Starbucks Pain au Chocolat contains 297 kcal per pastry — 15% of the adult 2,000 kcal daily reference intake, 19% for a child aged 7 to 10, and 23% for a child aged 4 to 6. It is the second lowest calorie sweet pastry at Starbucks after the Butter Croissant at 259 kcal and the All Butter Croissant at 287 kcal, sitting below the Pain au Raisin at 319 kcal. The laminated butter pastry with a dark chocolate filling delivers a moderate calorie count relative to filled or iced pastries.

Per pastry: 297 kcal, 16g fat (9.5g saturated), 33g carbohydrate (11g sugar), 5.4g protein, 0.45g salt. The saturated fat at 9.5g is 48% of the adult daily guideline of 20g. The sugar at 11g is 37% of the adult daily free sugar limit of 30g. The salt at 0.45g is 8% of the adult daily limit of 6g.

Starbucks Pain au Chocolat contains 11g of sugar per pastry — 2.8 teaspoons and 37% of the adult daily free sugar limit of 30g. For a child aged 4 to 6, this uses 58% of their daily free sugar limit. At 11g it is one of the lowest sugar pastry options at Starbucks — below the Pain au Raisin at 17g, the Danish Apple and Cinnamon Swirl at 21g and well below the Cinnamon Bun at 28g. The sugar comes from the small amount of sugar in the laminated pastry dough and the dark chocolate filling — dark chocolate contains less sugar than milk or white chocolate, which keeps the total lower than chocolate-containing pastries using sweeter chocolate variants. The NHS free sugar limit is 30g per day for adults, 24g for children aged 7 to 10, and 19g for children aged 4 to 6.

Starbucks Pain au Chocolat contains 0.45g of salt per pastry — 8% of the adult daily limit of 6g and 15% of the daily limit for a child aged 4 to 6. The salt comes from the salted butter laminated into the dough and from the salt used in the pastry dough to control yeast activity. It is low in salt and not a significant nutritional consideration relative to the saturated fat content.

Starbucks Pain au Chocolat contains 9.5g of saturated fat per pastry — 48% of the adult daily guideline of 20g and 59% for a child aged 4 to 6. The saturated fat comes from the butter laminated repeatedly into the pastry dough — the same technique as croissant production — and from the cocoa butter in the dark chocolate filling. Despite dark chocolate being lower in sugar than milk or white chocolate, it still contains significant cocoa butter which is a saturated fat source. At 9.5g the Pain au Chocolat is slightly higher in saturated fat than the Butter Croissant at 9g but lower than the Almond Croissant at 12g.

Starbucks Pain au Chocolat contains 5.4g of protein per pastry — 11% of the adult daily reference intake of 50g. The protein comes from the flour and eggs in the laminated pastry dough. The dark chocolate filling contributes a small amount of protein from the cocoa solids. At 5.4g for 297 kcal the protein-to-calorie ratio is low and typical of butter-rich laminated pastry products.

Yes. NOVA 4, ultra-processed. The dark chocolate filling contains soya lecithin as an emulsifier — the primary reason soya appears as a declared allergen. The laminated pastry dough contains emulsifiers and dough conditioners to improve shelf life. These industrial additives determine the NOVA 4 classification despite the core recipe using familiar pastry-making ingredients.

Starbucks Pain au Chocolat contains wheat/gluten, milk, egg and soya as declared allergens — four allergens. The wheat comes from the flour in the pastry dough. The milk comes from the butter in the laminated dough. The egg comes from the eggs in the dough and the egg wash on the exterior. The soya comes from the soya lecithin used as an emulsifier in the dark chocolate filling. It does not contain peanuts, tree nuts, fish, shellfish, celery, mustard, sesame, lupin or molluscs. Always tell your barista if you have a severe allergy before ordering.

Yes. Starbucks Pain au Chocolat is suitable for vegetarians. It contains no meat or fish. It is not suitable for vegans as it contains butter, eggs and milk in the pastry. It is also not suitable for those with wheat, milk, egg or soya allergies. With no tree nut allergen it is more accessible than the Almond Croissant on allergen grounds.

At 11g of sugar — 58% of the daily free sugar limit for a child aged 4 to 6 — the Pain au Chocolat is one of the more moderate sweet pastries for children on sugar grounds. The 9.5g saturated fat uses 59% of their daily guideline, which is the primary nutritional concern for younger children. Four allergens are declared including soya. It is one of the lower sugar sweet pastry options at Starbucks and more appropriate than the Cinnamon Bun, Danish Apple Swirl or Almond Croissant for a child watching sugar intake — though the saturated fat from the butter pastry remains a consideration.

The dark chocolate filling in the Pain au Chocolat contributes less sugar than milk or white chocolate would in an equivalent item. Dark chocolate is made primarily from cocoa solids and cocoa butter with a relatively modest sugar content — a typical 70% dark chocolate contains around 30g of sugar per 100g. Milk chocolate contains approximately 55g of sugar per 100g, and white chocolate up to 60g. In the Pain au Chocolat, the two sticks of dark chocolate filling add sugar at the lower end of the chocolate spectrum, keeping the total pastry sugar at 11g versus what a milk chocolate filling would produce. This is why the Pain au Chocolat is one of the lower sugar pastries in the Starbucks range despite containing chocolate.

At 11g of sugar the Pain au Chocolat leaves significant room for a drink. A plain Cappuccino or Flat White adds 9-12g from milk, bringing the total to 20-23g — comfortably within the adult daily free sugar limit of 30g. A Caramel Macchiato adds 23g, bringing the total to 34g — just over the adult daily limit. An unsweetened Americano or herbal tea at zero sugar keeps the combined total at 11g — one of the few sweet pastry and drink combinations at Starbucks that stays well within the adult daily limit. The Pain au Chocolat is one of the few sweet items where even a moderately sweetened drink keeps the total within range.

The Pain au Chocolat contains 297 kcal versus 259 kcal in the Butter Croissant — 38 more calories. Sugar is higher at 11g versus 5.4g — the dark chocolate adds approximately 5-6g of sugar. Saturated fat is higher at 9.5g versus 9g — minimal difference from the cocoa butter in the chocolate. The Pain au Chocolat adds soya as a fourth allergen versus three in the Butter Croissant — from the soya lecithin in the chocolate. For the lowest calorie and lowest sugar pastry the Butter Croissant is better. For those who want a chocolate element while keeping sugar relatively low, the Pain au Chocolat is a reasonable choice — at 11g sugar it is still one of the lowest sugar pastries at Starbucks.

Starbucks Pain au Chocolat is one of the lower calorie and lower sugar sweet pastry options at Starbucks at 297 kcal and 11g sugar. The dark chocolate filling keeps the sugar lower than most sweet pastries because dark chocolate is lower in sugar than milk or white chocolate. Four declared allergens — wheat, milk, egg and soya — with no tree nuts. It is suitable for vegetarians but not vegans. For those wanting a chocolate-containing sweet pastry at Starbucks on moderate nutritional grounds, the Pain au Chocolat is the most appropriate choice — lower in both calories and sugar than the Chocolate Twist, Blueberry Crumble Croissant Bun and Cinnamon Bun. The 9.5g saturated fat from the butter pastry is the primary nutritional consideration.
