Heat oven to 400ºF. Grease bottoms only of 12 regular-size muffins cups, or line with paper baking cups.
In large bowl, beat milk, oil, yogurt and egg using wire whisk or fork. Stir in remaining ingredients except blueberries, until flour is moistened. Gently stir in blueberries. Divide batter evenly among muffin cups.
Bake 16 to 18 minutes or until golden brown. Cool 5 minutes; remove from pan.
