I Tried Costco’s New Double Chocolate Mint Ice Cream Sundae, And It’s 100% Worth The Hype
If you’re the kind of person who never skips the Costco food court, it’s time to pay attention. Without any flashy announcement or countdown, Costco has quietly rolled out a brand-new dessert—and fans are already obsessed. Meet the Double Chocolate Mint Sundae, a minty, chocolatey treat that’s giving serious Thin Mints energy.
Let’s break down why this sundae is quickly becoming the internet’s favorite Costco find.
What Is Costco’s Double Chocolate Mint Sundae?
The uble Chocolate Mint Sundae is a limited-time food court item that’s currently appearing at Costco locations across the U.S. While not every warehouse has it just yet, reports suggest it’s rolling out fast.
Here’s what you get for $2.99:
- A generous base of mint ice cream
- A rich chocolate sauce drizzle
- A topping of cookie crumbles with chocolate bits
Yes, it’s the most expensive sundae on Costco’s menu—but it’s only 50 cents more than the regular version, and still a steal by food court standards.
Why Everyone’s Calling It “Girl Scout Cookie Coded”
If you love Thin Mints, this sundae feels like it was made for you. The mint-and-chocolate combo is unmistakable, and fans are already drawing comparisons to the iconic cookie from Girl Scouts of the USA.
Popular Instagram account @costconewdeals—a trusted source for Costco menu drops—gave the sundae a 10/10, and food influencer Morgan Chomps praised how well the mint and chocolate balance, calling it “a solid offering for March.”
Early reviews suggest this isn’t just a novelty item—it’s a potential seasonal favorite.
Mint-Chocolate Mania Is Everywhere Right Now
Costco isn’t alone in leaning into the mint-chocolate trend. Over at Wendy’s, the Thin Mints Frosty has made a comeback, blending the beloved cookie flavor with creamy soft-serve.
Meanwhile, Miss Jones Baking Co. has partnered with the Girl Scouts to release Girl Scout Cookie–inspired baking mixes, including—you guessed it—Thin Mints.

And of course, it wouldn’t be late winter without the annual return of the Shamrock Shake vibes. Mint and chocolate are clearly having a moment, and Costco’s sundae fits right in.
Should You Try It?
Absolutely. If you’re already doing a big Costco shopping run, this sundae is the perfect sweet reward before you head home. It’s indulgent without being overwhelming, nostalgic without feeling gimmicky, and priced just right.
If the early buzz is any indication, the Double Chocolate Mint Sundae may stick around for a few months—but as with all Costco food court favorites, there are no guarantees. So if you spot it on the menu, don’t overthink it. Grab one.
