Ube hot chocolate: the purple hot chocolate recipe

Un chocolat chaud violet, plus doux qu'un chocolat classique : lait moussé, chocolat blanc et poudre d'igname violette, en cinq minutes.

All it takes is one cool evening for the craving to come back: a mug in your hands, something thick, hot and comforting. Ube hot chocolate takes that classic and tips it into a colour nobody expects — a deep purple, obtained without a single drop of colouring. Ube powder, the purple yam from the Philippines, brings both the shade and a mild, vanilla-like, faintly nutty flavour that pairs remarkably well with white chocolate and hot milk. The result is not a classic hot chocolate with colour added: it is a drink in its own right, rounder and less bitter than a traditional dark chocolate, and considerably more photogenic.

This recipe is made in one saucepan, in ten minutes, with simple ingredients. We give you the exact proportions for two large mugs, the no-lump method that changes everything, four tested variations (including a fully plant-based one) and the mistakes that turn the purple grey. At Ubedia we work exclusively with the Kinampay variety from the Visayas, dried and then ground with no additives — that purity is what allows the colour to hold up to heat.

The ingredient for this recipe: Natural Ube Powder 200 g — 16.90 €, 100 % purple yam, no additives.

Why make your own ube hot chocolate?

Shop-bought hot chocolate almost always follows the same pattern: cocoa, plenty of sugar, often a thickener. By starting from a homemade base and working in ube powder, you take back control of three things. First the colour: the purple comes from the tuber itself, not from added colouring, and it stands up very well to gentle heating. Then the sugar: you decide how much, and ube already brings a natural sweetness that lets you use less than in a classic recipe. Finally the texture — perhaps the most interesting point of all.

Ube is a tuber, so it is rich in starch. When heated, that starch behaves like a natural binder: it thickens the drink slightly and gives it the velvety body you look for in a good hot chocolate, with no need for cornflour or cream. This is exactly what sets an ube hot chocolate apart from a simple ube latte: the latte stays light and foamy, the hot chocolate is dense and coating, made to be sipped slowly.

Ingredients for 2 large mugs

Allow 5 minutes of preparation and 5 minutes of cooking.

The white chocolate is not there out of gratuitous indulgence: its cocoa butter brings the fat and the gloss, and its neutrality keeps the ube flavour front and centre. Dark chocolate would completely overwhelm the tuber and give an unappealing purplish-brown colour. If you still want a cocoa note, allow 10 g of unsweetened cocoa at most, no more. To place these quantities alongside your other preparations, our ube powder dosage guide sets out the benchmarks container by container.

The recipe step by step

  1. In a bowl, mix the ube powder with the 2 tablespoons of cold milk until you have a smooth paste with not a single lump. This step takes thirty seconds and determines the whole final texture.
  2. Pour the rest of the milk into a saucepan with the pinch of salt. Heat over medium-low heat until small bubbles appear around the edges, without ever letting it boil.
  3. Take off the heat, add the chopped white chocolate and let it melt for 1 minute without stirring, then whisk until the mixture is perfectly smooth.
  4. Return to low heat and whisk in the ube paste vigorously. The colour turns purple immediately.
  5. Keep over low heat for 2 to 3 minutes, whisking regularly: the mixture thickens and coats the back of a spoon. Never take it past a bare simmer.
  6. Off the heat, add the vanilla, taste, and only add sugar if you need to — the white chocolate already brings plenty.
  7. Pour into two mugs warmed beforehand with hot water. Serve straight away.

The no-lump method, in detail

This is the only real trap in this recipe. Thrown straight into hot milk, ube powder instantly forms little beads whose centre stays dry: the starch on the surface gels and traps the powder inside. Cold milk, on the other hand, hydrates the powder before the starch reacts — hence the paste made in advance.

Three fallback solutions if the problem comes up anyway. Blitz the mixture with a hand blender for ten seconds, which works every time. Strain it through a fine sieve before serving, which will cost you a little material. Or, beforehand, sift the ube powder together with the sugar: the sugar mechanically separates the particles and limits clumping. The same logic applies to all our ube drinks, hot and cold alike.

