combine ⅓ cup of lemon juice and 1 tablespoon of sugar. Cook just until the sugar dissolves and the mixture becomes clear. Set aside to cool.
For the glaze, whisk together 1 cup of icing sugar, ¼ cup of lemon juice, 1 teaspoon of vanilla extract, and enough milk to achieve your desired consistency. It should be pourable but not too runny.
Once the loaf is done, take it out of the oven and allow it to cool in the pan for about 10 minutes. Carefully remove it from the pan and place it on a wire rack over a baking sheet.
Using a skewer or toothpick, poke holes in the top of the loaf, then pour the lemon syrup all over the loaf, allowing it to soak in and add flavor.
Let the loaf cool completely. Once cooled, drizzle the lemon glaze over the top, slice, and serve. Enjoy each bite of this delightful Lemon Blueberry Loaf!
