Costco's Lemon Blueberry Muffins are jumbo-sized bakery muffins featuring a moist, tender crumb infused with bright lemon flavor and sweet blueberries. Baked fresh in the Costco bakery, these oversized muffins have a golden, lightly crisp dome and a soft interior packed with blueberry pieces throughout.

The muffins offer a mildly sweet, citrus-forward flavor profile, with refreshing lemon zest complementing the juicy blueberries. They are ideal for breakfast, brunch, or as a snack. The generous size makes each muffin a satisfying treat on its own. Sold in multi-packs, these muffins are also freezer-friendly for extended freshness.
