Add the desiccated coconut, raspberries, vanilla extract, and maple syrup to a food processor and pulse until the mixture comes together for a few seconds.
Press the mixture into the loaf tin and place it in the freezer for 1-2 hours until solid. Slice into 16 even-sized bars and place them back in the freezer while you melt the chocolate using your preferred method.
Spear each bar using two forks and dip it in the melted chocolate before placing it on a baking sheet lined with baking paper.
Once each bar has been coated in chocolate, place the bars back into the freezer to set.
