1Heat oven to 400°F. Place paper baking cups in 12 regular-size muffin cups, or grease bottoms only of muffin cups.
2In small bowl, mix yogurt and oats. In large bowl, mix egg, oil and brown sugar. Stir in flours, baking soda, cinnamon, salt and yogurt mixture (batter will be lumpy). Gently stir in blueberries. Divide batter evenly among muffin cups.
3Bake 18-20 min or until golden brown. Immediately remove from pan.
