The Kirkland Signature Chocolate Banana Muffins are freshly baked jumbo muffins made exclusively in Costco warehouse bakeries. Each pack contains 12 oversized muffins totaling 70 ounces — approximately 5.8 ounces per muffin — making them significantly larger than standard store-bought muffins.

These muffins feature a pronounced, natural banana flavor using real bananas in the recipe, not artificial banana flavoring. Each muffin is generously studded with chocolate chips throughout, with a golden, slightly crisp exterior and a soft, moist interior. The banana flavor is prominent and noticeable from the first bite, balanced by rich chocolate chip pockets in every slice.

The muffins stay fresh at room temperature for 3–4 days and can be refrigerated for up to 7–10 days. For longer storage, wrap individually and freeze; defrost overnight in the refrigerator or warm in the microwave in 30-second intervals.
