Quick answer
For a hot chocolate bar, keep a big batch of real hot chocolate warm in a slow cooker and set out mugs and 8 to 12 toppings in small bowls: marshmallows, whipped cream, crushed candy canes, chocolate shavings, caramel and a few grown-up add-ins. Plan 1½ cups of hot chocolate per guest; our slow-cooker recipe serves 8 and doubles easily.
How much hot chocolate per guest
Plan 1½ cups (12 oz) per guest; most people go back for a second, smaller mug.

Setup checklist
- Put the slow cooker at one end on WARM with a ladle and a small plate under it.
- Mugs next, then toppings from heaviest to lightest: drizzles, crunch, marshmallows, whipped cream last.
- One spoon per bowl, plus a cup of stirring spoons or peppermint sticks.
- Napkins, a trash bowl for wrappers, and a jug of water for kids.
- Label everything, especially nuts and the adult add-ins (free printable signs below).
Make it ahead
Make the cocoa up to 2 days ahead, chill it, and reheat it in the slow cooker on LOW for 2 to 3 hours, whisking once an hour. Fill topping bowls the morning of the party and cover them; add the whipped cream and drizzles just before guests arrive.
Dairy-free and lighter options
- Dairy-free: use oat milk and dairy-free chocolate chips; oat milk keeps it the creamiest.
- Lighter: use 2% milk and swap half the chocolate for 2 extra tbsp cocoa: about 230 calories a cup.
- High-protein: our high-protein hot chocolate has 25 g protein per mug.

FAQ
How long can hot chocolate stay in a slow cooker?
Up to 4 hours on WARM. Whisk it every hour so a skin doesn't form, and keep it below a simmer so the milk doesn't scorch.
What is the difference between hot chocolate and hot cocoa?
Hot cocoa is made from cocoa powder; hot chocolate is made from melted chocolate. Our recipe uses both: chocolate for body, cocoa for a deeper flavor.
How many toppings does a hot chocolate bar need?
8 to 12 is plenty for up to 24 guests. More than that slows the line down.
Can I use hot cocoa mix instead?
Yes: about 1 packet per cup of hot milk. Real chocolate tastes richer, but mix is easiest for a big crowd.
