Costco's Coffee Cake Muffin is a beloved bakery item featuring a cream cake base with a buttery cinnamon streusel topping. Each large muffin weighs approximately 6 ounces with a 4-inch diameter, making them substantially sized compared to typical store-bought muffins. The muffins are baked fresh daily in Costco's bakery section and can be purchased in an 8-count package.

These muffins offer a sweet, indulgent breakfast or dessert option with a moist interior and crunchy streusel top. The Coffee Cake variety has been a fan favorite over the years, though it's often available as a seasonal or limited-time offering at select warehouses rather than a permanent menu item like the blueberry, chocolate, and almond poppyseed varieties.
