In many ways, s’mores are the perfect summer food—that nostalgic combo of chocolate and toasted marshmallow between graham crackers can instantly transport you back to the carefree days of childhood.

As fantastic as a fresh s’more is on its own, Costco’s latest dessert puts an oversized spin on the classic summer treat. And if members’ early reactions are any indication, shoppers won’t want to miss this eye-catching new bakery item while it’s available in stores.

This giant S’mores Bundt Cake is made for summer parties

As multiple shoppers have reported online, Costco has begun selling a new S’mores Bundt Cake by Jeans Posh Pantry. The 36-ounce dessert is large enough to feed a crowd and features layers of vanilla and chocolate cake topped with giant marshmallows, crumbled graham crackers, chocolate pieces, and a sweet chocolate drizzle.

Retailing for about $11.59 at most stores, the S’mores Bundt Cake puts a bakery-sized spin on everyone’s favorite fireside dessert. What’s more, its generous size makes it a great option for anyone hosting an upcoming summer gathering, whether it’s a pool party, outdoor barbecue, or last-minute trip to the beach.

Shoppers are already calling the new cake “dangerous”

The debut of Costco’s latest dessert has already generated plenty of buzz online. The Costco-focused food blogger costcoguide, for example, gave it a largely positive review on Instagram.

“It is so pretty! It has two different kinds of cake in here. The bottom chocolate layer kind of seems like a brownie,” the blogger shared. “It was pretty crumbly and hard to eat, but some of our guests really loved it. It would probably be good heated up over some vanilla ice cream.”

Gauging the reaction across social media, many customers similarly said they couldn’t wait to try the new item. “Oh my gawd!” one user commented on Instagram. “Wow, this looks incredible,” added another. “This is dangerous,” joked a third.

Many were also quick to point out that the dessert would be perfect for celebrations and casual get-togethers alike. “I would need help eating it,” remarked one shopper. “Perfect for a birthday cake!” suggested another.

Bottom line

While we’ll never say no to a piping hot s’more straight from the campfire, Costco’s S’mores Bundt Cake delivers a fun mashup of two classic desserts that members already seem eager to try. It leans into everything people love about traditional s’mores while adding a rich vanilla-and-chocolate Bundt cake base loaded with over-the-top toppings.

As tempting as the new dessert sounds, it’s worth remembering that there’s no telling how long Costco will keep the S’mores Bundt Cake on shelves. If it’s on your must-try list this summer, you may want to pick one up sooner rather than later.
