Costco shoppers are heating up a popular bakery item in their air fryers, and the results have people talking.

What this means for you

The pastry causing all the buzz is the Blueberry Caramelized Cheesecake Croissant. This site exists to explain trends like this in plain words, because you should not need a dictionary to keep up with the news, even food news. Here is what you need to know if you want to try it yourself.

The croissant came back to Costco's Kirkland Signature bakery in mid-2026. It has a sweet sugar topping and a gooey blueberry filling inside. You can get six large pastries for $14.74 through Costco's Same-Day website.

The pastry has stayed popular partly because of a simple trick. Some shoppers online say the best way to enjoy it is to warm it in the air fryer.

1. Set your air fryer to 335 degrees Fahrenheit.
2. Leave the pastry inside its individual baking cup. This helps it keep its caramelized edges and bottom while it heats.
3. Air fry it for about three minutes, or adjust slightly based on how warm and soft you like it.

This croissant is not the only Costco bakery item people are air frying these days. Chocolate hazelnut mini beignets, which showed up at United States Costco stores in October 2025, are also getting the treatment. One Reddit user suggested air frying them and then rolling them in cinnamon sugar, calling it a "total game changer."

Costco's year-round Danish pastries are another favorite for this method. The bakery sells Cherry, Almond, and Cream Cheese Danishes all year, and both customers and workers say air frying them makes a real difference. Try five to eight minutes at 350 degrees Fahrenheit to get flakier bread and warmer, richer filling.

Seasonal options work too. The Strawberry Cheese Danish, for example, gets an even gooier filling when it goes through the air fryer, according to fans of the treat.

If you want to see what all the fuss is about, your next stop is simple. Pick up a box of the Blueberry Caramelized Cheesecake Croissants on your next Costco run, then set your air fryer for three minutes at 335 degrees and see if it lives up to the hype.
