Costco Pumpkin Muffin Recipe Ingredients

For the Muffins:

• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 ½ teaspoons cinnamon
• 1 ½ teaspoons pumpkin pie spice
• 15 ounces pumpkin puree (1 can – not pumpkin pie filling)
• 2 eggs
• ¾ cup granulated sugar
• ½ cup sour cream
• ⅓ cup vegetable oil
• ¼ cup brown sugar

For the Topping:

• ½ cup all-purpose flour
• 6 tablespoons butter, softened
• ¼ cup granulated sugar
• 3 tablespoons brown sugar
• 1 teaspoon cinnamon
• Confectioner’s sugar for dusting

How To Make Costco Pumpkin Muffins

1. Prepare Oven and Pan: Preheat the oven to 350°F. Line a 6-count jumbo muffin tin with jumbo paper liners and set it aside.
2. Combine Dry Ingredients: In a large bowl, whisk together the 2 cups of flour, baking soda, pumpkin pie spice, and 1 ½ teaspoons of cinnamon until well combined.
3. Mix Wet Ingredients: In a separate medium bowl, add the pumpkin puree, eggs, granulated sugar, sour cream, vegetable oil, and brown sugar. Mix together with a whisk or spatula until just combined.
4. Make the Batter: Pour the wet pumpkin mixture into the dry ingredients. Stir gently until just combined. Be careful not to overmix the batter.
5. Make the Crumb Topping: In a small bowl, combine the ½ cup of flour, softened butter, both types of sugar, and 1 teaspoon of cinnamon for the topping. Use your fingers or a fork to work the ingredients together until the mixture forms coarse crumbs.
6. Fill and Top the Muffins: Divide the muffin batter evenly among the 6 jumbo muffin cups. Sprinkle the crumb topping generously over each muffin.
7. Bake and Cool: Bake for 25 to 30 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Let the muffins cool to room temperature before dusting the tops with confectioner’s sugar.

Recipe Tips

• How do I get a moist muffin? The combination of pumpkin puree, sour cream, and oil makes these muffins incredibly moist. The key is not to overmix the batter once you combine the wet and dry ingredients, which can make them tough.
• How do I get a perfect crumb topping? Use butter that is softened, not melted. Work the ingredients together with your fingertips until it resembles coarse, sandy crumbs. This will ensure the topping bakes up crispy and crumbly, rather than melting into the muffin.
• Can I use pumpkin pie filling instead of pumpkin puree? No, you must use 100% pure pumpkin puree. Pumpkin pie filling is already sweetened and spiced, which will throw off the flavor and sweetness of this recipe.
• How do I know when the muffins are done? The toothpick test is the most reliable method. Insert a toothpick or a wooden skewer into the center of the largest muffin. If it comes out clean or with a few moist crumbs attached, they are ready.
