1. Preheat oven to 400°F. Coat a 12-cup muffin pan with cooking spray or line muffin cups with paper liners.
2. In a medium bowl, combine flour, baking powder, sugar, and salt. In a large bowl, beat eggs, milk, oil, and vanilla for 1 minute on medium. Add flour mixture. Beat just until no streaks of flour remain—do not overmix!
3. Spoon batter into muffin cups. Bake for 18 to 20 minutes or until tops of muffins spring back when pressed lightly. Transfer muffins to a rack to cool slightly.
Makes 1 dozen.