Four tested variations

The plant-based version (coconut). Replace the whole milk with 400 ml of oat milk and 100 ml of coconut milk, and the white chocolate with 70 g of plant-based white chocolate. The oat brings the roundness, the coconut the fat. It is the variation closest to the Filipino spirit, where ube and coconut always go together — the same pairing found in our coconut ube powder, which also lets you skip the coconut milk step.

The spiced version. Add a cinnamon stick, two crushed cardamom pods and a slice of fresh ginger to the milk right at the start of heating. Let it infuse for five minutes, remove the spices, then carry on with the recipe. Cardamom in particular works very well with the vanilla note of ube.

The extra-creamy version. Replace 100 ml of milk with 100 ml of full-fat liquid cream and reduce the white chocolate to 60 g. You get a consistency close to Italian-style hot chocolate, to be served in small cups rather than in mugs.

The iced version. Make the recipe as normal, let it cool completely, then pour it over ice cubes. The drink thickens as it cools: loosen it with an extra 100 ml of cold milk. For a distinctly more dessert-like version, blend the whole thing with two scoops of vanilla ice cream — at which point you cross over into our ube milkshake.

The mistakes that lose the purple

The colour of ube comes from its anthocyanins, the same pigments found in red cabbage or blueberries. They are sensitive to two things. Excessive heat first: past a bare simmer, milk that boils properly turns the purple towards greyish brown within minutes. Low heat, always, and a hand whisk.

Then acidity, but the right way round: anthocyanins turn blue-grey in an alkaline environment and stay a good purple in a neutral to slightly acidic one. In practice, never put bicarbonate of soda in this recipe, and be wary of certain fortified plant milks whose pH is higher — if your drink starts looking grey, a few drops of lemon juice revive the shade without being noticeable in the taste.

One last point: the quality of the powder. A pale powder, cut with starch or mixed with taro, will give a washed-out purple whatever your technique. That is the whole issue explained on our page on recognising authentic ube powder.

Which powder should you choose for your hot chocolates?

For this recipe, the natural powder remains the default choice: it lets the white chocolate and the vanilla speak. If you drink hot ube drinks regularly, the flavoured powders let you vary things without changing the method at all — the vanilla flavour for an even milder version, the hazelnut flavour for a praline profile reminiscent of end-of-year hot chocolates.

As for size, the 200 g at 16.90 € covers around 50 drinks: it is the best quantity-to-price ratio for regular use. To try it out first, the 100 g at 12.90 € is enough. And if you are torn between natural and flavoured, the Duo Rituel at 29.90 € pairs the 200 g natural with a 100 g flavour of your choice. All the sizes and criteria are detailed in our guide to buying ube powder.

Making it ahead and storing it

Ube hot chocolate scales up very well. Multiply the proportions by three, let it cool and keep it in the fridge in a sealed jar: it will last 3 days. It will thicken noticeably in the cold, which is normal — the starch sets. Reheat over low heat while whisking, adding a splash of milk to get back to the right consistency. Avoid the microwave at full power, which overheats in spots and dulls the colour.

You can also make up a dry mix in advance: 6 teaspoons of ube powder, 160 g of grated white chocolate, a pinch of salt, all in a jar. All that is left to do is take out half of it and follow the recipe. It makes a lovely edible gift, provided you keep the jar away from the light — our benchmarks are gathered on the page about storing ube powder.

Frequently asked questions

Can you use milk chocolate? Yes, reducing it to 60 g and leaving out the sugar. The colour will be a duller purple, more mauve than deep violet.

The drink is too thick, what should I do? Loosen it with hot milk, 50 ml at a time. A drink that is too thick usually means it was heated too long after the ube went in: 2 to 3 minutes is enough.

The ube flavour is too faint. Go up to 4 teaspoons for 500 ml, but no further: the tuber note becomes earthy and throws the drink off balance.

Can it be made in a milk frother? Yes, provided you first make the ube paste with cold milk and choose a hot chocolate programme rather than a milk foam one.

You now have everything you need for a purple hot chocolate that is anything but a gimmick: a creamy base, a natural colour that holds, and four variations so you never tire of it. Order your 200 g ube powder and find all our ideas in the guide to our ube recipes.
