Preheat your oven to 350°F. Prepare two 8×4 bread pans by greasing them thoroughly. If you prefer one larger loaf, use a 9×5 loaf pan instead.
In a large bowl, combine the egg, milk, vegetable oil, and lemon juice. Beat them together until smooth and well incorporated.
In a separate bowl, mix the all purpose flour, sugar, baking powder, and salt. This helps ensure even distribution of dry ingredients.
Gradually add the dry mixture to the wet mixture, stirring gently. Be careful not to overmix; you want to maintain a light texture.
Once combined, fold in the blueberries and lemon zest delicately. This is where the magic happens as the blueberries burst with flavor.
Pour the batter evenly into the greased loaf pan(s). Use a spatula to smooth the top if needed.
Slide the pans into the oven and bake for about 50 to 55 minutes. Keep an eye on the time, especially if you’re using a larger loaf pan.
While the bread is baking, prepare the glaze. In a small bowl, stir together the powdered sugar, milk, lemon juice, and lemon zest until smooth and creamy.
Once the bread is baked, remove it from the oven and let it cool for a few minutes before spooning the glaze over the warm bread. Allow the glaze to set for at least 30 minutes before slicing.
Slice the loaf and serve. Enjoy the burst of flavors in every bite!
