In a large bowl, combine the first eight ingredients. In another bowl, beat the egg, buttermilk, and pepper sauce. Stir into dry ingredients just until moistened. Fold in the ham, cheddar cheese, and process cheese.
Fill greased muffin cups three-fourths full. Top each muffin with about 1 teaspoon Parmesan cheese and 1/4 teaspoon butter. Combine the paprika, parsley, and pepper; sprinkle over muffins.
Bake at 450° for 10-14 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing from pans to wire racks. Serve warm. Refrigerate leftovers. Yield: 14 muffins.
