Kirkland Signature Lemon Raspberry Muffins from Costco's Bakery come in a package of 8 individually wrapped muffins, each weighing 110 grams (approximately 4 ounces), for a total net weight of 31 oz. Made with real butter as the second ingredient and whole raspberries as the third, these muffins have a hearty, homemade character with an open crumb structure and genuine muffin texture — a notable departure from typical commercial muffins.

Each muffin features a soft lemon-flavored streusel topping and is individually wrapped in artisanal brown parchment paper that folds into a flower-like shape around the base. The batter combines brown sugar, sour cream, and whole milk for depth of flavor and a moist, tender crumb. The sweetness is restrained compared to most commercial bakery products, making them well suited for breakfast. They are best enjoyed warmed — microwave for 20 seconds or bake at 350°F for 4–5 minutes to refresh the streusel texture.
