I tried every kind of McFlurry at McDonald's and ranked them from worst to best

Each mini-sized, 4-ounce McFlurry cost $2.99, excluding tax, at my local McDonald’s in Brooklyn, New York. A McFlurry is also available in a regular 12-ounce size for $5.39, excluding tax.

Based on weight, it’s more cost-effective to order the regular-sized McFlurry, but for the sake of trying each flavor, I ordered the smaller size.

It came topped with a rainbow of M&M’s that, after sitting in the ice cream for a few minutes on my walk home, had partially melted and created a swirl of color in the vanilla ice cream.

I wanted more notes of chocolate, and overall, didn’t find this McFlurry to be the most flavorful of the bunch.

The vanilla soft-serve ice cream was creamy and sweet, but I simply preferred the toppings on the other two sundaes.

It’s made with vanilla soft-serve ice cream, Hershey’s milk chocolate, graham cracker pieces, and mini marshmallows. As a limited-time offer, it’s only available at McDonald’s through August 11.

Of the three McFlurries I tried, this one packed the most flavor and variety. The graham crackers added a satisfying crunch and a molasses-like sweetness, the chocolate was rich, and the marshmallows brought that classic s’mores taste that reminded me of camping in the summer as a kid.

But all the toppings were concentrated on the top, so once I got through that layer, I was left with plain vanilla ice cream, which made the overall experience feel a bit underwhelming.

Oreo was the first flavor introduced in the McFlurry menu, and it’s a classic for a reason.

It’s made with a base of vanilla soft-serve ice cream mixed with Oreo cookie pieces, which is then topped with additional Oreo pieces.

The soft-serve ice cream was exceptionally creamy and blended well with the pieces of crushed Oreos.

I got a strong chocolatey flavor throughout the ice cream, unlike the other two sundaes, where the toppings were mostly concentrated on top.

From the flavor to the low cost — just under $3 — I could see myself adding an Oreo McFlurry to my next McDonald’s order as an affordable sweet treat.

While both the other flavors were tasty in their own right, the Oreo version simply packed the most flavor.
