Combine everything in a small pan over medium heat, whisking until combined, the chocolate is melted and the milk is hot (but not boiling). Serve immediately. Alternatively, combine + heat everything except for the chocolate. Divide the chocolate between 2 mugs (so 2 tbsp. per mug). Then pour the hot chocolate on top. Stir and enjoy the melted chocolate as you sip on the hot chocolate. Follow for more cozy holiday hosting ideas!
