As many worthwhile items as the warehouse chain has in supply year-round, Costco’s latest seasonal product might take the cake as the store’s most exciting treat of the summer. Providing a citrus-centric spin on an age-old dessert, Costco’s new Lemon Blondie Bars are already catching the attention of shoppers online, many of whom were quick to call the dessert “the perfect summer treat!”

A tangy twist on a classic dessert

As shoppers might readily gather from the name, Costco’s Lemon Blondie Bars are a refreshing take on the traditional blondie. Combining the signature vanilla-forward flavor profile of a blondie with a burst of lemon filling in every bite, the new treat offers the ideal balance between sweet and tart.

As if that weren’t exciting enough, each bar also features a generous drizzle of white chocolate, allowing for an even more satisfying dessert for your next pool party, camping trip, or Fourth of July celebration.

The new treat has online fans calling for an urgent ‘Costco run’

Like many of Costco’s seasonal desserts and other limited-edition bakery items, the brand’s Lemon Blondie Bars have gained significant traction among longtime shoppers. Many fans called the dessert a must-try for the summer season, complimenting its sweet-sour flavor combo and "irresistible" appearance.

“These would be perfect for summer BBQs, family gatherings, or just treating yourself after a Costco run,” shared one user on Instagram. Another post featured similarly positive comments from users, with one account writing, “Lemon filling + white chocolate drizzle?! That’s it, [time for a] Costco run!”

Before you head to Costco

Judging from reports across social media, Costco is currently stocking up on the Lemon Blondie Bars at nationwide warehouses. However, as with many of Costco’s items, availability depends significantly on location. To make sure your nearest store has the new desserts in inventory, you might want to check out Costco’s official website or app before heading out on your next grocery trip.

With its in-store price set at $8.99 per 16-bar package, the Lemon Blondie Bars are guaranteed to provide shoppers with a sweet, satisfying treat to enjoy at any point during the summer. Like many of the brand’s baked goods, though, there’s no telling how long they’ll remain on shelves—so you might want to toss a container or two in your shopping cart the next time you’re in Costco’s bakery section!
