Every few months, a new Costco treat starts showing up in the pictures shoppers post online. The latest is a box of shortbread covered in Belgian chocolate, and fans are already hunting for it.

The Kirkland Signature Shortbread with Belgian Milk Chocolate costs $13.99 per box. A box holds 15 sizable cookies.
The details come from a Tasting Table report published October 29.
Spotted In Stores Before It Hits The Website
The cookies are not yet listed on Costco’s website. Shoppers reported seeing them in stores on social media.
That leaves many members waiting for the item to land at their local warehouse. The article notes that new Costco items often take a long time to roll out fully.
An Instagram account called @costcofam4u described the cookies as buttery shortbread cookies covered in Belgian milk chocolate.
The Taste Of A Chocolate Chip Cookie With A Shortbread Snap
The writer found that the cookies combine chocolate chip cookie flavor with the crumbly, buttery texture of shortbread.
Chunks of chocolate are generously dotted across the cookies, more than an Instagram video suggested.
The verdict: a valuable find that could pass for homemade if served among seasonal sweets. The writer says it is poised to join Costco’s best new bakery items of 2026.
What Reddit And Instagram Are Saying
Reddit reviewers were enthusiastic. One called the cookies fantastic, giant shortbread cookies with chocolate chips and said they are soft and dense. Another said it is hard to imagine them being bad.
An Instagram commenter wrote that a 15-pack of shortbread is a very convincing reason to take the long way through Costco.
Skeptics pushed back. One Redditor said nothing beats the massive box of Walkers but he is willing to test that theory.
The Criticisms
Not everyone is convinced. Some say dark chocolate chips would be better than milk chocolate.
Others say the ingredient list is overly complex. Traditional Scottish shortbread needs only three ingredients, which is the standard purists hold up.
Those are fair points. A simple recipe is hard to beat, but a chocolate-covered version appeals to a different craving.
How To Serve Them
The writer suggests warming the cookies briefly and serving them with vanilla ice cream. Another option is to dip them in coffee, tea or a seasonal latte.
They also make a great addition to a holiday cookie tray. Arrange them with fruit and nuts, and they look elegant with almost no work.
Tips For Shopping A New Costco Item
If you want to try them, call your warehouse or check the store’s bakery section during your next visit. New items can appear in some stores before others.
- Check the bakery aisle and the seasonal tables near the front of the store.
- Ask an employee if the item has arrived or is expected soon.
- Take a photo of the price tag so you can compare it next time.
- Look at the sell-by date, since baked goods are best fresh.
Make Your Own Shortbread At Home
True shortbread is a simple recipe with three ingredients: butter, sugar and flour. Cream softened butter with sugar, work in the flour, press the dough into a pan and bake at a low temperature until pale gold.
You can melt chocolate and dip the cooled cookies for a homemade version. A sprinkle of sea salt on top adds a nice contrast.
Wrap a few in a pretty tin, and you have a gift that costs far less than a store-bought box.
A Short Guide To Costco’s Bakery Treats
Costco’s bakery section is a favorite stop for many members. Seasonal items appear and disappear, and buzz online often drives people to hunt for the latest treat.
When a new item arrives, it helps to try it soon. Popular products can sell out quickly, and rollouts vary by store.
Compare the price per cookie as well. At $13.99 for 15 sizable cookies, this box works out to under a dollar each, which is a decent price for a chocolate-covered shortbread.
Storing Cookies So They Stay Fresh
Once you open a box, keep the cookies in an airtight container at room temperature. That preserves the buttery snap and keeps the chocolate from absorbing odors.
Avoid leaving them near a warm stove or in direct sunlight, since the chocolate can melt and the cookies can soften.
If you buy more than you can eat, share a few with a neighbor. A plate of shortbread is a nice way to say thank you for a favor.
Holiday Entertaining Made Simple
A box of 15 cookies is a handy thing to have when company stops by. Set them on a pretty plate, pour coffee and you have a visit that feels special in about five minutes.
They also pair well with fruit. Slices of pear or a handful of fresh berries balance the buttery sweetness, and the plate looks more generous.
If you are bringing a dessert to a party and have no time to bake, a box like this saves the day. Move the cookies to your own platter, and nobody will mind.
