• Costco's beloved key lime pie has returned to warehouse shelves nationwide for summer 2026.
  • The oversized key lime pie weighs about 4 pounds and sells for $17.99.
  • Like previous years, the seasonal bakery item is expected to remain available only through late summer before disappearing from Costco stores again.

It’s always an exciting day whenever a popular item returns to Costco’s shelves. Whether you’re in the mood for crisp Cotton Candy Grapes or a hearty raspberry-filled sugar cookie, there’s no end to the great items one can hope to find with Costco’s summertime offerings.

But even when compared to its fellow bakery staples, Costco’s oversized key lime pie remains one of the warehouse brand’s most standout treats. A rich, sweet, refreshingly creamy pie ideal for pool parties or outdoor barbecues, multiple shoppers have reported seeing the fan-favorite bakery item return to warehouse locations across the country. And if it’s anything like years past, shoppers certainly won’t want to miss this tart and tangy dessert while it’s still available at Costco.

A Southern summer staple makes it way back to Costco

Like the iconic Southern specialty it’s based upon, Costco’s key lime pie features a base of lime-flavored cream filling piled into a crunchy graham cracker crust and topped off with a generous layer of whipped topping. The dessert effortlessly blends sweet and slightly sour together into an unforgettably tasty treat, especially when served chilled on a summer afternoon.

As great as the treat is on its own, perhaps the best thing about Costco’s key lime pie is its massive size and agreeable price tag. For just $17.99, shoppers can get their hands on a 4-Ib pie that’s big enough to feed an entire backyard barbecue, making it the perfect hassle-free dessert to serve for your next summer get-together.

A glowing stamp of approval from online shoppers

Given its generous size, budget-friendly cost, and deliciously creamy and tangy flavor profile, it’s hardly a surprise that most Costco members have been jumping for joy at the news of the key lime pie’s return to Costco.

Reflecting the whopping size of the pie, one Costco content creator humorously observed, “I’ve held newborn babies that weigh the same as this key lime pie. The @costco bakery continues to deliver us gold.”

Another Costco fan on Instagram went so far as to describe the summery dessert as “the creamiest key lime pie!” Other commenters shared similarly positive responses to the bakery item’s return, with one saying, “This is by far the sweetest pie I've ever had to date.”

A refreshing dessert that’s only available for a limited time

Sadly, as with most of Costco’s seasonal items, the key lime pie will likely only remain on shelves for a limited time this summer. In the past, Costco has kept the dessert in stock until the final days of August or early September, giving shoppers plenty of time to enjoy this memorable bakery dish before it once again disappears for the season.
