Instructions

• Pour 14 oz sweetened condensed milk, 1 cup milk chocolate chips, 1 cup coffee, and 4 cups white milk into a large saucepan.
• Place the saucepan over medium-low heat and begin stirring with a wooden spoon or heatproof spatula.
• Stir frequently and gently to prevent scorching, continuing to heat until the chocolate chips are fully melted and the mixture is smooth and steaming hot but not boiling — about 10–15 minutes.
• Remove the saucepan from the heat.
• Ladle the hot chocolate-coffee mixture into cups, top each serving with mini marshmallows, and serve immediately.
