Notes
The sweetener is optional. I use it because I prefer extra-dark chocolate. But if you don't mind the slight bitterness of extra-dark chocolate, or if you're using sweeter chocolate, you can leave the sweetener out.
If you add a sweetener but prefer one other than stevia, I recommend a powdered sweetener. A granulated sweetener could cause the chocolate to feel grainy.
You can replace the avocado oil with coconut oil, melted butter, or melted ghee.
You can store the leftovers, but not for long. This is the only drawback to this recipe. You need to make this dessert on the day you plan on eating it. Fresh mint leaves don't keep for more than a day, two at the most. So, if you do have leftovers, place them in the fridge in an airtight container, but plan on finishing them up quickly.
