Costco Debuts A New Double Chocolate Mint Sundae

Costco just quietly dropped a new mint chocolate dessert at its food court, and regulars are already treating it like a seasonal side quest.

Say hello to the Double Chocolate Mint Sundae. It’s mint soft serve layered with chocolate cookie crumbles and chocolate sauce, gently swirled into a mint-green-and-brown tie-dye situation that looks way more dramatic than its $2.99 price tag suggests.

Some locations reportedly soft-launched it with free samples (elite Costco behavior), and early reactions online say the combo actually works. The mint stays mellow, the cookie pieces add texture, and the chocolate keeps things grounded. If mint chocolate is your top choice, this one feels aimed directly at you.

Chocolate not your thing? Apparently you can also order the mint soft serve on its own.

The sundae started rolling out in February and is slowly making its way across stores nationwide. There’s no official end date yet, but it’s currently replacing Costco’s Caramel Brownie Sundae, which means this is very much a limited time moment.

Worth noting: this thing clocks in at 790 calories. But let’s be honest, if you’re already walking into Costco for bulk groceries and impulse purchases, what’s one mint chocolate sundae on the way out?

At $2.99, it’s an easy yes.
