1-First Step: Gather all your ingredients and a 6-quart crockpot to ensure everything is ready for quick assembly. Measure out 6 cups of whole milk, two 12-ounce cans of evaporated milk, 2 cups of chocolate chips, 2 teaspoons of vanilla extract, and 3 cups of heavy cream. This step, which takes about 5 minutes, sets the stage for a seamless cooking process and helps avoid any last-minute rushes.

2-Second Step: Add all the ingredients except the marshmallows to your crockpot. Pour in the milk, evaporated milk, chocolate chips, vanilla extract, and heavy cream, then stir gently to mix them together. This initial blend ensures even distribution and helps the chocolate melt uniformly, preventing any scorching during cooking.

3-Third Step: Set your crockpot to low and cook for 3-4 hours, stirring often during the first hour to melt the chocolate evenly. If you want quicker results, start on high for the first 30 minutes then switch to low. Keep an eye on it to maintain that perfect creamy texture, making this crockpot hot chocolate recipe adaptable to your schedule.

4-Fourth Step: In the final 30 minutes, stir in the large and mini marshmallows to let them melt into the mix. This adds a delightful gooey element and enhances the flavor, so taste and adjust as needed for sweetness or thickness.

5-Fifth Step: Once the hot chocolate is steaming hot and smooth, ladle it into mugs and top with extras like whipped cream or peppermint sticks. For those without a crockpot, use a large pot on low heat, stirring frequently until everything melts and heats through.
