Add oat milk to a small saucepan over medium heat. Add in chopped chocolate, salt, and rosemary sprigs and whisk to combine as the milk begins to come to a slow boil. Let it boil for 3 minutes, then turn off the heat and add the vanilla extract. Let sit for 5 minutes, and enjoy! To make this non-vegan, add a dollop of fresh whipped cream to the top.
Please note, this makes about 4-5 servings of drinking chocolate. Drinking chocolate is richer and heavier than hot chocolate and should only be drunk in smaller amounts. This recipe does not add additional sweetener as the brand of oat milk used was lightly sweetened, but if you wanted yours to be sweeter, add 1-2 tbsp cane sugar. This is also a great shot to add to fresh Equal Exchange coffee to make a rich mocha.
Other delicious flavor pairings via extracts, spices, and rinds to replace the rosemary: cinnamon & chipotle, orange, mint, coffee, nutmeg, coconut, almond.
