A New Frozen Treat at Costco Packs Two Dessert Favorites Into One Dreamy Bite
If summer desserts are becoming the main event at your house, Costco just added a new freezer find that fits right in with warm nights outside, kids' birthday parties, backyard hangouts, and all those little moments that call for something sweet and easy to grab.
The newest frozen dessert was spotted this week in stores and delivers a dreamy combo in a smaller, shareable size. And judging by early reactions, there are plenty of reasons to get excited about this one.
You can see the frozen treat up close in this May 14 TikTok from @costcochikafinds:

Costco's New Brookie Dough Ice Cream Sandwiches Pack Brownie and Cookie Flavors Into a Perfect Summer Dessert
Costco's new Brookie Dough Ice Cream Sandwiches in Chomp size from Nightingale Ice Cream Sandwiches feature a chewy brownie on one side, a soft chocolate chip cookie on the other, and creamy chocolate chip cookie crumb ice cream in the middle.
The flavor combo hits that perfect sweet spot, and the smaller cube shape makes them much more convenient than full-size sandwiches. They're ideal for sharing during movie nights, pool days, or casual get-togethers when you want something sweet without having to pull out larger desserts or deal with messy scooping.

Beyond the fun mashup, Nightingale has built a loyal following for its premium ingredients and creative flavors. The woman veteran-owned company uses non-GMO sourced ingredients and makes everything in a certified nut-free facility.
Fans on the company's website are already singing the praises of this flavor mashup.
One reviewer called them "The best ice cream sandwiches ever!"
Another wrote, "We're talking delicious. Perfect treat. Well played, Nightingale."
Someone else added, "Love it! One of the best and I'm a Nightingale lifer!"
Availability can vary by club, so if you don't see them in your store just yet, they may still be rolling out. But if you spot them, they're worth grabbing, especially as the weather warms up and everyone's looking for something cool and easy to share.
