In a large bowl, beat together half of the butter, sugar and eggs until smooth. Mix in vanilla. Add chopped apples and gradually blend in the flour mixture. Stir only until moistened. Spoon the mixture into prepared muffin pan.
In a small bowl, mix brown sugar, flour and cinnamon. Cut in butter until mixture is like coarse crumbs. Sprinkle over tops of mixture in muffin pan.
