To Make the Mint Filling:

1. Add the cashews to a blender or food processor and process until they form a powder. Add all remaining filling ingredients and process until smooth and creamy.
2. Scrape the mixture into a bowl, cover, and chill until firm enough to roll into balls. This takes about 4 hours in the fridge or 1 hour in the freezer; if you chill it too long, just let it sit at room temperature for a while before rolling.

To Shape the Patties:

1. Use a 1 1/2 tablespoon scoop to measure out the filling, roll it into balls, and then flatten each ball slightly into a thick disk.
2. Place the disks on a parchment-lined baking tray and refrigerate or freeze until the candy is chilled again.

To Coat the Patties:

1. Once the filling is chilled, melt the chocolate in a microwave-safe bowl in the microwave or in a double boiler.
2. Working with one candy at a time, place a candy in the chocolate coating, remove it with a fork, and place it on a baking rack or parchment-lined baking tray so the chocolate can set. Continue until all the candies are coated.
3. Let the chocolate set before serving.
