How to make hot chocolate at home — and why the chocolate matters
Most hot chocolate people make at home starts with a powder and ends with something that's fine but not particularly memorable. A few small changes — starting with what you use as the base — make a significant difference to what ends up in the mug.
Here's how to make hot chocolate properly at home, and what to look for if you want a version that's genuinely worth the effort.
The difference between hot chocolate and hot cocoa
These two terms are often used interchangeably, but they're not the same thing.
Hot cocoa is made from cocoa powder — the dry, defatted solids left after most of the cocoa butter has been removed during processing. It's lighter, slightly acidic, and dissolves easily in hot liquid. Most instant hot chocolate products are essentially hot cocoa with added sugar and dried milk.
Hot chocolate is made from actual chocolate — melted into hot milk. Because real chocolate contains cocoa butter as well as cocoa solids, the result is richer, creamier, and has a fuller mouthfeel. It takes a little more effort than adding a spoonful of powder, but the difference in the cup is noticeable.
If you've ever had a really good hot chocolate — the kind that feels almost like a dessert — it was almost certainly made with real chocolate, not powder.
How to make hot chocolate with real chocolate
The basic method is straightforward:
- Heat your milk gently in a saucepan — don't boil it. Aim for around 70°C, which is hot but not scalding. Boiling milk affects the flavour and can cause the chocolate to seize.
- Add your chocolate — either chopped chocolate, chocolate chips, or a hot chocolate swirl — and whisk continuously until fully melted and combined.
- Taste and adjust. If you're using dark chocolate you may want a small amount of sugar or honey. Milk chocolate usually needs nothing added.
- Pour into a warmed mug and add toppings if using — marshmallows, a dusting of cocoa, a pinch of sea salt over dark chocolate.
The ratio is roughly 25–30g of good chocolate per 200–250ml of whole milk for a standard mug. For something thicker and more intense — closer to a continental-style drinking chocolate — increase the chocolate or reduce the milk slightly.
Why the chocolate you use matters
The quality of the finished drink is almost entirely determined by the quality of the chocolate you start with. This sounds obvious but it's worth being specific about why.
Cheaper chocolate — and most supermarket chocolate — often contains vegetable fat in place of some or all of the cocoa butter. When you melt this into milk, the result is thinner, less smooth, and has a slightly waxy aftertaste that becomes more noticeable once the drink cools slightly.
Chocolate made with real cocoa butter melts more cleanly into hot milk and produces a noticeably smoother, richer drink. Belgian couverture — the professional-grade chocolate used by chocolatiers — has a higher cocoa butter content than standard chocolate, which is part of why it behaves so well when melted.
You don't need to use couverture to make good hot chocolate at home. But using chocolate with a high cocoa butter content and no vegetable fat substitutes makes a real difference.
Hot chocolate swirls — the easiest way to do it properly
If you want to make great hot chocolate at home without measuring and chopping chocolate every time, a hot chocolate swirl is the most straightforward option.
A swirl is a solid portion of chocolate — shaped around a stick or spoon — designed to be stirred directly into hot milk until it melts. The portion is pre-measured, the chocolate is already good quality, and the whole process takes about two minutes.
Chez Emily's hot chocolate swirls are made from Belgian couverture chocolate at our workshop in Coolquay, Co. Dublin. Stir one into 200–250ml of hot milk, add marshmallows if you like, and it's done. Pick up a single swirl to try, or stock up with a box of 24 — a good option if hot chocolate is a regular habit or you're buying for a household.

Hot chocolate as a gift
Hot chocolate — particularly in swirl or gift set format — works well as a gift for almost any occasion where you want to give something consumable and a little more considered than a standard box of chocolates.
It travels well, keeps well, and requires no refrigeration. A hot chocolate gift set is a good option for:
- Christmas — the obvious season, but it works
- Teacher gifts — practical, universally liked, easy to wrap
- Thank you gifts — for someone who has a house and doesn't need more things
- New baby — something the parents can actually use once the chaos settles
- Winter birthdays — particularly for anyone who prefers experiences over objects
Our Hot Chocolate Gift Set includes a selection of swirls and marshmallows, presented ready to gift.
Milk or water — which is better for hot chocolate?
Whole milk. The fat content in whole milk combines with the cocoa butter in the chocolate and produces a noticeably creamier result than semi-skimmed or skimmed milk. Water works in a pinch but produces a thinner, less satisfying drink.
For a dairy-free version, oat milk is the best substitute — it has enough body to carry the chocolate well. Almond milk is thinner and produces a lighter result; coconut milk works but adds its own flavour, which either complements or competes depending on the chocolate you're using.
Our dark chocolate swirls — made from 70.4% cocoa Belgian couverture — are vegan friendly, so oat milk plus a dark swirl is a fully plant-based option that doesn't compromise on flavour. Browse the full hot chocolate range here.
