Preheat your oven to 350°F (175°C) and prepare your 9x5-inch loaf pan by greasing it lightly.

In a large bowl, whisk together flour, baking powder, and salt until thoroughly combined.

In another bowl, cream together softened butter and granulated sugar using an electric mixer until light and fluffy (about 3-5 minutes).

Beat in eggs one at a time until well incorporated, then add lemon zest and juice.

Gradually add your dry mixture into the wet ingredients while mixing on low speed until just combined.

Gently fold fresh blueberries into the batter using a spatula.

Pour the batter into the prepared pan and bake for 50-60 minutes or until golden brown.

While the loaf cools down, whisk powdered sugar with fresh lemon juice until smooth and drizzle over the cooled loaf.
