Preheat oven to 180 degrees Celsius.

Place the orange slices on a lined baking tray . Bake for approximately 30 minutes until lightly browned. Keep checking on them because when they brown, they brown rapidly. Set aside to cool.

Place all of the base ingredients into a food processor or Thermomix and blitz for approximately 20 seconds.

Pour the mixture into a lined cake tin (a shallow one works best). Press down with the back of a spoon. Place in the freezer for 10 minutes, then remove and press down with the back of a spoon again to make sure that the base is firm and evenly spread. Place in the refrigerator.

Drain the cashews. Place all filling ingredients into a food processor or Thermomix and blitz until completely smooth.

Remove the base from the fridge and pour the filling mixture evenly on top, smoothing down with the back of a spoon. Place in the freezer to set for approximately 2 hours.

Remove from the freezer.

Garnish with the baked orange slices and sprinkle with chocolate. Store in the refrigerator.
