Apple Streusel Muffins

In a large bowl, combine dry ingredients. In another bowl, beat the eggs, sour cream and butter. Stir into dry ingredients just until moistened. Fold in apples. Fill greased or paper-lined muffin cusp 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. Bake at 400 degrees F for 18-20 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing from pans to wire racks. Serve warm.
