For the Muffins:
- 1 1/2 Cups Sugar
- 1/2 Cup Vegetable Oil
- 3 Eggs
- 1 tbsp Vanilla Extract
- 1 (15 oz) Can Pumpkin Puree
- 2 Cups Flour
- 1/2 tbsp Baking Powder
- 1 tsp Baking Soda
- 1/4 tsp Salt
- 1 1/2 tsp Cinnamon
- 1/2 tsp Ginger
- 1/2 tsp Nutmeg
- 1/2 tsp Cloves
- 2 tbsp Milk
For the Streusel:
- 1/2 Cup Flour
- 1/4 Cup Sugar
- 5 tbsp Brown Sugar
- 1/2 tbsp Cinnamon
- 6 tbsp Softened Butter
How To Make Costco Pumpkin Streusel Muffins
- Prep the oven and mix wet ingredients: Preheat your oven to 325°F. Line two standard 12-cup muffin trays with paper liners. In a large bowl, whisk together the sugar and vegetable oil. Add the eggs and vanilla and whisk until well combined. Whisk in the pumpkin puree.
- Add the dry ingredients: In a separate bowl, sift or whisk together the flour, baking powder, baking soda, salt, and all the spices. Add the dry ingredients to the wet pumpkin mixture and mix until just combined. Gently fold in the milk.
- Make the streusel topping: In a small bowl, combine the flour, sugar, brown sugar, and cinnamon for the streusel. Add the softened butter and use your fingertips or a fork to mix until a crumbly, combined texture is formed.
- Assemble the muffins: Using a large cookie scoop, divide the batter evenly among the 24 prepared muffin cups. Sprinkle about 1 tablespoon of the streusel topping over each muffin.
- Bake and cool: Bake for 23-27 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Let the muffins cool in the pans for a few minutes before transferring them to a wire rack to cool completely.

Recipe Tips
- How to get fluffy, tender muffins: The most important rule is to not overmix the batter after adding the flour. Mix only until you no longer see streaks of dry flour. A few lumps in the batter are perfectly fine and are the secret to a tender crumb.
- How to get the perfect streusel: Using softened, room temperature butter is key. It allows you to easily work it into the dry ingredients with your fingers to create those perfect little crumbs that get crispy when baked.
- Can I use fresh pumpkin puree? Yes, but the consistency can vary. Canned pumpkin puree is typically very thick. If your homemade puree is watery, it can make the batter too thin. It’s best to drain it in a cheesecloth-lined sieve or cook it down slightly to thicken it first.
- How do I know when the muffins are done? The toothpick test is the most reliable method. The tops of the muffins should also spring back when lightly touched. Be careful not to over-bake, as that can lead to dry muffins.
What To Serve With Pumpkin Streusel Muffins
These muffins are a complete treat on their own, perfect for a grab-and-go breakfast or afternoon snack. They pair wonderfully with:
- A hot cup of coffee or a latte
- A cold glass of milk
- A simple smear of salted butter
How To Store Pumpkin Streusel Muffins
Room Temperature: Store the muffins in an airtight container at room temperature for up to 4 days. Placing a paper towel in the container can help absorb excess moisture and keep the streusel topping from getting soggy. Freeze: These muffins freeze beautifully. Let them cool completely, then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. Thaw at room temperature or gently reheat in the microwave.

FAQs
This is a popular “copycat” recipe that aims to replicate the flavor and texture of the famous seasonal pumpkin streusel muffins from the Costco bakery. While not the official recipe, it’s a beloved version that many enjoy making at home.
Yes. The recipe notes suggest you can bake the batter in two loaf pans. They will need a much longer baking time, around 60-75 minutes at 325°F. Use the toothpick test to check for doneness.
This can happen if the muffin batter is too thin or if the streusel is too heavy. Ensure your pumpkin puree isn’t overly watery. You can also try chilling the streusel topping for 10 minutes before sprinkling it on top to help it stay put.
