Gather the ingredients. Preheat the oven to 350 degrees F (175 degrees C). Lightly grease an 8x4-inch loaf pan.
To make the batter: Beat sugar, butter, eggs, and lemon juice together in a large mixing bowl.
Combine flour, baking powder, and salt in a separate bowl. Stir into egg mixture alternately with milk. Fold in blueberries, nuts, and lemon zest. Pour batter into the prepared pan.
Bake in the preheated oven until a toothpick inserted into the center of the loaf comes out clean, 60 to 70 minutes. Cool bread in the pan for 10 minutes.
Meanwhile, prepare the glaze topping: Stir powdered sugar and lemon juice together in a small bowl until smooth.
Remove blueberry bread from the pan and drizzle with glaze. Continue to cool on a wire rack.
Enjoy!
