A successful cupcake is two successes stacked on top of each other: a light crumb that stays moist for two days, and a frosting firm enough to hold a rosette without being sickly. Add a deep purple obtained without a single drop of colouring, and you have the dessert that silences a birthday table. Ube cupcakes are exactly that: a supple vanilla base tinted by the purple yam of the Philippines, topped with a cream cheese frosting that is also purple, one shade lighter than the crumb.
The difficulty is not in the technique — a mixer, two bowls, a piping bag — but in two adjustments almost nobody explains: rehydrating the powder before folding it in, and the acid balance of the frosting, which decides the final shade of purple. This page gives the recipe to the gram, the step-by-step of the piping, the mistakes that make the domes sink, and the variations that genuinely work.
The ingredient behind this recipe: Ube Powder Nature 200 g — 16.90 €. 100% purple yam of the Kinampay variety, grown in the Visayas, no additives, no colouring and no added sugar, packed in Aix-en-Provence. One bag covers around five batches of cupcakes, frosting included.
Cupcake or muffin: these are not the same batter
The confusion is common and it has practical consequences. The muffin relies on the all-in-one method: you pour the liquids over the dry ingredients and mix for thirty seconds, lumps tolerated. The result: a dense crumb, a rounded, cracked dome, and a cake you eat plain. Our ube muffins follow that logic.
The cupcake, on the other hand, is a miniature cake. You cream the butter with the sugar to work in air, add the eggs one by one, and end up with a fine, tight and far lighter crumb. Above all, the top has to stay flat: that is the landing surface for the frosting. A cupcake that domes is a failed cupcake, whereas a muffin that does not dome is a failed muffin. Same purple ingredient, two opposite batters.
The practical consequence: do not look here for the thermal shock at 200 °C. Baking is done at a constant, moderate temperature, which also protects the anthocyanins responsible for the natural purple of ube.
The ingredients
For 12 cupcakes
- 25 g Ubedia Nature ube powder (2 generous tablespoons)
- 75 ml hot whole milk (around 80 °C, never boiling) for rehydrating
- 180 g low-protein plain flour — finer than a standard flour, it gives a tighter crumb
- 30 g cornflour — the secret to an airy crumb
- 8 g baking powder
- 2 g bicarbonate of soda
- 1 pinch of fine salt
- 140 g softened unsalted butter (creamy texture, not melted)
- 150 g caster sugar
- 3 medium eggs at room temperature
- 1 teaspoon vanilla extract
- 80 g crème fraîche or Greek yoghurt
For the ube cream cheese frosting
- 12 g ube powder
- 35 ml hot whipping cream
- 250 g cream cheese, very cold
- 110 g softened unsalted butter
- 180 g sifted icing sugar
- 1 pinch of salt and ½ teaspoon vanilla
Two technical details deserve an explanation. The cornflour replaces part of the flour and lowers the protein content: less gluten, therefore a more tender crumb, which is essential for a cupcake. And the bicarbonate of soda is not there to make it rise — the baking powder handles that — but to bring the pH back towards neutral. Ube pigments are sensitive to acidity: in an acid medium, the purple slides towards pink-magenta; brought back to neutral, it stays a deep mauve. That is precisely why the frosting, rich in acidic cream cheese, naturally comes out a shade lighter than the crumb — a gradient better embraced than fought.

The recipe, step by step
- Rehydrate the ube powder (5 min + 10 min resting). Tip the 25 g of powder into a bowl and add the 75 ml of hot milk in three goes, whisking briskly between each addition. You will get a smooth, glossy, grain-free paste. Leave it to swell for 10 minutes, then to cool to lukewarm. This step is not optional: it is what releases the colour and the aroma.
- Preheat the oven to 165 °C fan and line a 12-hole tray with paper cases.
- Sift the dry ingredients. Flour, cornflour, baking powder, bicarbonate and salt into a bowl. Sifting matters more here than in a muffin: the tight crumb of a cupcake shows up the slightest lump.
- Cream the butter and sugar (4 minutes). On a mixer at medium speed, until you have a pale, foamy mixture that has clearly grown in volume. This is where the lightness of the cupcake is created; do not cut it short.
- Add the eggs one by one, beating for 30 seconds after each addition. If the mixture splits, add a tablespoon of flour taken from the total.
- Add the lukewarm ube paste and the vanilla, then beat for 30 seconds. The whole thing turns purple immediately.
- Alternate dry ingredients and crème fraîche. A third of the dry ingredients with a spatula, half the crème fraîche, a third of the dry ingredients, the rest of the crème fraîche, then the final third. Stop as soon as the batter is even.
- Fill the cases two-thirds full — no more — using an ice cream scoop for perfect consistency. Tap the tray twice on the worktop to knock out the large bubbles.
- Bake for 18 to 20 minutes at 165 °C, without opening the door for the first 15 minutes. The top should stay almost flat and spring back under your finger; the tip of a knife comes out dry.
- Turn out after 5 minutes and leave to cool completely on a rack, an hour minimum. A warm cupcake melts the frosting, without exception.
The ube cream cheese frosting
The frosting is made while the cupcakes cool, never before.
