2 T Butter or margarine
1 c Packaged biscuit mix

Make Coffeecake: Cut butter into tiny pieces over biscuit mix in medium bowl. Toss lightly with fork until butter is coated. Make a well in center. Pour in milk and cinnamon-sugar, stirring with fork just until mixture is moistened. Turn dough into a lightly greased and floured 8-inch shiny, heavy skillet. With floured hands, pat down evenly into the skillet. Cook, covered, over very low heat, 12 to 15 minutes, or until a cake tester or wooden pick inserted in center comes out clean.
For Topping: Spread the coffeecake with 2 Ts butter or margarine. Then sprinkle 1 ts prepared cinnamon-sugar over all of it. Cut into quarters, and serve warm.
