In a medium pot, add the coconut milk and bring to a gentle simmer. Once it starts to burble/simmer, remove from heat and add the chocolate. Stir gently with a rubber spatula, making sure to scrape chocolate off the bottom of the pot so it doesn’t burn, until the chocolate is melted and mixture is smooth.
Transfer the chocolate mixture to a high-speed blender along with the beet (if using), coconut oil and salt. Blend on high until very smooth.
Transfer to a medium bowl or container and place in the fridge for at least one hour, or until solidified and scoop-able.
Use a small cookie scoop to scoop out individual truffles and place into a parchment lined plate. If you don’t have a small cookie scoop, use a tablespoon to scoop and use your hands to roll into balls. Your hands will get messy and the balls might not be perfect balls, but delicious all the same! Dust with cocoa powder. Place back in the fridge to solidify again (about 15 minutes). Store in an airtight container in the fridge.
You can also freeze them easily, but need to let them thaw out before eating.
