In a large bowl add the granola, nuts and cinnamon and combine.
Place the peanut butter in a sauce pan and heat over a low heat until it loosens up. Remove from the heat and mix in the maple syrup. Add this to the granola, mix well and make small walnut sized bites. Place them on a baking tray.
Melt the chocolate in a bowl over a pan of simmering water, stirring regularly. Add the coconut oil and mix well.
Coat the bites with the melted chocolate and leave them to set.
