Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan and set aside. I like to use cooking oil then coat with flour. You can use parchment paper too
In a large bowl, whisk together the flour, baking powder, sugar, and salt.
Stir in the blueberries and lemon zest until the berries are lightly coated in the dry mix.
In another bowl, beat the eggs, then add the milk, vegetable oil, and lemon juice. Mix well.
Combine wet and dry ingredients. Pour the wet mixture into the flour mixture and stir just until moistened—don’t overmix.
Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean. (Start checking at 50 minutes.)
While the bread bakes, make the glaze: In a small bowl, stir together lemon juice, sugar, and zest until the sugar dissolves.
When the bread is done, remove it from the oven and brush or drizzle the glaze over the top while it’s still warm.
Cool in the pan for 10 minutes, then transfer the loaf to a wire rack to cool completely. Slice, serve, and enjoy!
