In a large bowl, combine dry ingredients. In another bowl, beat the eggs, sour cream & butter. Stir into dry ingredients just until moistened. Fold in apples. Fill greased or paper-lined muffin cups two thirds full.

For topping, combine sugar, flour and cinnamon. Cut in butter until mixture resembles coarse crumbs. Sprinkle a rounded teaspoonful over each muffin.
