Dark Hot Chocolate

Combine the milk and sugar in a saucepan and heat slowly over medium-low. In a small bowl, blend the cornstarch into ½ cup water and then whisk into the milk. Continue whisking until the mixture is hot; then add the cocoa powder and chocolate. Whisk until the chocolate has melted. Remove from heat and continue to whisk (or blend with an immersion blender) until smooth and slightly frothy, about 1 to 2 minutes. If desired, add peppermint schnapps. Ladle into individual mugs and serve. Serves 8.
