1Heat oven to 400°F. Grease bottoms only of 12 regular-size muffin cups (2 1/2x1 1/4 inch) with shortening, or line muffin cups with paper baking cups.
2In large bowl, beat milk, oil, sugar, lemon peel and eggs with fork or wire whisk. Stir in remaining ingredients just until flour is moistened. Divide batter evenly among muffin cups.
3Bake 14 to 16 minutes or until toothpick inserted in center comes out clean. Immediately remove from pan. Serve warm.
