Instructions

• Pour 4 cups white milk, 1 cup coffee, and 14 oz sweetened condensed milk into a large saucepan; stir to combine.
• Add 1 cup milk chocolate chips to the saucepan and stir so the chips are distributed evenly.
• Place the saucepan over medium-low heat.
• Heat gently, stirring frequently (every 1–2 minutes) to prevent sticking, until the chocolate chips are fully melted and the mixture is smooth and hot. Do not let it come to a rolling boil; gentle steaming and small bubbles at the edge are enough. This typically takes about 10–20 minutes.
• Remove the pan from the heat once the mixture is smooth and hot.
• Pour into cups and top each serving with mini marshmallows.
• Serve immediately.
