A labeling error at Costco’s bakery has triggered a recall affecting customers at 11 warehouse locations across nine states and Puerto Rico.
On April 7, 2026, Costco issued a recall for its Traditional Madeleines after discovering that containers labeled as the traditional plain variety were mistakenly packed with a different product entirely: Madeleines filled with Chocolate Hazelnut spread. Because the outer packaging identifies only Traditional Madeleines, there is no allergen warning indicating the product contains hazelnuts — a tree nut that can cause severe and potentially fatal allergic reactions in those with tree nut allergies.
The recall is limited in scope but serious in risk. If you purchased Costco bakery madeleines between March 30 and April 6, 2026 at one of the affected locations, it’s worth checking what’s actually inside that container before anyone eats them.
What Happened
This is a packaging error, not a contamination issue. Costco’s Chocolate Hazelnut Madeleines (item number 2011285) were inadvertently placed in containers printed with the Traditional Madeleines label (item number 2000012). The two products look similar enough in their clamshell packaging that the mix-up may not be immediately obvious — but the contents are distinctly different, and for someone with a tree nut allergy, that difference matters enormously.
Under FDA requirements, any product containing a major allergen — including tree nuts — must carry proper allergen labeling. Because the Traditional Madeleines label contains no such warning, Costco recalled the product to protect customers who may be allergic to hazelnuts.
How to Tell If You Have the Recalled Product
The recalled containers are labeled as Traditional Madeleines and contain heart-shaped cookies. A closer look inside the packaging reveals the mix-up: some madeleines will have a pink raspberry filling, while others contain a darker chocolate hazelnut filling. The presence of those chocolate hazelnut-filled cookies is the giveaway that your container is part of the mislabeled batch.
Costco has posted a photo of the recalled product on its recall notice page to help customers identify the packaging.
Which Locations Are Affected
The recall covers purchases made between March 30 and April 6, 2026 at the following Costco warehouses:
- Missoula, MT
- Burlington, WA
- East Peoria, IL
- Bellevue, WI
- Pleasant Prairie, WI
- Chico, CA
- Thornton, CO
- Gilroy, CA
- Bayamon, PR
- Pembroke Pines, FL
- Fairfax, VA
If you didn’t purchase madeleines from one of these locations during that window, your product is not affected.
Who Needs to Act — and Who Doesn’t
This recall matters most to customers with tree nut allergies or sensitivities. Hazelnuts are classified as a tree nut and are one of the nine major food allergens recognized by the FDA. For people with tree nut allergies, exposure to hazelnuts can trigger reactions ranging from hives and vomiting to a severe drop in blood pressure or anaphylaxis — a life-threatening emergency that requires immediate medical attention.
For customers without tree nut allergies, Costco has confirmed that the mislabeled product is safe to consume — the issue is the labeling error, not the safety of the food itself. That said, returning the product for a refund is an option regardless of your allergy status.
Notably, This Isn’t the First Time
Worth noting: this is the second time in 2026 that Costco has recalled a bakery item due to a nearly identical packaging error. In late January, the chain recalled its Caramel-Filled Mini Beignets after those containers were also found to contain Chocolate Hazelnut-filled pastries — again with no allergen warning on the label. That recall spanned 22 states. The Madeleine recall is smaller in scope but raises similar questions about bakery packaging controls.
What to Do
If you have the recalled Traditional Madeleines and have a tree nut allergy — or live with someone who does — do not eat the cookies. Return the container to any Costco warehouse for a full refund. No receipt is required for recalled bakery items at Costco.

The Bottom Line
Costco recalled Traditional Madeleines sold at 11 warehouse locations between March 30 and April 6, 2026, after discovering the containers were mislabeled and actually contained Chocolate Hazelnut-filled madeleines. The undeclared hazelnut allergen poses a serious risk for customers with tree nut allergies. Return the product to Costco for a full refund if you purchased it at one of the affected locations.
