Line muffin tins with foil cupcake liners.
In a mixer, combine cream cheese, sugar, and vanilla until smooth. Add eggs and mix well. Put one vanilla wafer in each foil liner (place them upside down). Spoon batter over wafers, filling each 3/4 full. Bake at 325 degrees for 25 minutes. Cool the cheesecakes and then add your choice of pie filling or fresh fruit to the top of each cheesecake.
