They represent everything we love about the Costco bakery: quality ingredients, generous portions, and an unbeatable price.
What’s Included in the Costco Pumpkin Muffin 8-Pack?
When you pick up the Pumpkin Streusel Muffins, you’ll find them in the fresh bakery section of the warehouse.

How Do They Actually Taste? An Honest Review
Overall, the Costco Pumpkin Streusel Muffins have a delightful, authentic pumpkin spice flavor with a wonderfully soft and moist texture. The first thing you notice is the rich aroma of cinnamon, ginger, and cloves the moment you open the container.
The muffin itself is dense yet tender, with a rich, satisfying crumb that feels moist without being oily. It’s perfectly sweetened, allowing the warm spice flavors to shine through. The real star, however, is the streusel topping. It’s a generous layer of buttery, cinnamon-sugar crumble that stays crunchy, providing the perfect textural contrast to the soft muffin below. It’s a well-balanced and incredibly satisfying muffin that genuinely tastes homemade.
