Get the scoop on the new Costco muffins (Kirkland Signature) in this 2025 Costco muffin review. Find my top pick among the Costco muffin flavors, current Costco muffin price, nutrition details, storage tips, and whether Costco muffins freeze well. Kirkland muffins are a popular choice for breakfast, brunch, or a snack.
Why are Costco muffins so good? The muffins are soft, moist, and cake-like because they are made with white flour, sugar, and fat, giving them a rich, dessert-like texture. Think of a Costco muffin as an unfrosted cupcake—sweet and very satisfying.
These bakery items are made in-store at Costco warehouses and are typically only available for purchase at the warehouse (some locations or delivery services may carry them, but availability varies).
Costco shifted from selling large 6-packs to smaller muffins sold in 8-packs. Each package contains a single flavor rather than a mixed assortment.
Costco Muffin 8-Packs
Starting in 2025, Costco replaced six-packs with eight-packs of smaller muffins. Some shoppers note the recipe changed slightly, which may affect taste and texture.
➕ Costco Muffin Flavors
What flavor muffins does Costco make? Flavors vary by season and location. Common flavors you may see include:
- Lemon Raspberry
- Blueberry & Cream
- Triple Chocolate
- Butter Pecan
- Cinnamon Chip
- Guava Cream Cheese

- Corn
- Almond Poppy Seed
- Pumpkin Streusel
Seasonal favorites like pumpkin often sell out fast—pick up a package during pumpkin-spice season if you want to try it.
