570 calories, and no recorded price: the M&M'S McFlurry is the heaviest dessert here.
No McDonald's MMs McFlurry price came out of this check. The cup McDonald's lists as the M&M'S McFlurry (Regular) returned no figure at any restaurant, so the row is blank rather than borrowed. What the company does publish is the calorie count: 570 for the regular size, the highest figure in Sweets & Treats and 160 calories above the OREO version of the identical format at the same cup size.

If something goes wrong
Both price cells on this row are empty
- Cause
- Every check run in August 2026 came back without a figure for this cup. An empty cell records that outcome instead of hiding it behind a sibling's number.
- Fix
- Take the OREO McFlurry row as the closest available guide, at $4.79 typical on a $3.99 to $5.59 band, then confirm the real number at the counter.
570 calories looks high for a dessert
- Cause
- It is the highest figure in this section, ahead of a small chocolate shake at 520 and well ahead of the OREO McFlurry at 410. Candy pieces carry more than cookie pieces.
- Fix
- Compare it against food rather than against other desserts. 570 sits within striking distance of a Big Mac at 580, which is the comparison most people find useful.
The calorie figure has been read only once
- Cause
- Two figures in this section were double-read under separate prompts, the OREO McFlurry at 410 and the Baked Apple Pie at 230. This one was not among them.
- Fix
- Treat 570 as McDonald's own number, because it is, while noting it has a single read behind it rather than two.
The heaviest cup on the dessert board, and the one nobody prices
This page exists to record an absence honestly. A price for this cup was looked for across every source used in August 2026 and none came back, which is unusual for an item that sits on the main menu of a national chain. The row therefore shows no typical price and no band, and the temptation to fill it with the OREO figure has been resisted, because the two are separate products that happen to share a machine.
What's in it
A regular cup with candy pieces spun through it, at the size McDonald's lists. The company publishes 570 calories for that cup. Everything below the calorie line could not be read, because the macro table and the allergen list are drawn into the product page by a calculator that runs in the browser, and a plain read of the page finds both of them empty.
Where 570 sits is the useful part. It is the highest calorie figure in Sweets & Treats. A small chocolate shake is 520. An OREO McFlurry, the same format at the same size with a different mix-in, is 410, so the choice of candy over cookie is worth 160 calories on its own. A Hot Fudge Sundae is 330 and a Vanilla Cone is 200, which means this cup carries nearly three times the calories of a plain cone. Outside the section, a Big Mac is 580, so the dessert lands within ten calories of the sandwich.
Is it worth it
On price nothing can be said, and that is the honest answer rather than a dodge. Without a single recorded figure there is no rate to calculate and no comparison to draw, so anyone weighing this against the OREO version is working from $4.79 and a shrug.
On calories the case is clear enough. Choosing this cup over the OREO version adds 160 calories, choosing it over a sundae adds 240, and choosing it over a cone adds 370. None of those numbers change with the restaurant, because they come from McDonald's rather than from a local board. Anyone tracking intake has a firmer basis for a decision here than anyone tracking spend does.
Why the price side is so thin comes down to structure. Around 95% of US restaurants under the brand are franchised, a share McDonald's states in its Form 10-K, and each operator prices the menu, so there is no national list to consult and no company figure to fall back on. Corporate publishes calorie counts across the menu and prices almost nowhere.
The practical route is short. Open the McDonald's app, set the restaurant, and read the cup's price there. That is the only figure that binds, and on this item it is the only figure that exists.

Questions people ask
How much is an M&M'S McFlurry?
No figure came back for it in this check, so no price is claimed. An OREO McFlurry, the same format at the same size, was recorded at $4.79 typical on a $3.99 to $5.59 band.
How many calories are in an M&M'S McFlurry?
570 for the regular cup, published by McDonald's. That is the highest figure in Sweets & Treats, ahead of a small chocolate shake at 520 and an OREO McFlurry at 410.
Which McFlurry has fewer calories?
The OREO version, by 160. Both are the same format at the same regular size, so the gap comes from what is spun through them.
Is this page an official McDonald's price list?
No. The only company figure on it is the 570-calorie count. Everything about price here records what independent checking found against published US prices in August 2026, which on this item was nothing.
Can this site tell me the price at my local McDonald's?
No page can, and this row shows the limit plainly. Franchisees run roughly 95% of US restaurants and set their own prices. The McDonald's app, with a restaurant selected, returns the figure that applies there.
