Mix the cream cheese, sweetener, cocoa powder and coffee extract in a bowl until thoroughly mixed and the sweetener has dissolved.
Place the mix into the freezer for 1 hour until it has set to a harder consistency
Using 2 cold spoons, form a ball of the mixture and place into a bowl filled with the chopped hazelnuts, rolling around in the nuts until fully coated
As each ball is formed, place onto chilled plate
Once all balls are formed, place in container and keep either in the freezer or in a very cold fridge (32-36°F) If eating from the freezer, give the balls 5 minutes to thaw slightly.
