Crush the graham crackers and mix with the melted butter. The mixture should be like sand. Line a cupcake pan with some foil liners. Press a tablespoon of graham crackers into the liners and press down and out. Chill in the fridge.

Prepare the cheesecake filling. Preheat the oven to 350 degrees F. Beat the cream cheese until smooth, adding the sugar, vanilla, and egg. Fill the cupcake liners 2/3 full and bake for 20 minutes.

Cool for 30 minutes and then refrigerate for 2 hours. Remove from the liners and top with the jelly or jam.
