How-to Make Healthier Hot Cocoa Mix

unsweetened cocoa powder, any kind you like (I prefer fair-trade raw organic cacao)

coconut sugar (or other granulated sugar, granulated monk fruit is a great option)

arrowroot, potato or tapioca starch

unsweetened, semi or bittersweet chocolate, roughly chopped

vanilla extract, powder or the seeds from a tiny segment of fresh vanilla bean

fine sea salt
