In mid‑June 2026, Costco rolled out a broad frozen‑treat range including mango‑only pops, Häagen‑Dazs Mini Dubai‑style chocolate bars, and Nightingale Brookie Dough Ice Cream Sandwiches. Simultaneously, Albertsons highlighted top‑selling frozen items such as Kinder Bueno Frozen Dairy Dessert and Dole Whip Tropical Guava Passion. By early July, Costco expanded its assortment to include home goods, fashion, and beauty items like Ninja blenders and Puma sneakers. The retailer also revived the limited‑time Kirkland Signature Marshmallow Crispy Cookies at $9.99 for a 24‑pack, which sparked online discussion regarding freezing tips. A July 27 update noted the Marshmallow Crispy Cookie reappeared in a 36‑oz clamshell, alongside the debut of a $2.99 Vanilla Cookie Crunch Sundae in the food court. The sundae, featuring vanilla soft‑serve with chocolate syrup and Oreo‑style crumbles, prompted both praise and concerns that it might replace the Strawberry Shortcake Sundae. Throughout late July and August, Costco continued rotating exclusive, affordable items to drive foot traffic. This included an August lineup featuring Burberry perfume, Hunter boots, and electrolyte drinks. New August additions also included a seasonal Cherry Almond Coffee Cake, FØRTE protein bars, and VAHDAM turmeric tea. Influencer engagement and comparisons to similar treats at Sam’s Club highlighted Costco’s ongoing strategy of using rotating, value-focused indulgences to reinforce its brand image. ## Timeline ### 2026-08-17: Costco introduces new seasonal bakery items and protein snacks Costco has launched several new seasonal and protein-focused food items this August, including a Cherry Almond Coffee Cake and various protein-rich snacks and beverages. 3 sources. https://clstr.news/cluster/costco-introduces-new-seasonal-bakery-items-and-protein-snacks ### 2026-07-31: Costco launches new August product lineup and limited‑edition Vanilla Cookie Crunch Sundae Costco adds dozens of new August items and rolls out a $2.99 Vanilla Cookie Crunch Sundae, sparking social‑media buzz and competition with Sam’s Club. 8 sources. https://clstr.news/cluster/costco-launches-new-august-product-lineup-and-limitededition-vanilla-cookie-crunch-sundae ### 2026-07-27: Costco launches Marshmallow Crispy Cookies and Vanilla Cookie Crunch Sundae Costco added a Kirkland Marshmallow Crispy Cookie and a $2.99 Vanilla Cookie Crunch Sundae to its offerings, sparking shopper enthusiasm and concerns about the Strawberry Shortcake sundae’s future. 2 sources. https://clstr.news/cluster/costco-launches-marshmallow-crispy-cookies-and-vanilla-cookie-crunch-sundae ### 2026-07-02: Costco launches July product lineup and revives Marshmallow Crispy Cookies Costco's July rollout adds 12 new items—from kitchen appliances to fashion—and brings back Kirkland Marshmallow Crispy Cookies for $9.99, hailed as “dangerously delicious” online. 5 sources. https://clstr.news/cluster/costco-launches-july-product-lineup-and-revives-marshmallow-crispy-cookies ### 2026-06-18: Albertsons Highlights Top Frozen Food Picks for 2026 Albertsons shoppers favor four frozen foods in 2026: Kinder Bueno dessert, Boston Market pork mac & cheese, Dole Whip guava, and Stouffer’s Chicken, all priced under $6 and stocked online through June 23. 2 sources. https://clstr.news/cluster/albertsons-highlights-top-frozen-food-picks-for-2026 ### 2026-06-12: Costco expands 2026 product line with new frozen treats and seasonal grocery items Costco's 2026 lineup adds numerous frozen treats—mango pops, fruit‑shaped ice creams, mini Dubai bars—and new grocery items such as smoked pork ribs, probiotic yoggies, protein lattes and seasonal seasonings. 3 sources. https://clstr.news/cluster/costco-expands-2026-product-line-with-new-frozen-treats-and-seasonal-grocery-items --- Cite as: US grocery and Costco product launch trends 2026.
