By Costco’s food court has always punched well above its weight — and the warehouse giant has done it again. The Costco Double Chocolate Mint Sundae is the new limited-time dessert taking social media by storm in February 2026, and TrendingUpdatesToday.com is breaking down everything shoppers need to know before heading to the food court.
What Is the Costco Double Chocolate Mint Sundae?
The Costco Double Chocolate Mint Sundae is a layered dessert featuring mint soft-serve ice cream, a generous pour of chocolate sauce, and chocolate cookie crumbles — stacked in a large cup and swirled into a visually striking mint-green and chocolate-brown combination. Think of it as a mint chocolate chip dream assembled with Costco’s signature value-first philosophy.
The sundae officially began rolling out at select Costco food court locations on February 16, 2026 — one day before McDonald’s re-launched its iconic Shamrock Shake — giving the warehouse club a surprisingly strategic head start in the seasonal green-dessert race.
How Much Does the Costco Double Chocolate Mint Sundae Cost?
At just $2.99, this is one of the most affordable Costco food court desserts you’ll find in 2026. That’s only $0.50 more than the classic chocolate or strawberry sundae, and significantly cheaper than a comparable McDonald’s Shamrock Shake, which runs around $5.19 for a medium. For shoppers looking for a Costco food court new item 2026 that delivers serious value, this checks every box.
Not a mint lover? You can also order the mint soft serve on its own for $1.99.
Costco Double Chocolate Mint Sundae vs. McDonald’s Shamrock Shake
Here’s how the two popular mint chocolate ice cream options stack up:
| Feature | Costco Double Chocolate Mint Sundae | McDonald’s Shamrock Shake (Medium) |
| Price | $2.99 | ~$5.19 |
| Calories | 790 | ~560 |
| Format | Sundae (layered) | Milkshake |
| Toppings | Chocolate sauce + cookie crumbles | Whipped cream |
| Availability | Costco members only | McDonald’s locations |
| Seasonal? | Yes (limited-time) | Yes (St. Patrick’s Day) |
While the Shamrock Shake is lighter in calories, the Costco limited-time sundae wins on price and overall portion size. Several food critics have noted the sundae’s cookie crumbles — denser than an Oreo, closer to a Girl Scout Thin Mint — give it a satisfying crunch the shake simply can’t match.
What Does It Taste Like? Early Reviews
Early reviews of the Costco food court dessert have been overwhelmingly positive. Food influencer @morganchomps confirmed it “doesn’t taste like toothpaste,” noting the mint flavor is present but balanced — more mint-chocolate-chip than peppermint candy. Instagram account @CostcoNewDeals called it “minty, chocolatey,” and praised the cookie crunch. The Daily Meal’s food court reviewer rated it above average for quality and unbeatable for value.
Some shoppers on Reddit report the mint flavor is on the subtle side, which may disappoint those hoping for an intense peppermint punch. However, most agree the layered combination of chocolate sauce, cookie crumbles, and creamy soft serve makes this one of the best Costco seasonal treats in recent memory.
Is the Costco Double Chocolate Mint Sundae Available Near You?
The Costco Double Chocolate Mint Sundae is currently rolling out nationally, with confirmed sightings in Los Angeles, Maryland, South Carolina, and the San Francisco Bay Area. However, not every Costco food court has it yet, so availability varies by location.
Since Costco now requires a membership card to order at the food court kiosk, you’ll need your membership card or app ready. As for how long it will last: no official end date has been announced, but given the Costco vs McDonald’s Shamrock Shake timing, most food industry watchers expect it to stay through St. Patrick’s Day on March 17, 2026.
It has replaced the Caramel Brownie Sundae for now, so fans of that item may need to wait for its return.
Is the Costco Double Chocolate Mint Sundae Worth It?
Absolutely — if you enjoy the mint and chocolate pairing. At $2.99 from the Costco food court, this limited-time sundae is exceptional value for a dessert of this size and quality. The 790-calorie count is substantial, making it a treat best shared or saved for a true indulgence moment. But as a seasonal, wallet-friendly food court splurge, it’s hard to argue against it.
