$3.99 to $4.89 by size, matching the other two Fusions, with no calorie figure published.
Wendy's OREO Brownie Vanilla Frosty Fusion price is $3.99 at the entry size and $4.89 at the top of the published band. Cookie dough and caramel crunch start at exactly the same $3.99, so nothing on price separates the three. OREO is the only outside brand named anywhere in this section. No calorie count is published for the cup, and the macro panel could not be read.

If something goes wrong
The OREO Fusion costs more than the other two Fusions in store
- Cause
- All three start at $3.99 nationally, and each is sold across a band to $4.89. Cup size and the franchisee's own board account for any local gap.
- Fix
- Compare like sizes at one restaurant. Nothing recorded in August 2026 priced this flavour above its two tier-mates.
The row shows a price but no range
- Cause
- One reading stands behind it, taken from Wendy's own site. A range needs at least two points, and inventing a second one would be worse than leaving the cell empty.
- Fix
- Use $3.99 as the national entry price and check the app for the branch figure.
Allergen information for the OREO pieces cannot be found here
- Cause
- Every allergen panel on the Wendy's ordering site loads through a browser script, and each read returned a placeholder, so no allergen data could be read for any product in this section.
- Fix
- Ask at the counter or read the panel in the app, which renders the script properly. Nothing on this page substitutes for it.
The one flavour named after somebody else's biscuit
Eight of the nine rows in this section describe themselves in generic words: chocolate, vanilla, cookie dough, caramel crunch, brownie batter, strawberry, apple crumble. This row names a brand. OREO is the only third-party trademark on the Frosty board, and a licensed ingredient is a large part of what the Fusion tier is selling.
What's in it
A vanilla Frosty with OREO pieces and brownie folded through it, priced from $3.99 and running to $4.89 across the cup sizes on Wendy's own ordering site. Portion sizes for the mix-in are not published. Calories are not published either, because Frosty products on the site carry a size span rather than a figure for one cup, and everything below the calorie line, including the allergen list that a biscuit-based mix-in makes people want, could not be read from the page at all.
The licence does buy the shopper one thing worth having. A named biscuit is a known quantity in a way that a phrase like caramel crunch is not, which matters when nothing else about the mix-in is documented.
Is it worth it
On price, the tier decides, not the flavour. Three Fusions all start at $3.99, so anyone choosing between OREO brownie, cookie dough and caramel crunch is choosing on taste with no money in it.
On value against the rest of the section, the picture is harder. A plain vanilla cup starts at $1.39, which puts $2.60 on the mix-in. Brownie Batter Vanilla Frosty Swirl carries much the same idea at $2.99, a dollar below this row, and no published figure explains what the extra dollar delivers in either portion or size.
One more comparison is worth making before ordering. Apple Crumble Frosty Fusion, Vanilla, the dearest row in the section, asks $4.19 against this row's $3.99, so twenty cents separates the top of the board from the middle of it. Anyone treating four dollars as the ceiling for a dessert has three Fusions and one apple crumble inside that budget.
For a cup that costs four dollars, the amount of information Wendy's publishes about it is thin. Price is solid and first-party. Everything else is a blank. That is the honest state of this row, and the app with a restaurant selected remains the only route to a figure that will match the till, since prices here are franchise-set.

Questions people ask
How much is an OREO Brownie Frosty Fusion?
From $3.99, on a Wendy's band reaching $4.89 across the cup sizes. That matches the cookie dough and caramel crunch Fusions to the cent.
How many calories are in the OREO Brownie Frosty Fusion?
No figure is published. Frosty rows on the Wendy's site show a size span instead of a per-cup count, and the fat, sugar and protein panel could not be read.
Is there an allergen list for this Frosty?
Not one that could be read. Allergen panels on the Wendy's ordering site load through a script, and every attempt returned a placeholder, so the field was left empty rather than guessed.
Is this page an official Wendy's price list?
No. The $3.99 figure is Wendy's own entry price, posted on the company's own ordering site in August 2026 and dated under the table rather than presented as a live quote.
Can this site tell me the price at my local Wendy's?
No. The operator prices each board, so the same cup can differ between two restaurants a few miles apart. The Wendy's app settles it for one address.
