In a small slow cooker (you can use a double boiler too), melt your chocolate on low, stirring once or twice as it melts.
When melted, stir in the coconut oil and melt fully.
Stir in the remaining ingredients and mix well.
Pour the chocolate into chocolate bar molds and set in the fridge. Once they are a little solid, you can move them to the freezer if you need them to harden faster.
Remove from mold and keep in the fridge or freezer at all times.
