Step 1: Add All Ingredients to the Slow Cooker

In your slow cooker, combine the milk, heavy cream, semi-sweet chocolate chips, sweetened condensed milk, cocoa powder, vanilla extract, and a pinch of salt. Stir everything together to help dissolve the cocoa powder and mix the ingredients evenly.

Step 2: Set the Slow Cooker

Cover the slow cooker and set it to low heat. Let the hot chocolate cook for 2 hours, stirring occasionally. The chocolate chips will melt into the milk and cream, creating a smooth, velvety texture. Keep an eye on it and give it a stir every 30 minutes or so to ensure it doesn’t burn or form a skin on top.

Step 3: Adjust the Flavor

Once the hot chocolate is fully heated and the chocolate has melted, taste it and adjust the sweetness to your liking. You can add more sweetened condensed milk or a bit of sugar if you like it sweeter.

Step 4: Serve and Enjoy

Once it’s ready, give it one last good stir, then ladle the hot chocolate into mugs. Top with whipped cream, marshmallows, a sprinkle of cinnamon, or any of your favorite toppings.
