There is real chocolate in this, not just cocoa. Eight ounces of finely chopped semisweet melts into the milk over two hours and is the reason it drinks thicker and richer than a powder-based cup.
The first step is a small one that prevents the most common problem. Cocoa powder whisked with sugar into a single cup of milk makes a smooth paste; tipped straight into ten cups of dairy it would sit in lumps.
Why This Recipe Works
- Slaking the cocoa in one cup of milk first disperses it completely before the volume goes up.
- Two cups of half-and-half alongside six of whole milk give body without making it heavy.
- Whisking every thirty minutes keeps the melting chocolate moving so none of it settles and catches.
- Vanilla goes in after the cooking, where its aroma survives.
Ingredient Notes
- Semisweet chocolate
- Eight ounces, finely chopped. Chopped small so it melts evenly across the two hours.
- Whole milk and half-and-half
- Six cups and two cups. The half-and-half is what gives it body rather than making it a hot milk.
- Fine salt
- A quarter teaspoon. It is not detectable as salt — it sharpens the chocolate.
How to Make It
Slake the cocoa
Whisk the cocoa powder and sugar with 1 cup of the milk until smooth. Pour into the slow cooker with the remaining milk, half-and-half, chocolate and salt.
Two hours, whisking
Cover and cook on Low for about 2 hours, whisking every 30 minutes, until the chocolate is melted and the drink is steaming hot. Do not let it boil.
Vanilla off the heat
Stir in the vanilla.
Serve and top
Serve in mugs topped with whipped cream, mini marshmallows and chocolate shavings.
What Goes Into One Mug
The cooker holds eight mugs' worth. This is one of them, built in the order the recipe finishes it.
What goes into one mug
The hot chocolate
An eighth of the cooker: whole milk and half-and-half with cocoa, sugar, 8 oz of melted semisweet chocolate, salt and vanilla, steaming hot but never boiled.
Whipped cream
Spooned or piped over the surface. It goes on first so the other two toppings have something to sit on.
Mini marshmallows
Scattered over the cream rather than dropped into the drink, where they would sink and dissolve.
Chocolate shavings
Over the top, last. The visible finish on the mug.
Serve straight away while the cream is still holding and the drink is hot underneath it.
Success Tips
- Whisk the cocoa paste until it is genuinely smooth before it joins the rest.
- Set a timer for each thirty-minute whisk. Unattended dairy on Low will develop a skin.
- If it thickens more than you want, loosen it with warm milk added a little at a time.
Serving Ideas
Eight mugs, each topped with whipped cream, mini marshmallows and chocolate shavings.
Frequently Asked Questions
What happens if it boils?
Do not let it. Boiling dairy scorches and can split; Low for two hours is enough to get it steaming.
Mine is too thick. Can I fix it?
Loosen it with warm milk in small additions.
Can I use only cocoa powder?
The recipe uses both cocoa and eight ounces of chopped semisweet chocolate.
