Get the scoop on the new Costco muffins (AKA Kirkland Signature muffins) in this 2025 Costco muffin review! Learn which is the best of the Costco muffin flavors (IMO), get the Costco muffin price, nutrition information, and more. If you’ve ever wondered if Costco muffins freeze well, or how long they last, I’ve got the answers here. Kirkland muffins are always a crowd-pleaser for breakfast, brunch, or a snack.
Why are Costco muffins so good? Costco muffins are soft, super moist, and cake-like in sweetness and texture. This is because they’re packed with white flour, sugar, and oil, just like a cupcake or pastry.
I mean, you can essentially think of a Costco muffin as a piece of cake without frosting. Delicious, delicious cake.
If you have a Costco membership, the table of muffins in the Costco bakery is hard to miss. And if you want the muffins, you need to go to your local Costco, as they’re not sold on the Costco website.
(Well, the Costco Business site appears to sell them, but not their regular site. Alternatively, you may be able to get them delivered with Instacart, if you don’t mind paying an extra fee.)
Costco muffins used to be huge and came in packs of six, with a minimum purchase of two packs. Now they’re smaller, sold in packs of eight, and you can buy just one package at a time.
Each pack comes with only one flavor. It would be great if Costco offered mixed variety packs, since I always want to try them all!
Costco Muffin 8-Packs
Starting in 2025, Costco locations have replaced their 6-packs of muffins with 8-packs of smaller-sized muffins. Readers report these muffins taste different, as they’ve changed the recipe as well.
➕ Costco Muffin Flavors
What flavor muffins does Costco make? Costco muffin flavors may vary by season and store location. Here are some muffin flavors Costco may have:

*These are the muffins Costco has now, at my local store. You may find other Costco muffin flavors depending on when and where you visit.
Costco pumpkin muffins are the best Costco muffins, IMHO. Make sure to pick up a package if you’re at a Costco during pumpkin spice season.
The blueberry Costco muffins are usually available year-round. The Costco chocolate muffins are usually there as well. They are fan favorites!
You can also (typically) get veggie muffins at Costco, but they’re in the frozen section instead of the bakery. The Garden Lites Veggies Made Great muffins at Costco contain hidden veggies. They come in tasty flavors like blueberry oat muffins.
