Place your chocolate in a medium-sized mixing bowl.
In a separate small microwave safe mixing bowl, add in your coconut milk and microwave until warm but not boiling – around 20-30 seconds.
Immediately add your warm coconut milk to the chopped chocolate and loosely cover with a cooking lid or towel to trap the heat in. Leave for 5 minutes. After 5 minutes, lift the cover and use a mixing spoon to gently stir. Continue stirring until completely melted and smooth.
Stir in your vanilla extract.
Set your chocolate mixture in your refrigerator to chill uncovered for 2-3 hours, or until almost completely solid all the way through. You can use a knife to test this by dipping the edge of your knife into the chocolate mixture, it should come out mostly clean.
Once chilled and firm, prepare a small dish of cocoa powder for rolling. Measure out one tbsp-sized scoop, then use your hands to gently but quickly roll the chocolate into balls.
Toss in your cacao powder to coat and shake off excess, then set on a parchment-lined serving dish. Continue until all chocolate is scooped. Store covered in the fridge, enjoy!
