Slow Cooker Hot Chocolate
There’s something comforting about a cup of hot chocolate that simmers low and slow. Using a slow cooker turns a simple drink into a velvety, almost dessert-like experience. The gentle heat melts the chocolate evenly, blends the dairy without scorching, and builds a richer flavor than stovetop versions. It’s perfect for cold evenings, holiday gatherings, game nights, or whenever you want a make-ahead treat that keeps warm for hours. This version is creamy, smooth and balanced, not too sweet, and easy to customize with spices or toppings. Once everything goes into the pot, the slow cooker does the rest.
Prep: 10 minutes
Cook: 2 hours on Low
Total: 2 hours 10 minutes
Serves: 6–8 mugs
Ingredients
4 cups whole milk
2 cups heavy cream
1 ½ cups semi-sweet chocolate chips
½ cup milk chocolate chips
¼ cup unsweetened cocoa powder
⅓ cup sugar (adjust to taste)
1 teaspoon vanilla extract
Pinch of sea salt
Optional: ½ teaspoon cinnamon, ⅛ teaspoon nutmeg, or 1–2 tablespoons instant espresso
Instructions
Grease the slow cooker lightly. A quick swipe of butter or oil spray keeps the chocolate from sticking to the edges.
Add the milk and cream. Pour both dairy components into the slow cooker. Stir to combine.
Add the chocolate chips. Scatter both types of chocolate chips across the surface so they melt evenly.
Whisk in cocoa powder. Sift the cocoa over the mixture to avoid lumps.
Add sugar and salt. These help balance the bitterness of the chocolate.
Cover and cook on Low. Let it warm for about 1 hour without opening the lid.
Stir well after 1 hour. The chocolate chips should be soft and partially melted. Whisk until smooth.
Cook for another hour. Keep the slow cooker on Low so the mixture heats gently.
Add vanilla. Stir it in right before serving for the freshest flavor.
Switch to Warm. Serve straight from the pot and let guests ladle their own mugs.
Tips
Use good-quality chocolate. The flavor depends heavily on the chocolate you choose, so pick one you’d enjoy eating plain.
Adjust sweetness early. After the first hour, taste and adjust sugar since flavors deepen as it cooks.
Whisk often once melted. This keeps the texture silky and prevents a chocolate film from forming.
Keep it on Warm, not Low. After it’s done, Warm keeps it smooth without overheating.
Avoid boiling. Chocolate scorches quickly. Low and slow is the safest method.
Add spices cautiously. Strong spices like cinnamon or nutmeg go a long way. Start small.
Use a handheld frother before serving. It creates a café-style foam and blends everything beautifully.
Offer toppings in bowls. Marshmallows, whipped cream, crushed candy canes, or shaved chocolate work well.
Make it thinner if needed. Add a splash of hot milk if you want a lighter consistency.
Store leftovers properly. Chill within 2 hours, then reheat gently on the stovetop the next day.
Variations
Dark Chocolate Version: Replace milk chocolate chips with extra dark chocolate for a more intense flavor.
White Hot Chocolate: Use white chocolate chips and skip the cocoa powder. Add extra vanilla.
Peppermint Hot Chocolate: Stir in ¼ teaspoon peppermint extract or melt a few candy canes directly in the pot.
Salted Caramel Hot Chocolate: Add ¼ cup caramel sauce and a pinch more sea salt.
Mocha Hot Chocolate: Add 2 tablespoons instant espresso or strong coffee for a café-style twist.
Hazelnut Hot Chocolate: Stir in 3 tablespoons hazelnut spread.
Spiced Mediterranean Blend: Add cinnamon, a pinch of cardamom and a touch of orange zest.
Peanut Butter Hot Chocolate: Melt in 2 tablespoons smooth peanut butter for a richer flavor.
Protein Hot Chocolate: Blend in 1–2 scoops of chocolate or vanilla protein powder after cooking.
Dairy-Free Version: Use coconut milk and almond milk. Replace chocolate chips with dairy-free versions.
Q&A
Can I use only milk instead of cream?
Yes, but the result will be thinner and less creamy.
Can I cook it on High?
It’s not recommended. High heat may split the dairy or burn the chocolate.
Can I make it less sweet?
Reduce sugar or use dark chocolate chips.
Can I keep it warm for several hours?
Yes. The Warm setting is perfect for parties. Just whisk occasionally.
Can kids drink this?
Absolutely. If adding coffee or strong spices, adjust for taste.
Can I freeze leftover hot chocolate?
It’s better to refrigerate and reheat. Freezing changes the texture.
Can I add marshmallows directly to the slow cooker?
You can, but they dissolve. It’s better to add them to each mug.
Can I use cocoa powder only?
You can, but chocolate chips give a richer flavor.
Can I add alcohol for adults?
Yes. Add Baileys, Kahlúa or rum at the end so it doesn’t cook off.
Can I double the recipe?
Yes, as long as your slow cooker is large enough. Cooking time stays the same.
