In a large bowl, combine the biscuit mix and cheese. With a fork, stir in milk just until moistened. Turn onto a floured surface; knead 10 times. Roll dough to 1/2-in. thickness; cut with a 2-1/2-in. biscuit cutter.
Place on an ungreased baking sheet. Brush with butter; sprinkle with paprika. Bake at 450° for 8-10 minutes or until golden brown.
