I found this on a vegan website during Finals week (aah, chocolate!). If you can make a cup of hot chocolate from scratch, you have all the ingredients for this recipe--it doesn't require confectioner's sugar, butter, or solid chocolate. The original recipe called for cornstarch, but I used besan (gram flour/chickpea flour) instead. I also didn't have vanilla, so I stirred in a packet of non-dairy, flavoured creamer at the end. Yum!
