Everyone loves those jumbo Costco Pumpkin Muffins and now you can make them at home with this easy copycat recipe.

Super moist pumpkin muffins with spice and delicious streusel crumb topping, just like Costco makes them, and even better – homemade dessert muffins to bake this fall and winter when those cooler temps set in.

Costco is known for its delicious jumbo pumpkin muffins that everyone waits all year long for. I know that when it gets to the end of summer, I’m looking for these. What better time to make your own this fall season. When I got into fall mode last year I made these muffins, with their generous size so many times. 

These pumpkin muffins are sweet dessert bombs, tender, flavorful, and topped with a crumb Streusel topping and plenty of powdered sugar. I guess that’s why they are just one of the many awesome Costco bakery items you find well before the end of September.

But the truth is…you don’t need to wait until Costco puts them on the shelves this fall. While you might be tempted to wait for your next Costco run, you can have a bite of a Costco pumpkin streusel muffin by making these today.

They are so easy to make at home and are the best Fall sweet treat! So nothing can stop me from baking a batch and sharing my success recipe with you. With a little crisp air and some fall leaves, it makes you want to pack up some throw blankets for a fun day out to enjoy the colors and satisfy that sweet tooth.

Costco Pumpkin Muffins Ingredients

Sweetly soft pumpkin muffin:

• All the simplest ingredients to make the muffin batter plus pumpkin pie spice mix, and canned pumpkin puree (Libby Pure Pumpkin).
• Sour cream keeps the muffins creamy and helps them hold shape better.
• Vegetable oil – to trap all the good moisture inside and make the best, most tender muffins. Canola or coconut oil work great.

For Cinnamon Streusel Topping:

• Confectioner’s sugar for dusting.

What Makes Costco Muffins So Moist?

My copycat Costco crumb pumpkin muffins turn out moist because I add sour cream and vegetable oil.

Greek or vegan yogurt will work as well.

Kitchen Equipment

• 6-count Jumbo muffin tin and liners
• Mixing bowls

How to Make Costco Crumb Pumpkin Muffins 

Prepare The Spiced Pumpkin Batter

1. Preheat the oven to 350 degrees.
2. Line the muffin tin with muffin liners. Set aside. I use 6-count jumbo muffin tin and it needs jumbo liners!
3. In a large bowl, add flour, salt, baking soda, pumpkin spice, and cinnamon. Whisk until combined.
4. In a separate bowl, add the pumpkin, eggs, granulated sugar, sour cream, oil, and brown sugar to the flour mixture.  Mix together until just combined. 
5. Divide the batter among the 6 muffin cups filling 2/3 of each cup with batter.

Make The Topping

1. Combine the flour, butter, both types of sugar, and cinnamon in a small bow. Work the ingredients together with your fingers until it forms coarse crumbs.
2. Break up the crumbs and sprinkle all over each muffin.

Bake And Serve

1. Bake for 25-30 minutes or until the toothpick test comes out clean. 
2. Remove and cool to room temperature.
3. Before serving dust the tops with confectioner’s sugar or cinnamon.
4. Serve with whipped cream, vanilla ice cream, or maple icing.

How To Tell If The Pumpkin Muffins Are Done?

Pumpkin streusel muffins are done when they turn golden brown and are baked all the way through.

Check if the toothpick inserted in the center comes out clean and the top of the muffin bounces back if you lightly tap it. If yes – the muffins are done.

Jumbo pumpkin muffins take up to 30 minutes to bake through while mini muffins don’t need longer than 20 minutes at 350F.

Storage

Store leftovers of the pumpkin Streusel muffins in an airtight container in the refrigerator for up to 3 days.

If you don’t have a container, use plastic wrap to keep the moisture in the muffins and any other fridge smells out.

The next day these muffins seem even more moist!

Can You Freeze Pumpkin Muffins?

You can freeze pumpkin muffins in an airtight freezer bag for up to 3 months. That makes them worth stocking.

Before serving, warm the frozen muffins in the microwave, checking after each 15 seconds.

Variations Of The Costco Copycat Crumb Pumpkin Muffins

• Add chopped nuts for a nice crunchy texture. Walnuts and hazelnuts will work amazingly. Chocolate chips and dried fruit can be added too.
• Make homemade pumpkin spices mix – with cinnamon, allspice, nutmeg, ground ginger, and clover. Whisk it well in a small bowl and then add to the mixture. Even if you don’t mix your own spices, the recipe I use has just enough spice to enjoy the fall flavors.
• Add vanilla for aroma, it won’t really affect the flavor.
• These sweet and soft pumpkin muffins can become vegan: use almond or another alternative milk and plant-based butter for streusel. Eggs can be substituted by a store-bought egg replacement.
• You can also add buttermilk to the wet ingredients while making muffin batter. Store-bought buttermilk or homemade version made of milk and lemon juice will work.
• You can swap confectioner’s sugar, which is sugar + cornstarch, with powdered sugar (just granulated sugar) for dusting. They are not the same, but both work for the muffin recipes.
• Maple icing is just a cherry on top of these muffins. And it only needs 3 ingredients: milk, maple syrup, and confectioners’ sugar.
• You can always skip the crumb topping altogether and replace it with a topping you like. For me, these two are inseparable though!

Tips and Tricks To Bake The Best Pumpkin Muffins

• Pumpkin pie filling does not work in this recipe.
• You can make these using a standard 12-count muffin tin. Just start checking the muffins for doneness after baking for 15 minutes.
• You can turn this recipe into a pumpkin streusel bread recipe by baking it in a loaf pan. At 350F it will take around 60-75 minutes.
• A large cookie scoop helps to portion the batter between the cups in the tin. This spiced pumpkin muffin weighs in at a third of a pound.
• Always add dry ingredients to the wet ingredients. Rubber spatulas and wooden spoons work best for mixing the too and folding ingredients in.
• To make the best Streusel topping use only soft or melted butter and your hands. Don’t try to make crumbs with a fork, use your whole hands to squeeze the mixture.
• Add the crumbly topping right before baking the muffins. Otherwise, the crumbs will sink into the batter.
• I use all-purpose flour and add baking soda to make fluffy muffins. But you can use self-raising flour instead.
