Preheat your oven to 170C and line a square cake tin with baking paper.
In a food processor blend the avocado, coconut oil, dates, nut butter and eggs together until smooth. Add cinnamon, almond meal, melted chocolate and cacao and blend until smooth. Stir through the macadamia nuts.
Pour into the prepared baking tray and smooth over to form an even layer. Pop into the oven for 30-40 mins until golden on the edges. Allow to cool for 30 minutes before slicing.
