Preheat your oven to 350°F (175°C).
Toss the blueberries with 1 tablespoon of flour and 1 teaspoon of sugar.
In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt.
In a separate bowl, whisk together the granulated sugar, vegetable oil, eggs, milk, and vanilla extract.
Pour the wet mixture into the dry ingredients and stir gently until just combined.
Gently fold the floured blueberries into the batter.
Grease your loaf pan or line it with parchment paper and pour in the batter.
Bake for 50-60 minutes, or until a toothpick comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
