Kirkland Signature Mantecada Muffins are a fresh-baked interpretation of the classic Mexican butter muffin, sold in a convenient 8-count clear tray. Each muffin features a light, spongy crumb and mild buttery sweetness reminiscent of pound cake, inspired by the mantecada pastries found in traditional Mexican panaderías. The 23-ounce package retails for $6.99, making it an exceptional value for a bakery-quality treat.

These muffins are available at select Costco warehouse locations and are baked fresh in-store. Reviewers describe the flavor as similar to Angel Food Cake in sweetness but with the tender, dense texture of a muffin. They can be enjoyed plain straight from the package, sliced and served with warm butter and jam, or even broken into a bowl with milk for a childhood-inspired treat.

Mantecada Muffins store well at room temperature in an airtight container for 3-4 days, in the refrigerator for up to 7-10 days, or can be frozen in a zip-lock bag for longer storage. To defrost, transfer to the refrigerator overnight or microwave in short intervals until warmed through.
