Place your coconut milk, honey, and coconut butter into a saucepan. Heat over medium-high heat and whisk constantly using a hand blender or a milk frother until smooth and bubbly.
Remove from the heat.
Immediately add your chopped chocolate and allow it to sit for 5 minutes in the hot milk mixture, until it melts.
Add the vanilla then whisk until smooth and the chocolate is fully melted. Your ganache should already be considerably thick at this point, see photos for reference.
Pour your ganache over the nut base in the tart pan.
For best results refrigerate for 24 hours (or at least overnight). You may choose to lightly sprinkle your tart with sea salt before serving as I did in the photos.
Slice and enjoy!
