Preheat oven to 375 degrees. Spray a muffin tin with nonstick cooking spray. Combine flour, sugar, baking powder and salt in a medium mixing bowl. Whisk together milk, oil and egg. Add to dry ingredients. Mix just until blended. Do not over mix. Batter will be lumpy. Spoon batter into muffin cups until 2/3 full. Bake 15-20 minutes until starting to brown. Makes 12.
