Line an 8x8 inch square baking dish with parchment paper.
In a medium pot, combine the maple syrup and coconut cream. Bring to a boil over high heat and boil for 8-10 minutes, or until thickened to a caramel-like sauce.
Remove from heat. Stir in the peanut butter and vanilla extract until smooth. Then, stir in the toasted coconut flakes until evenly coated.
Press the coconut mixture firmly and evenly into the prepared baking dish.
Transfer the dish to the freezer and freeze until firm, about 30 minutes to 1 hour.
Melt the dark chocolate in the microwave in 30-second intervals until smooth. Let it cool for 10 minutes.
Cut the frozen coconut base into 16 bars. Dip each bar into the melted dark chocolate, coating completely. Top with cocoa nibs, coconut, nuts, or dried fruits as desired.
Let the chocolate set up, about 10 minutes. Keep stored in the fridge.
