Preheat oven to 425° F. Place paper liners in a muffin tin and set aside.
Divide batter among paper-lined muffin tin, filling each cup about three-quarters full. Sprinkle additional sugar on top if desired. Bake at 425° F for 5 minutes, then reduce temperature to 375° F and bake for an additional 10-12 minutes or until the muffin tops are light golden brown and a toothpick inserted in the center comes out with little to no crumbs.
Allow muffins to cool in the pan for 5 to 10 minutes before removing and serving.
