Separate dough into 8 biscuits; place 4 inches apart on greased cookie sheets. Press out each to form 6-inch round. Spread 2 to 3 tablespoons sauce on each round. Sprinkle small cut-out pepperoni pieces over sauce. Sprinkle each round with Cheddar cheese; sprinkle each with mozzarella cheese. Top each with 4 pepperoni "hoof prints."
