⅓ cup melted butter
2 large eggs
3 tablespoons lemon juice
1 ½ cups all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
½ cup milk
1 cup fresh or frozen blueberries
½ cup chopped walnuts
2 tablespoons grated lemon zest
¼ cup white sugar
2 tablespoons lemon juice
Preheat the oven to 350 degrees F (175 degrees C). Lightly grease an 8x4-inch loaf pan.
Prepare the bread 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 sugar and lemon juice together in a small bowl until smooth.
Remove bread from the pan and drizzle with glaze. Continue to cool on a wire rack.
