About the Mini Smarties Fusion

The Burger King Mini Smarties Fusion has no price published by Burger King in its restaurant data and carries 152 kcal. Our Smarties Fusion, only smaller. It sits in the desserts section of the UK menu, alongside 19 other items.

The breakdown reads 5.2g of fat, 3.6g of it saturated, 0.12g of salt, 2 percent of the 6g daily maximum, 19g of sugar.

At 92g the Mini Smarties Fusion works out at roughly 165 kcal per 100g. That makes it less concentrated than it looks, so it reads as a side rather than a meal.

Sugar accounts for roughly 50 percent of the calories here, which is 21 percent of the 90g daily reference. The energy figure alone hides that, which is why the 19g matters more here than the 152 kcal does.

On calories it lands 123 kcal below the desserts average of 275 kcal. Cheddar Cheese Sauce XL sits at 155 kcal, near enough identical, so the two are interchangeable on the numbers even though they are nothing alike to eat.

On the recipe itself Burger King declares nothing, but it flags gluten, wheat, milk as possible by cross contact, 3 entries in total. For a preference the first list is the one to read. For a genuine allergy it is the second, every time. Of the 18 items in this section with an allergen declaration, 4 flag fewer than this one. The declaration is the brand's, made against the fourteen allergens UK law names, and it stops at the recipe. The branch is the part you have to ask about.

If you are building a full order, Small Ben & Jerry's Caramel Chew Chew at £2.29 and Large Ben & Jerry's Cookie Dough at £5.99 sit in the same section and are the obvious companions. The calculator adds the calories as you build the order, and the price list covers everything not named here.

How to Make a Mini Smarties Fusion at Home

A sundae is soft serve plus a sauce, so the only thing worth getting right is the ice cream itself. This makes a Smarties version close to the counter one without a machine.

Tips

  • Chill the bowl and the whisk first. Warm equipment stops cream whipping properly.
  • Do not stir once it is in the freezer. Left alone it stays smoother than anything you keep breaking up.
  • Burger King's own portion is 92g at 152 kcal, so weigh the first one and you will know what you are working to.

Variations

  • Layer the sauce through the middle rather than over the top for a rippled version.
  • Add crushed biscuit at the base for texture against the soft serve.
  • Use oat cream and condensed oat milk for a dairy free version.

Serve it last and serve it alone. Next to anything else on this menu it stops registering as a dessert.

Mini Smarties Fusion Questions

Burger King has not published a confirmed restaurant price for the Mini Smarties Fusion in the price data this site draws on, so no figure is shown rather than a guess. Calories and full nutrition for it are listed above, and the desserts menu shows prices for everything else in the section.

The Mini Smarties Fusion contains 152 kcal, which is 8 percent of a 2,000 kcal day. That is the item alone. Fries and a full sugar drink can add as much again, which the calorie calculator makes obvious.

It carries 0.12g of salt. UK guidance sets the adult limit at 6g a day, so this is 2 percent of the daily maximum from one item. Fries and a dip on the side will push the figure up again before the meal is finished.

It is most often ordered as part of a meal rather than on its own. From the same section, Mango and Passionfruit Cheesecake Bar and Gooey Salted Caramel Cheesecake Bar are worth a look. The sides page covers what each addition costs and adds.

Not necessarily. Individual restaurants drop items when they sell out, and promotional items disappear once the run ends. The Burger King app shows the live menu once you select a restaurant, which is the only reliable way to check before travelling. The store locator lists every UK branch.
