Costco has added a new sweet treat to its bakery lineup with the debut of its Peanut Butter Monster Cookies.
“Peanut butter lovers, this one’s for you,” Costco wrote in an Instagram post this week. “The new Peanut Butter Monster Cookies are at the Costco Bakery!”
The 24-count packages feature cookies made with brown butter–flavored dough and packed with peanut butter candies, peanut butter chips, oats and chocolate chunks, according to Delish.
Shoppers quickly took to Costco’s Instagram comments section to praise the new Peanut Butter Monster Cookies.
“These are the best!!!!” one user wrote.
“Can’t wait to try these!” another added.
“Yess,” a third user wrote, alongside a heart-eyes emoji. “Love peanut butter.”
The Peanut Butter Monster Cookies add to Costco Bakery’s current lineup, which includes its blueberry and cream muffins, butter croissants, chocolate chunk cookies, cheesecakes, danishes and more.
The new cookie launch comes as Costco Wholesale recently unveiled a string of record-breaking sales during the holiday season.
The retailer said it sold about 4.5 million pies in the three days leading up to Thanksgiving — roughly 7,000 pies per warehouse — during its Q1 2026 earnings call.
Costco did not immediately respond to FOX Business’ request for comment.
