Traditional Mexican-style mantecada muffins from Costco's bakery, featuring a sweet, spongy texture similar to pound cake. These fresh-baked muffins have a distinctive red muffin liner and offer a mild sweetness compared to other Costco muffin varieties. Each muffin weighs approximately 6 ounces with a moist, dense crumb that resembles angel food cake in flavor but with muffin texture and density.

The mantecadas can be enjoyed on their own, sliced in half and served with warm butter and jam, or placed in a bowl with milk poured over for a traditional preparation. They store well in an airtight container to preserve freshness and can be frozen for extended shelf life. These muffins are a less sweet alternative to Costco's chocolate chip and blueberry muffin offerings while maintaining the generous portion sizes Costco is known for.