- Mix the 12 g of ube powder into the 35 ml of hot cream, in three goes, until you have a smooth paste. Let it cool completely — a lukewarm base would melt the butter.
- Beat the softened butter on its own for 3 minutes until pale.
- Add the sifted icing sugar in two goes, on low speed first, then 2 minutes at medium speed.
- Fold in the cooled purple base, the vanilla and the salt.
- Finally add the very cold cream cheese all at once and beat for 30 seconds maximum. This is the critical point: beyond that, the cheese liquefies and the frosting no longer holds.
- If the texture lacks firmness, 20 minutes in the fridge is enough to rescue it.
For the pure butter version, more stable in warm weather and better suited to masking a layer cake, see our dedicated page on ube frosting (ube buttercream).
Piping
A 1M star nozzle for the classic rosette: start from the centre, turn outwards in a spiral, then come back up to the centre releasing the pressure. A 12 mm plain nozzle for a more contemporary look: three stacked rings of decreasing diameter. Either way, fill the bag only two-thirds full, and keep your hands cold — the heat of your fingers softens the frosting within minutes.
The 5 mistakes that ruin ube cupcakes
1. Adding the powder dry to the batter. Mistake number one, across every dessert. Without rehydrating, the powder stays as tiny grains, the colour peaks at a pale mauve and the crumb feels slightly gritty.
2. Rehydrating with boiling water. Above 85 °C, the pigments degrade and the purple turns brownish grey. Take the pan off before it boils.
3. Forgetting the compensating liquid. 25 g of ube powder absorbs the equivalent of 75 ml of liquid. Added to a standard cupcake recipe without that extra milk, the batter turns compact and the cake comes out dry. Our reference points recipe by recipe are gathered in the ube powder dosage guide.
4. Overbeating the cream cheese. Thirty seconds, not one more. A liquefied frosting cannot be rescued in the fridge: the cheese has released its water.
5. Frosting warm cupcakes. The butter in the frosting melts at 32 °C. Give it an hour to cool completely, and the piping stands up all evening.
Variations
Ube and coconut cupcakes
Replace the crème fraîche with 80 g of thick coconut milk and add 25 g of desiccated coconut to the batter. A veil of toasted coconut over the frosting finishes it off. This is the historic Filipino pairing.
Ube halaya centre
Once the cupcakes have cooled, hollow out a 2 cm well with an apple corer and fill it with a teaspoon of ube halaya, then pipe over the top. The effect on the first bite is worth the five minutes of work.
Vegan version
Baking-grade margarine instead of butter, plant-based cream cheese made from cashews (firmer than soya), 80 g of plant yoghurt, and the three eggs replaced with 180 g of unsweetened apple puree plus 1 teaspoon of cider vinegar. Ube powder is 100% plant-based by nature.
Gluten-free version
A gluten-free baking mix works in equal parts with the flour, keeping the cornflour. See our gluten-free ube powder page.
Mini cupcakes for a buffet
Same batter, mini cases, 11 to 12 minutes at 165 °C. Expect 30 pieces. This is the format that works best on a wedding buffet or a birthday table.
Keeping and transporting them
Unfrosted, the cupcakes keep for 3 days in an airtight box at room temperature and freeze for 2 months. Frosted, count on 48 hours in the fridge, in a tall box so the rosettes are not crushed — and take them out 30 minutes before serving, since cold frosting has no taste at all.
For transport, a compartmented carrier is essential: a cupcake lying on its side is a cupcake lost. As for the raw ingredient, our advice on storing ube powder explains how to preserve the colour and aroma of the bag once opened.
Which ube powder should you choose for cupcakes?
The fine, pale crumb of a cupcake, paired with a frosting that is almost white to begin with, immediately reveals the quality of the powder. Three criteria matter. The variety: Kinampay from the Visayas is reputed to be the most fragrant in the archipelago. Purity: a 100% ube powder, with no filler starch or added flavouring — a cut powder gives a greyish purple that shows up above all in the frosting. And the fineness of the grind, which determines how even the colour comes out.

Frequently asked questions
Why do my cupcakes dome instead of staying flat?
Oven too hot, cases filled too full, or too much raising agent. At 165 °C and filled two-thirds, the top stays flat. If a dome has formed anyway, level it off with a serrated knife: the cut will not show under the frosting.
How much ube powder for a clear purple?
25 g for 12 cupcakes gives a distinctly purple crumb and a definite taste. Go up to 35 g for a Filipino-bakery intensity, adding 25 ml of extra milk. For the frosting, 12 g is enough: beyond that, the texture turns grainy.
My frosting is leaning towards pink — why?
It is the acidity of the cream cheese shifting the shade of the pigments. A pinch of bicarbonate of soda (0.5 g maximum, no more) in the purple base of the frosting brings it back towards mauve. Many bakers prefer to keep that pink-purple contrast, which gives the rosette some depth.
Can the cupcakes be made the day before?
Yes, and it is even recommended: bake the cakes the day before, keep them unfrosted in an airtight box, and pipe on the day. The frosting can also be made 24 hr ahead, taken out 30 minutes before to soften it.
What is the difference with an ube layer cake?
The batter is similar, but the frosting proportions and the assembly method differ. Our ube cake recipe covers the large-format version.
