Melt the cocoa butter and coconut oil in a bain-marie (heat very gently to prevent the chocolate from clumping together). This will take approx. 10 mins. Stir in the maple syrup and then the cocoa powder and remaining ingredients. Mix well to prevent clumps from forming. Taste and add a little more maple syrup if necessary. Pour the chocolate into a tray (e.g. brownie tray) lined with baking paper or cling film.
Sprinkle the topping over the melted chocolate, leave to cool.
Break into pieces to serve.
