Everything You Need to Know About Burger King King Fusion - Smarties
How to order King Fusion - Smarties at Burger King
Counter, kiosk and app all carry it. The Burger King app adds collection and delivery. It is filed under Desserts. Availability is set per branch, so a smaller site may not carry it at all.
Burger King King Fusion - Smarties price in 2026
There is no verified Burger King King Fusion - Smarties price for 2026. Burger King prices per branch and publishes no national list for it, so the accurate figure is the one your own branch shows in 2026. Any site quoting a single exact national price for this item is guessing, and we would rather show the gap.
Sugar in plain terms
25g of sugar works out at roughly 6 teaspoons. The adult reference intake is 90g a day and the NHS free sugars guideline is tighter at 30g, so one of these covers a real portion of either figure.
What 199 kcal means here
199 kcal is well below the Desserts average. On its own it is a small addition to a day rather than a meal. 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.
Finding it near you
We list 584 Burger King branches across 4 of the four UK nations, with the Northern Ireland postcode area holding the most at 25. Menus vary by site, so a listing here is national rather than a promise about your nearest one. The Burger King app confirms it in seconds.
Allergens declared
Burger King declares 2 of the 14 allergens UK law requires to be listed for this item: cereals containing gluten and milk. 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 King Fusion - Smarties
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 Burger King rather than an awkward one.
Protein for the calories
It gives 2.0g of protein per 100 kcal, against a menu average of 3.7g across everything we hold for Burger King. 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 7th of 15 in its section.
