Preheat the oven to 180 °C.
To make the nut granola, combine all of the ingredients in a small bowl and toss to coat. Spread onto a baking tray. Bake for 10–15 minutes, until golden. Remove from the oven and set aside to cool.
Place one and a half punnets of the blueberries in a blender. Add the açai, banana and apple juice. Blend until smooth and creamy. Sweeten with maple, if desired.
To serve, pour the blueberry and açai smoothie into two wide shallow bowls. Arrange the granola, remaining blueberries and topping ingredients decoratively on top.
