Yield: 12 muffins
Heat oven to 400 F. Grease bottoms of 12 medium muffin cups (2-3/4 inches in diameter) or line pan with paper baking cups. Mix all ingredients just until flour is moistened. Batter should be lumpy. Fill muffin cups 2/3 full. Sprinkle 1/4 teaspoon sugar over batter in each cup. Bake 18 to 20 minutes. Immediately remove from pan.
*If using self-rising flour, omit baking powder and salt.
