These Are Costco's 9 Best Cakes Of 2026 — So Far

Out of all the tempting desserts sold at the chain, few are as exciting as Costco's popular cakes. Often sporting fun flavors, stunning visual appeal, and gigantic portion sizes, it's no wonder shoppers go wild when brand-new layer cakes, cheesecakes, and more join the bulk retailer's lineup. So far, 2026 has brought several never-before-seen cakes to warehouse shelves, and we've selected the best treats of the year that have already become fan favorites.

We looked at taste tests, reviews, and social media buzz from Costco shoppers to find out which new cakes earned the most raves, delivering uniqueness, great value, and a top-notch taste in every sweet bite. In 2026, eye-catching, social media-ready treats have dominated Costco shelves, along with trendy flavors like salted caramel and Dubai chocolate. The chain's popular Kirkland Signature bar cakes also keep generating hype, with two new varieties debuting over the summer to much praise.

Costco's newest ice cream-inspired bar cake made a splash when it hit U.S. stores in June. The Kirkland Signature Waffle Cone Bar Cake pairs waffle cone-flavored cake with waffle cone pieces, marbled icing, and adorable mini waffle cones. Customers say the mix of creamy and crunchy textures is irresistible, while the flavor is akin to tiramisu and tres leches cake. "It may genuinely be [in the] top three cakes of all time for me," one Redditor wrote.

The 2.8-pound Kirkland Signature Waffle Cone Bar Cake is still available at Costco for $21.55.

This is another treat full of nostalgic summer flavors; Costco added Jean's Posh Pantry S'mores Bundt Cakes to U.S. shelves in late June, and it's still up for grabs in July. This 36-ounce cake features chocolate-and-vanilla marbled cake with oversized marshmallows, graham cracker crumbles, and chocolate generously piled on top. While tasty as-is, shoppers recommend heating up a slice for that melty s'mores effect and serving with milk or ice cream to cut the richness.

Another Canadian Costco dessert that you won't find in America, the seasonal, spring-friendly Limoncello Mascarpone Cake won raves for its wonderfully strong citrus flavor, created by layers of lemon cake and curd, balanced by a creamy mascarpone and white chocolate spread.
