Place cupcake liners in a 12-cup muffin tin.
Add crust ingredients to a food processor and mix on high until mixture is sticky and crumbly.
Divide crust evenly among the cupcake liners, about 1 heaping tablespoon for each cup. Press the mixture down into the cup to form a bottom crust, using fingers dipped in water if needed.
Wipe out processor and add in cheesecake ingredients. Mix on high until sugar dissolves and the mixture is smooth and creamy, about a minute or so.
Divide cheesecake mixture evenly among cups, about 2 heaping tablespoons for each. Smooth top using same method as crust.
Refrigerate for about 3 hours or freeze for about 1 hour, until cheesecake has set. Remove from cupcake liner when ready to eat. Top with fruit or jam.
Store in an air tight container in the refrigerator for up to 5 days, or freeze cups, store in a freezer bag, and let defrost on the counter for about 10 minutes when ready to eat.
