Preheat your oven to 350°F (175°C). Grease a loaf pan and set aside.

In a bowl, whisk together the flour, baking powder, and salt.

In a separate bowl, cream the butter and sugar until light and fluffy.

Add the eggs one at a time, beating well after each addition.

Mix in the vanilla extract.

Gradually add the dry ingredients to the butter mixture, alternating with the milk, beginning and ending with the dry ingredients.

Gently fold in the blueberries.

Pour the batter into the prepared loaf pan.

Bake for about 60 minutes, or until a toothpick inserted into the center comes out clean.

Allow the loaf to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
