Preheat oven to 350 F. Grease or line a muffin tin. Whisk wet ingredients, including apple. Stir in remaining ingredients just until evenly mixed. Divide among the muffin tins. Bake 19 minutes for large muffins or 12 minutes for mini muffins. The muffins are done baking when a toothpick inserted into the center comes out mostly clean. Let cool before removing from the tins. If you use liners and let them sit loosely covered overnight, the liners should peel off easily after a day.View Nutrition Facts
