Preheat the oven to 180 °C. Lightly grease with oil spray a 12 hole non-stick muffin pan or line with paper cases.
Sift flour and cinnamon into a large bowl.
Stir in sultanas and grated apple.
In a separate bowl, whisk the margarine, honey, milk, egg and vanilla. Add to the flour mixture and stir gently until the mixture is just combined; don’t overbeat or the muffins will become tough.
Spoon mixture into prepared muffin tins. Bake for 20 minutes or until lightly browned.
