For the base: add your hazelnuts to your food processor and blitz until turns into a fine meal.
Add your dates and salt and blitz again until the mixture becomes sticky
Press mixture down on the base of lightly greased square slice tin (I use coconut oil spray). Set aside
For the filling: add all your ingredients to a blender and blend until smooth. You may need to add a little more water if your blender is having trouble.
Pour filling over base and even out with a spatula
Freeze overnight or for at least 4 hours
Cut into slice squares and decorate with chopped hazelnuts and desiccated coconut.
You may need to allow it to defrost slightly before cutting
