Combine cacao powder, almond milk, coconut sugar and salt in a medium saucepan and place over high heat.
Whisk to combine while cooking and bring to a boil.
When it comes to a boil it will rise, if it looks like it is going to boil over, take it off the heat quickly to stir and come back down, then return to the heat. Boil for about 3 minutes (starting the timer when bubbles start) until the coconut sugar has dissolved.
Let cool slightly then add vanilla and peppermint extract.
Transfer to a squeeze bottle and store in the fridge.
