6 Brand-New Costco Treats To Beat The Heat This May

The Best Costco New Items For May 2026 Include Tons Of Sweet Treats
Costco

My May grocery budget is absolutely quaking, all thanks to Costco. The warehouse has launched so many delicious treats that are downright perfect for summertime.

Leaning hard into viral food trends, this month’s lineup of new Costco arrivals channels the energies of high-end ice cream shops and patisseries. My most-anticipated item? The $9.99 pack of pistachio croissants that are loaded to the brim with pistachio cream, powdered sugar, and chopped nuts. I’m drooling just thinking about them.

Alongside this new bakery find, you’ll be able to track down sweet strawberry shortcake bites, viral candies, and even a new flavor of sourdough bread for all your breakfast needs.


These are all the seasonal sweets you’ll want to stock up on at Costco before they disappear this May.
