Get ready to ditch your usual Costco food court favorites because there’s a new dessert in town that’s causing a stir—and it’s a game-changer for anyone who loves a minty, chocolatey treat. Costco’s Double Chocolate Mint Sundae is here, and it’s like a Girl Scout Cookie Thin Mint came to life in sundae form. But here’s where it gets controversial: is it worth the extra 50 cents compared to their classic sundaes? Let’s dive in and find out.
Costco recently rolled out this limited-time treat at food courts nationwide, just in time for St. Patrick’s Day and Girl Scout Cookie season—talk about perfect timing! The sundae features mint soft serve, which has temporarily replaced the chocolate option in Costco’s two-flavor machines. That means no mint-chocolate swirl, but you can still get a mint-vanilla swirl if you’re not fully committed to the minty experience. The real star here is the layering of chocolate sauce and crunchy, chocolatey cookie crumbles, giving it that ‘double chocolate’ title. At $2.99, it’s a bit pricier than the always-available chocolate and strawberry sundaes, but is it worth the splurge? That’s the question.
And this is the part most people miss: the cookie crumbles aren’t your typical Oreos. They’re crunchier and more chocolate-forward, reminiscent of a Thin Mint without the outer shell. Costco doesn’t hold back on these crumbles either—you’ll find a generous layer at the bottom and on top of the sundae. However, the chocolate sauce situation is a bit hit-or-miss. While some sundaes come loaded with it, others (like mine) could use a bit more, especially in the middle where the mint ice cream dominates. It’s a small gripe, but one that could make or break the experience for chocolate lovers.
The mint flavor itself is bold—think Shamrock Shake intensity rather than the subtlety of a Thin Mint cookie. But honestly, that works in its favor. With a larger portion than a few cookies, the strong mint flavor keeps things interesting without becoming overwhelming. Plus, the sundae isn’t overly sweet, making it easy (and dangerously satisfying) to polish off the entire cup. My partner and I devoured ours and are already planning our next Costco trip for round two.
But here’s the controversial question: does Costco’s sundae outshine other mint-chocolate fast-food desserts? Let’s compare. McDonald’s Shamrock Shake, a classic since 1967, offers a milder mint-vanilla blend that even mint skeptics can enjoy. Wendy’s Girl Scout Thin Mints Frosty combines minty cookie crumble sauce with your choice of chocolate or vanilla Frosty. And Dairy Queen’s Mint Oreo Blizzard? It’s a mint chocolate lover’s dream with Oreo pieces and mint sauce in vanilla soft serve. Each has its own charm, but Costco’s sundae stands out for its unique cookie crumbles and generous portion size.
So, have you tried Costco’s Double Chocolate Mint Sundae? Is it worth the hype—and the extra 50 cents? Or do you prefer sticking to the classics? Let us know in the comments. And if you haven’t tried it yet, hurry—this limited-time treat won’t last forever. But here’s the real question: is it the ultimate mint chocolate dessert, or just another seasonal fad?
