Soak your dates in warm water for at least 15 minutes until dates are soft (drain but save the water)
In a blender, blitz all the ingredients (apart from toppings). The mixture should hold together, if too dry add 1-2 more dates/water from dates. If too wet, add more oats slowly.
In a prepared muffin tray, add 1-2 tbsp of the mixture and press down firmly.
Top with melted chocolate and chopped pistachios.
Refrigerate until set!
