Skip the crust: use cheesecake filling in a parfait and invent a whole new "layer cake." Mix the filling, then put some in a glass. Top with broken-up cookies (such as chocolate or vanilla wafers) or graham crackers, and add fresh fruit (such as raspberries or blueberries). Alternate layers. Refrigerate parfait for 30 minutes, and serve.
Chocolate cheesecake: make the crust with chocolate wafer cookies (10 ounces, or about 50 cookies) instead of graham crackers. Once you've mixed the filling, gently stir in 1 cup mini chocolate chips, and then fill the crust. Sprinkle more chips on top of the chilled cake.
