Costco’s Kirkland Signature Butter Cinnamon Sugar Loaf has reappeared in warehouses and on Costco.com after years of on‑again, off‑again appearances. The seasonal loaf has been spotted in stores since June, with availability varying by location. A Costco employee told Fox News Digital that the treat is seasonal, and shoppers have been racing to grab it while it’s in stock. The loaf is priced at $9.99 for a 38-ounce loaf.
Described as an all‑butter pound cake with thick cinnamon swirls and a coating of cinnamon sugar, the loaf weighs about 38 ounces and is sold as a single loaf. Costco’s site lists about 410 calories and 33 grams of sugar per serving. Fans online have recounted that the loaf contains a substantial amount of butter and that the coating clings to the exterior through melted butter, contributing to its rich reputation. Availability tends to ebb and flow by store, reflecting its seasonal nature.
The Butter Cinnamon Sugar Loaf first appeared at Costco as early as 2017 and was last widely seen in 2023 before its latest June resurgence. The loaf has inspired passionate chatter on Reddit, Instagram, and TikTok, with fans calling it addictive, dangerous, and the best loaf cake they’ve tasted. Posts have drawn comparisons to a Sara Lee pound cake with churro dusting and have spurred conversations about how to savor or repurpose the treat.
Fans have shared a range of ways to enjoy the loaf, from freezing portions for later to turning slices into French toast or warming them briefly in an air fryer. Laura Lamb, creator of the Costco Hot Finds account, demonstrated French toast made with the loaf, calling it an exceptional option for a quick, indulgent breakfast. Other social-media contributors suggested simple hacks like toasting slices or pairing the loaf with coffee as a treat for mornings or afternoons.
Costco has kept the price near $9.99, roughly the same per‑weight rate as the three‑loaf packs that previously included the item. The resurgence places the Butter Cinnamon Sugar Loaf alongside other seasonal cult favorites at the chain, such as the nearly 4-pound pumpkin cheesecake and the peaches and cream bar cake, both of which have enjoyed their own short-lived returns in past years. As with prior runs, availability can be inconsistent, and shoppers are advised to check local warehouses or Costco.com for the latest stock.
Fox News Digital reached out to Costco for comment on the loaf’s latest release and seasonal status. The retailer has historically treated the item as a seasonal bakery offering, with distribution varying by market and occasional gaps during the year. Given the pattern of past appearances, fans anticipate the loaf may reappear again as supply and demand align, but no firm timetable is provided.
If you’re hoping to snag a Butter Cinnamon Sugar Loaf, the best strategy is to monitor Costco’s online storefront and your local warehouse, especially in months when seasonal items tend to circulate. For those who have already enjoyed it, the loaf’s distinctive butter-forward richness and cinnamon glaze have already left a lasting impression, contributing to its status as a cult favorite among Costco’s bakery lineup.
