This isn’t your average cocoa. No. This is serious hot chocolate.

Glossy, indulgent, almost pudding-like, and made with real chocolate. It’s so rich, it probably owns a yacht.

Key Ingredient notes and substitutions

Milk

We use full-fat (whole) milk. Semi-skimmed works as a decent alternative, but skimmed milk just won’t cut it – it’ll be too thin and disappointing.

You can also use plant-based milk like oat, almond or soy. Just choose a barista-style or full-fat version for that same creamy texture and richness.

Cornstarch

We’re adding just enough cornflour to help thicken the chocolate. Don’t worry, you won’t taste it!

Don’t let it boil once the cornstarch is added

Overcooking can cause the thickener to break down and ruin that dreamy texture. Keep it at a gentle simmer.

Chocolate

Both milk chocolate and dark chocolate work wonderfully. Choose your favourite, but note that dark chocolate can make it a little stronger and might not be as popular with kids.

Use good-quality chocolate and cocoa

This isn’t the time for shortcuts. Cheap chocolate = sad cocoa. Brands like Callebaut, Valrhona or Ghirardelli make a big difference.

Cocoa powder

For best results, use a high-quality Dutch-processed, 100% unsweetened cocoa powder like Valrhona, Callebaut or Ghiradelli. The quality makes a noticeable difference.

White sugar

You can also use caster sugar or light brown sugar as alternatives.

A pinch of salt goes a long way

Just a small pinch enhances the chocolate’s depth and rounds out the sweetness. Don’t skip it!

Step-by-step instructions

Adding a dash of milk to the cornstarch in a small white bowl.

1. In a small bowl, combine the cornflour with about 3 tablespoons of the milk. Whisk until smooth and lump-free, then set aside.

2. In another small bowl, whisk together the cocoa powder, sugar and a pinch of salt until well combined.

3. Heat the milk in a saucepan over medium heat until it begins to simmer.

4. Reduce the heat to low and whisk in the cocoa and sugar mixture. Continue whisking for 1 minute until the sugar dissolves and the mixture is smooth and lump-free.

5. Stir in the cornflour slurry and whisk vigorously for 1 minute until the mixture thickens slightly. Don’t let it boil.

Top Tips

Keep whisking: Whisk vigorously and continuously when adding the cornflour slurry to prevent lumps.

If lumps form, a quick blend with a stick blender will make the hot chocolate smooth again.

Don’t let it boil: Overheating the milk can scald it or cause it to develop a skin. Keep the heat low and consistent after the initial boil.

Warm the mug: Pour hot water into your mug and let it sit while you prepare the drink. Empty it before pouring in your hot chocolate to keep it warm longer.

Serving suggestions

This recipe makes one gloriously indulgent serving, or go the sophisticated European route and divide it into two to three small cups, just like the Italians do with their cioccolata calda (perfect with biscotti!).

It’s intensely rich, so smaller portions are perfect if you’re pairing it with dessert or want a little portion control.

Quick tip

It’s dreamy alongside something salty like pretzels, salted nuts, buttered crackers or even a cheeky cheese straw. Sweet meets salty = magic.

Top with toasted marshmallows or stir in peanut butter for a nutty flavour.
Hook candy canes on the rim for a festive touch.

Storage and Reheating

Leftover thick hot chocolate? Lucky you!

Store it in an airtight container in the fridge for up to 3 days. As it chills, it will thicken even more. Don’t worry, that’s totally normal (and quite delightful if you like it almost spoonable).

To reheat, transfer it to a saucepan and warm gently over low heat, stirring often. Add a splash of milk or cream to loosen the consistency to your liking. Avoid boiling it, high heat can cause the chocolate or milk to split.

Prefer the microwave? Heat in short bursts (20–30 seconds), stirring in between, and don’t forget that splash of milk.

Quick tip

If it looks a little lumpy after reheating, a quick whisk or blitz with a stick blender will bring back that silky-smooth texture.

FAQs

Why does my hot chocolate sometimes get too thick, or turn pudding-like?

This is normal! The cornstarch continues thickening even off the heat.

If it becomes too thick, stir in a splash of hot milk while reheating to reach the ideal consistency.

How do I prevent lumps during cooking?

– Always whisk cornstarch with a little milk first to make a smooth slurry.

– Add the slurry to warm (not boiling) milk, stirring in one direction.

– If lumps appear, remove from heat and whisk briskly, or blitz briefly with a stick blender.

Can I skip cornstarch and add more chocolate instead?

Yes, you can – It will just not be as thick. Add a fair bit more chocolate for a thicker consistency.

Why doesn’t oat/almond milk always work?

Plant-based milks vary in fat and protein.

Barista-style versions are richer and better for thick hot chocolate. Regular almond or soy milks tend to produce thinner drinks with less creaminess.

How thick should it be? Should it coat the spoon?

Aim for a texture that clings to the back of a spoon, pudding-like but still pourable.

If it holds shape or becomes too stiff, thin it slightly with milk while it’s still warm.
