Step 1

Preheat oven to 350° F (175° C). Grease and flour an 8 1/2 x 4 1/2 inch loaf pan.

Step 2

Mix flour, sugar, baking powder, and salt in a large bowl. Stir milk, oil, egg, and vanilla extract into flour mixture until batter is just blended.

Step 3

Combine washed and dried blueberries with 1 tsp of flour and gently fold them into the batter. Pour batter into prepared loaf pan. Sprinkle one tablespoon of sugar over the batter.

Step 4

Bake in the preheated oven until a toothpick inserted into the center comes out clean, 60 to 70 minutes. Let cool in the pan for 15 minutes, then transfer to a cooling rack and let cool completely.
