To make the crust add the dates, cashews, and salt to the bowl of a food processor and process until a loose ball forms. If your dates were a little dry you might need to add a tablespoon or so of warm water and then process again until the mixture starts to come together.
Add about a tablespoon of the crust to 6 glasses/mason jars/containers (about 1 cup in size) and use a spoon to press it into the bottom of the jar.
To make the cheesecake: place all of the ingredients in the bowl of a food processor and process until smooth (about 1 minute).
Spoon the cheesecake mixture evenly into the 6 jars. Use a spoon to smooth out the top.
Cover and refrigerate for at least 2 hours before serving. Serve with your choice of toppings (like berries or other fruit).
