Preheat oven to 325°.
To prepare crust, combine the first 3 ingredients in a small bowl. Press about 1 1/2 teaspoons crumb mixture into the bottom of each of 48 mini muffin cups coated with cooking spray. Bake at 325° for 5 minutes.
To prepare the filling, place 6 candies, fat-free cream cheese and the next 6 ingredients (fat-free cream cheese through sour cream) in a food processor; process until smooth. Stir in minichips and peppermint extract. Divide the filling evenly among prepared crusts. Bake at 325° for 12 minutes or until done. Cool in pans on a wire rack for 30 minutes. Remove mini cheesecakes from pans, and cool completely. Top each mini cheesecake with 1 teaspoon whipped topping. Crush the remaining 6 candies; sprinkle the crushed candies and chocolate sprinkles over the cheesecakes.
