Preheat the oven to 160°C/ 320°F.
In a large mixing bowl, whisk together the clementine juice, almond butter, cocoa powder, maple syrup, cinnamon and a pinch of salt.
Stir in the oats and almonds and mix well to combine.
Press the mixture onto a half sheet pan, keeping all the granola as one mass to allow clumps to form.
Bake for 20 minutes, breaking up the granola halfway through cooking to ensure cluster formation and even browning.
Leave to cool COMPLETELY on the baking tray before stirring in the chocolate chunks. Enjoy!
