Updated 12 September 2026 · price from a third party listing
Millionaire's Shortbread (Gluten Free) sits 32nd of 98 on price in Costa Coffee’s Our menu section, at £3.50 and 279 kcal. Updated 12 September 2026.
A gluten free biscuit topped with lightly salted caramel, milk chocolate, and drizzled with white chocolate.
The £3.50 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 Millionaire's Shortbread (Gluten Free)
How to order Millionaire's Shortbread (Gluten Free) at Costa Coffee
You can order Millionaire's Shortbread (Gluten Free) at the counter, at a Costa Coffee kiosk, or in the Costa Coffee app for collection or delivery. It is filed under Our menu. Not every branch stocks it, and the app is honest about that before you pay.
Costa Coffee Millionaire's Shortbread (Gluten Free) price in 2026
The Costa Coffee Millionaire's Shortbread (Gluten Free) price in 2026 is £3.50 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 32nd of 98 on price. Expect more at airport, motorway and station branches than on a high street, and more again through a delivery app.
More protein for similar money
Free Range Egg Mayo Sandwich costs about the same at £3.69 and carries 15g of protein against this item's 1.5g. If the point of the order is to be full for longer, that is the better buy of the two.
Finding it near you
We list 2,561 Costa Coffee branches across 3 of the four UK nations, with the Birmingham postcode area holding the most at 72. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Costa Coffee app confirms it in seconds.
Diet marking
Costa Coffee marks this as vegetarian. That is the chain's own classification of the recipe rather than a statement about how it is cooked, and vegan marking in particular sits alongside shared equipment at most of these brands.
Allergens declared
Costa Coffee declares 2 of the 14 allergens UK law requires to be listed for this item: milk and soya. It also lists tree nuts 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.
Pro Tips for Ordering Millionaire's Shortbread (Gluten Free)
Sharing it is the realistic option
Dessert figures are for one portion as served, and most of these are built for one person to finish. One split across a table makes the numbers work without giving it up.
Where it sits on price
31 items cost less than this one in the Our menu section and 66 cost more, out of 98 we hold a price for. The closest thing to it on price is Raspberry & Almond Bake at £3.50, so those two are the real comparison when you are deciding.
Protein for the calories
It gives 0.5g 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 114th of 132 in its section.
