Gather Ingredients: Collect all your ingredients, including whole milk, heavy cream, cocoa powder, sugar, and chocolate chips – everything you need for this indulgent treat.

Combine Creams: Pour the whole milk and heavy cream into the slow cooker. Stir gently to mix them well; this combination will create a creamy base for your hot chocolate.

Whisk in Cocoa: Add the unsweetened cocoa powder and granulated sugar into the slow cooker. Whisk vigorously until the mixture is smooth, ensuring no lumps remain in your chocolatey goodness.

Mix in Chocolate Chips: Stir in the semi-sweet chocolate chips, making sure they are evenly distributed throughout the mixture. This addition will heighten the chocolate flavor, bringing richness to every sip.

Cook & Stir: Cover the slow cooker and set it on low heat. Let it cook for 2 hours, stirring occasionally. You’ll know it’s ready when the mixture is hot and all the chocolate chips have melted beautifully.

Serve Warm: Ladle the hot chocolate into mugs and enjoy it warm, with a dollop of whipped cream or marshmallows on top for that extra touch of sweetness.
