Preheat oven to 400°F and line one muffin tin with paper cups.

Add flour, sugar, baking powder, and salt in large bowl and whisk until combined. Add blueberries to dry mixture.

Combine milk, oil, and beaten egg. Push up the sides of the dry ingredients to create a well in center of bowl, then pour in wet mixture.

Stir gently until all ingredients just moistened. Fill baking cups 2/3 full, then bake for 20 to 25 minutes. Makes 1 dozen.
