Using parchment paper, line a 9x5 bread loaf pan and set aside.
In a medium-sized bowl, add butter and sugar and beat until smooth. Add eggs one at a time, making sure to blend in between and then add in the vanilla.
Sift flour, salt and baking powder in a separate bowl and then add to sugar mixture a little bit at a time, alternating with the ½ cup of milk.
Using a fork, crush ½ cup of the blueberries and add to your batter. Fold in the remaining blueberries.
Pour batter into the prepared bread pan. Sprinkle sugar over the top and bake for about 65 - 70 minutes.
Remove from pan and allow to cool at least 30 minutes.
Notes
Glaze. Want one? Just whisk together 2 tablespoons melted butter, 1 1/2 cups powdered sugar (sifted), 1 teaspoon vanilla and 1 - 2 teaspoons heavy cream. Drizzle over warm bread, if desired.
