Costco’s bakery case just pulled off a mash-up so good it shouldn’t even be legal. The Kirkland Signature Twice Baked Cinnamon Filled Croissants have been quietly selling out of warehouses since their late-July debut, and now that fall baking season is in full swing, they’re having an all-out viral moment — food blogs, TikTok reviewers, and the entire Costco fan internet are calling them the bakery’s best release of the year. If you haven’t spotted the six-pack clamshell near the muffins yet, consider this your sign to go look.
What Even Is a “Twice Baked” Cinnamon Croissant?
Here’s the concept: take a flaky, buttery croissant, stuff it with a cinnamon-sugar cream filling, then bake it a second time so the outside crisps up instead of staying soft. After that second bake, each one gets brushed with simple syrup, rolled in a crunchy cinnamon-sugar streusel, and finished with a dusting of powdered sugar. The result tastes like a cinnamon roll, a croissant, a churro, and a coffee cake all had one very delicious baby. You get six of them for $9.99, which works out to under $1.70 apiece — cheaper than a single pastry at most coffee shops, and this one comes with three times the layers.
It’s the latest in a long line of Costco bakery items that have gone properly viral this year, joining the ranks of the Kirkland Marshmallow Crispy Cookies that broke TikTok earlier this year. Costco’s bakery team has clearly figured out that “mash-up dessert” is the winning formula, and shoppers are here for it.
“The outside is dipped in a sugar cinnamon streusel which is incredible! It’s basically a churro croissant,” one shopper raved online — and honestly, that description alone should be enough to send you to the bakery aisle.
The Reviews Are (Almost) Unanimously Obsessed
Food reviewers who’ve actually taste-tested the croissants are backing up the hype. One outlet gave them a perfect 10/10, praising how “the extra crispiness of the twice baked element pairs perfectly with the gooey cinnamon center” while noting the pastry is “not egregiously sweet” — a rare compliment in the world of Costco bakery treats, which can sometimes lean cloying. Another shopper compared it directly to a fan-favorite discontinued item, writing, “If you loved that cinnamon butter cake from a while ago, you will love these even more.” That’s a big claim in Costco bakery circles, where nostalgia runs deep — just ask anyone still mourning items from the list of discontinued Kirkland favorites that occasionally make a comeback.
Should You Rush the Bakery Aisle This Week?
Short answer: yes, and don’t dawdle. Like nearly every other viral Costco bakery item this year — including this year’s buttermilk biscuits — these croissants seem to be selling in waves, popping back up and disappearing again as warehouses restock. They’re best eaten the same day or gently reheated in the oven (not the microwave, unless you want a soggy pastry) to bring back that crisp streusel shell. Pro tip from shoppers: they pair perfectly with a cup of coffee for a five-minute breakfast that tastes like way more effort than it actually was.
At under $2 a croissant, this is one of those rare viral finds that actually lives up to the algorithm’s promises. Grab a pack next time you’re doing a warehouse run — just don’t be surprised if it doesn’t make it home in one piece.
