Cinnamon Bun sits 39th of 98 on price in Costa Coffee’s Our menu section, at £3.75 and 447 kcal. Updated 12 September 2026.
A bun swirled with cinnamon filling, decorated with cream cheese icing and dusted with cinnamon powder.
The £3.75 figure came from a third party listing rather than from Costa Coffee, which means it may reflect a delivery menu. Delivery prices sit above in restaurant prices before any fee is added, so treat this as the ceiling rather than the till price.

Everything You Need to Know About Costa Coffee Cinnamon Bun
How to order Cinnamon Bun at Costa Coffee
Cinnamon Bun is available at the till, on the kiosk screens and through the Costa Coffee app, for collection or for delivery. It is filed under Our menu. Branch by branch availability varies, which the app reflects once you choose a location.
Costa Coffee Cinnamon Bun price in 2026
The Costa Coffee Cinnamon Bun price in 2026 is £3.75 on the figures we hold. The figure came from a third party listing rather than from Costa Coffee, so read it as a ceiling. Within the Our menu section that puts it 39th of 98 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
Protein for the calories
It gives 1.6g of protein per 100 kcal, against a menu average of 3.4g across everything we hold for Costa Coffee. That is a weak ratio for this menu, which matters more than the raw protein figure when you are comparing two items of different sizes. On raw protein it ranks 61st of 132 in its section.
A lighter choice in the same section
Raspberry & Almond Bake sits in the same part of the menu at 346 kcal, which is 101 fewer than this for £3.50. That swap is the single biggest change available inside this section, and it needs no substitution or special request at the counter.
More protein for similar money
Tuna Melt Panini costs about the same at £4.30–£6.10 and carries 26g of protein against this item's 7.2g. If the point of the order is to be full for longer, that is the better buy of the two.
What 447 kcal means here
447 kcal is well above the Our menu average. That is a normal single course for most people, and it leaves room for a side. The 2,000 kcal figure printed on UK menus is a reference intake for an average adult, not a target, and it is the number these percentages are worked against.
Pro Tips for Ordering Cinnamon Bun
Ordering it
The figure in the table is the standard build. Anything added at the counter sits on top of it, and anything left out comes off, which is a normal request at Costa Coffee rather than an awkward one.
Where it sits on price
38 items cost less than this one in the Our menu section and 59 cost more, out of 98 we hold a price for. The closest thing to it on price is Pure Chamomile Infusion at £3.70, so those two are the real comparison when you are deciding.
Allergens declared
Costa Coffee declares 3 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten, eggs and milk. It also lists soya as a possible trace, meaning Costa Coffee cannot rule that out. A declaration covers the recipe and not the kitchen, and every one of these chains prepares food in shared fryers and on shared surfaces. For a severe allergy the only reliable check is asking staff on the day.
